10 Worst Computer Viruses in history

Computers viruses, worms, ransomware, etc. are kinds of malicious software that no user should take lightly. On several occasions, we have touched upon security steps that each user should take in order to protect its identity and data. Sadly sometimes even when all precautions are taken some malware can still slip through and wreak havoc. Today we are looking at some of the worst or the best, depending on your view that has indeed wreaked plenty of havoc.

10 worst computer viruses in history

In the list of the 10 most famous computer viruses below, we show the costs, dates, reach, and other key facts. First a note about terms: we use the words “virus” and “worm” interchangeably because most readers search for them that way. But there’s a subtle difference that we explain after the list.

1. Mydoom – $38 billion

The worst computer virus outbreak in history, Mydoom caused estimated damage of $38 billion in 2004, but its inflation-adjusted cost is actually $52.2 billion. Also known as Novarg, this malware is technically a “worm,” spread by mass emailing. At one point, the Mydoom virus was responsible for 25% of all emails sent.
Mydoom scraped addresses from infected machines, then sent copies of itself to those addresses. It also roped those infected machines into a web of computers called a botnet that performed distributed denial of service (DDoS) attacks. These attacks were intended to shut down a target website or server.

Mydoom is still around today, generating 1% of all phishing emails. That’s no small feat considering the 3.4 billion phishing emails sent each day. By that figure, Mydoom has taken on a life of its own, infecting enough poorly-protected machines to send 1.2 billion copies of itself per year, 16 years after its creation.
Though a $250,000 reward was offered, the developer of this dangerous computer worm was never caught.

2. Sobig – $30 billion

The 2003 Sobig computer virus is actually another worm. It is second only to the Mydoom virus in its scope. The $30 billion figure is a worldwide total, including Canada, the U.K., the U.S., mainland Europe, and Asia. Several versions of the worm were released in quick succession, named Sobig.A through Sobig.F, with Sobig.F being the most damaging.
This cybercriminal program masqueraded as legitimate computer software attached to emails. It disrupted ticketing at Air Canada and interfered with countless other businesses. Despite its widespread damage, the creator of the successful bug was never caught.

3. Klez – $19.8 billion

Klez is a close third on the list of the worst computer viruses ever created. With nearly $20 billion in estimated damages, it infected about 7.2% of all computers in 2001, or 7 million PCs. The Klez worm sent fake emails, spoofed recognized senders and, among other things, attempted to deactivate other viruses.
As with other viruses and worms, Klez was released in several variants. It infected files, copied itself, and spread throughout each victim’s network. It hung around for years, with each version more destructive than the last.
Windows has come a long way since most of the computer viruses on this list hit the web. Thankfully, built-in protection with Microsoft Defender is always on the watch.

4. ILOVEYOU – $15 billion

The year 2000’s ILOVEYOU virus worked by sending a bogus “love letter” that looked like a harmless text file. Like Mydoom, this attacker sent copies of itself to every email address in the infected machine’s contact list. Shortly after its May 4 release, it had spread to more than 10 million PCs.
The virus was created by a college student in the Philippines named Onel de Guzman. Lacking funds, he wrote the virus to steal passwords so he could log into online services he wanted to use for free. He reportedly had no idea how far his creation would spread. This virus is also known as Loveletter.

5. WannaCry – $4 billion

The 2017 WannaCry computer virus is ransomware, a virus that takes over your computer (or cloud files) and holds them hostage. The WannaCry ransomware ripped through computers in 150 countries, causing massive productivity losses as businesses, hospitals, and government organizations that didn’t pay were forced to rebuild systems from scratch.
The malware raged like wildfire through 200,000 computers worldwide. It stopped when a 22-year-old security researcher in the U.K. found a way to turn it off. Computers with out-of-date operating systems were hit especially hard. That’s why security experts always recommend updating your systems frequently.

Ransomware strikes again

In September 2020, one of the potentially largest computer virus attacks in medical history hit Universal Health Services. The U.S. hospital chain, which has more than 400 locations, was reportedly struck by damaging ransomware. The attack forced the cancellation of surgeries and made healthcare workers switch to paper records.

6. Zeus – $3 billion

The Zeus computer virus is an online theft tool that hit the web in 2007. A whitepaper by Unisys three years later estimated that it was behind 44% of all banking malware attacks. By then, it had breached 88% of all Fortune 500 companies, 2,500 organizations total, and 76,000 computers in 196 countries.
The Zeus botnet was a group of programs that worked together to take over machines for a remote “bot master.” It originated in Eastern Europe and was used to transfer money to secret bank accounts. More than 100 members of the crime ring behind the virus, mostly in the U.S., were arrested in 2010. It’s not as prominent today, but some of the virus’ source code lives on in newer botnet viruses and worms.

Zeus caused documented damage of $100 million. But the real cost in terms of lost productivity, removal, and undocumented theft is undoubtedly much higher. A $3 billion estimate, adjusted for inflation, puts this virus at a cost of $3.7 billion in today’s dollars.

7. Code Red – $2.4 billion

First observed in 2001, the Code Red computer virus was yet another worm that penetrated 975,000 hosts. It displayed the words “Hacked by Chinese!” across infected web pages, and it ran entirely in each machine’s memory. In most cases it left no trace in hard drives or other storage.
Financial costs are pegged at $2.4 billion. The virus attacked websites of infected computers and delivered a distributed denial of service (DDoS) attack on the U.S. White House’s website, www.whitehouse.gov. In fact, the White House had to change its IP address to defend against Cod Red.

8. Slammer – $1.2 billion

The SQL Slammer worm cost an estimated $750 million across 200,000 computer users in 2003. This computer virus randomly selected IP addresses, exploiting vulnerabilities and sending itself on to other machines. It used these victim machines to launch a DDoS attack on several internet hosts, significantly slowing internet traffic.
The Slammer worm hit banks in the U.S. and Canada especially hard, taking ATMs offline in many locations. Customers of Toronto’s Imperial Bank of Commerce found themselves unable to access funds. The attack reared its ugly head again in 2016, launching from IP addresses in Ukraine, China, and Mexico.

9. CryptoLocker – $665 million

Thankfully, ransomware attacks like the 2013 CryptoLocker virus have dipped since their 2017 peak. This malware attacked upwards of 250,000 machines by encrypting their files. It displayed a red ransom note informing users that “your important files encryption produced on this computer.” A payment window accompanied the note.
The virus’ creators used a worm called the Gameover Zeus botnet to make and send copies of the CryptoLocker virus. According to a report by security firm Sophos, the average ransomware attack costs a business $133,000. If we estimate that CryptoLocker hit 5,000 companies, that would put its total cost at $665 million.

10. Sasser – $500 million

The Sasser worm was written by a 17-year-old German computer science student named Sven Jaschan. He was arrested at the age of 18 in 2004 after a $250,000 bounty was posted for the computer virus’ creator. A friend of Jaschan’s tipped authorities that the youth had penned not only the Sasser worm but also the damaging Netsky.AC attack.
Jaschan was given a suspended sentence after it was found he was a minor when he wrote the malware. The Sasser worm crashed millions of PCs, and though some reports put damages at $18 billion, the relatively low infection rate suggests a more likely cost of $500 million.
Other notable viruses

The top 10 worst computer viruses above are just the ugly tip of a gargantuan digital iceberg. With a million new malware programs popping up every 3 years, we may miss the forest for a few outstanding trees. Here are just a few more viruses that have wreaked havoc over the years:

Mimail: This worm tried to harvest data from infected machines to launch a string of DDoS attacks, but was relatively easy to remove.

Yaha: Yet another worm with several variants, thought to be the result of a cyber-war between Pakistan and India.

Swen: Written in C++, the Swen computer worm disguised itself to look like a 2003 OS update. Its financial cost has been pegged at $10.4 billion, but not reliably.

Storm Worm: This worm showed up in 2007 and attacked millions of computers with an email about approaching bad weather.

Tanatos/Bugbear: A 2002 keylogger virus that targeted financial institutions and spread to 150 countries.

Sircam: A computer worm from 2001 that used counterfeit emails with the subject line, “I send you this file in order to have your advice.”

Explorezip: This worm used fake emails to spread to every machine on thousands of local networks.

Melissa: The most dangerous computer virus in 1999, Melissa sent copies of itself that looked like NSFW pics. The U.S. FBI estimated cleanup and repair costs at $80 million.

Flashback: A Mac-only virus, Flashback infected over 600,000 Macs in 2012 and even infected Apple’s home base in Cupertino, Calif. In 2020, there’s now more malware on Macs than on PCs.

Conficker: This 2009 virus still infects many legacy systems and could do significant damage if it ever activates.

Stuxnet: This worm is reported to have destroyed Iranian nuclear centrifuges by sending damaging instructions.

Easy Remove FoxTab From Windows

FoxTab Toolbar is a browser hijacking toolbar add-on for IE, Firefox, Chrome, and Opera browsers that claims that it allows you to access your favorite sites faster, and improving your overall search and browsing experience. 1-click access to search results, most popular websites, and web services directly from our Foxtab browser toolbar.

Fox tab will integrate itself into your browser, modifying the search engine, welcome page, and new tab. This toolbar may change some browser settings, display unwanted ads, and sometimes displays additional ads from its ad sponsor. Some of the settings that this toolbar changes can lower the security of your browser.

Upon installation the toolbar ads scheduled tasks in Windows, allowing it to run with your browser every time, and to automatically update itself. Several anti-virus programs have flagged this software as Malware and therefore it is classified as a browser hijacker and recommended for optional removal.

About Browser Hijackers

Browser hijackers (sometimes called hijackware) are a type of malicious software that modifies internet browser settings without the user’s knowledge or approval. These types of hijacks are rising at an astonishing rate across the world, and they can be actually nefarious and sometimes dangerous too. They are created to interfere with web browser programs for many different reasons. Often, hijackers will force hits to internet sites of their choice either to increase targeted traffic generating higher ad revenue, or to gain a commission for every user visiting there. Although it might appear harmless, these tools are made by malicious people who always try to take full advantage of you, so that hackers can earn money from your naivety and distraction. What’s more, hijackers can make the whole infected system fragile – other destructive malware and viruses will take hold of these opportunities to get into your computer system effortlessly.

How to know whether the browser is hijacked?

Symptoms that your internet browser is hijacked include: 1. your home page has been reset to some unknown webpage 2. bookmark and the new tab are also changed 3. default web engine is changed 4. you see unwanted new toolbars added 5. you’ll notice random pop-ups start showing regularly 6. your web browser starts running sluggishly or exhibits frequent glitches 7. Inability to navigate to particular sites, particularly anti-malware as well as other computer security software webpages.

How it infects your PC

Browser hijackers infect PCs in numerous ways, including via a file-share, a drive-by download, or an infected email. They can also be deployed via the installation of an internet browser toolbar, extension, or add-on. Also, certain shareware and freeware can put the hijacker in your PC through “bundling”. Browser hijackers can record user keystrokes to collect potentially invaluable information that leads to privacy issues, cause instability on systems, drastically disrupt the user experience, and ultimately slow down the PC to a point where it becomes unusable.

Tips on how to get rid of browser hijackers

Certain kinds of browser hijackers can be removed from your computer by deleting malicious applications or any other recently added freeware. Often, it can be a tough task to find and eliminate the malicious component because the associated file might be running as part of the operating system process. Also, manual removals require in-depth system understanding and thus can be a very difficult task for beginner computer users. Professionals always suggest users remove any malicious software including browser hijacker by using an automatic removal tool, which is easier, safer, and quicker than the manual removal process. Safebytes Anti-Malware detects all kinds of hijackers – including FoxTab – and eliminates every trace efficiently and quickly. Employ a pc optimizer along with your antivirus software to solve various computer registry problems, eliminate system vulnerabilities, and boost your computer performance.

Malware Blocking Access To Safebytes Website And Anti-Malware Downloads - What You Should Do?

How to Fix Remote Desktop Black Screen issues

According to some reports, using RDP or Remote Desktop Protocol on recent versions of Windows 10 results in a black screen. One encounters this issue is when using the Remote Desktop Connection feature on Windows 10. The real causes of this black screen are either the display drivers or some misconfiguration with the Remote Desktop Connection utility. In most cases, the Remote Desktop in Windows 10 will display a black screen and then disconnects afterward. To fix this kind of issue on your Remote Desktop, there are two suggestions you need to check out. First, you can try to disable the persistent bitmap caching, and then you can also try to update your display driver. Follow the given options below for more troubleshooting instructions.

Option 1 – Try to disable Persistent Bitmap caching

The first thing you can do to resolve the black screen issue with the remote desktop is to disable the persistent bitmap caching. All you have to do is follow these steps:

First, open the Remote Desktop Connection client.
Next, click on the Show Options button to configure the Remote Desktop Connection.
After that, go to the Experience tab and uncheck the Persistent bitmap caching option.
Once done, you should now be able to connect to the remote computer without the black screen.

Option 2 – Try to update or rollback the Graphics driver

You can try to update your Graphics card driver using the Device Manager in your computer to resolve the blank dialog boxes problem or you can also go directly to the website of your graphics card manufacturers like NVIDIA, Intel, or AMD and go to the section called Drivers then check if there’s a new available update – if there is, download and install it. To update your Graphics driver via Device Manager, refer to these steps:

First, boot your computer into Safe Mode.
After that, tap the Win + R keys to launch Run.
Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
After that, a list of device drivers will be displayed. From there, look for the Display Adapters and click on them.
After that, right-click on each entry under the Display Adapters and select the “Uninstall Device” option from the menu.
Now restart your computer.
After restarting your computer, go to the Settings app and Check for Updates in the Windows Update section.

Note: If updating the Graphics driver didn’t fix the problem, you can also try to roll back to its previous version and see if that helps or you could also try to roll back, update or reinstall the Network Adapter drivers.

Option 3 – Try performing a System Restore

You might also want to perform a System Restore that might help you in fixing the error. You can do this option either by booting into Safe Mode or in System Restore. If you are already in the Advanced Startup Options, just directly select System Restore and proceed with the next steps. And if you have just booted your PC into Safe Mode, refer to the steps below.

Tap the Win + R keys to open the Run dialog box.
After that, type in “sysdm.cpl” in the field and tap Enter.
Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

Finding out which GPU is in your computer

Every computer has to have a graphic card, it is one of the essential components in order for the computer to work. If you have a second-hand computer, got one as a gift, or similar, there is a high chance that you do not really know which components are inside. Luckily finding out which graphic card you have inside is quite easy. Right-click the taskbar and select Task Manager Click the Performance tab at the top of the window, if you don’t see the tabs, click “More Info.” Select “GPU 0” in the sidebar. The GPU’s manufacturer and model names are displayed at the top right corner of the window. You’ll also see other information, such as the amount of dedicated memory on your GPU, in this window. Windows 10’s Task Manager displays your GPU usage here, and you can also view GPU usage by application. If your system has multiple GPUs, you’ll also see “GPU 1” and so on here. Each represents a different physical GPU.

Fix The update isn’t applicable in Windows

There are times when you install a Windows update to your Windows 10 computer but you only got an error message saying, “The update isn’t applicable to your computer”. This is unusual as Windows was the one that downloaded them in the first place. To understand the reason behind this error, read on as this post will also give you a couple of suggestions you can try to fix the problem. One of the main reasons why this error occurs is that your computer might not have the required installed updates and many more. Other reasons include:

The update might be replaced. There are instances when a newer Windows version is already available on the computer and that the version you are trying to manually install is an older version which is why the Windows update failed.
The update might already be installed. There are times when the update process is still in progress and the earlier payload might have already been installed.
It could also be that it’s a wrong update for architecture. As you know, updates are designed accordingly based on the architecture of the computer so if the update you are trying to install does not match the architecture of your CPU then it’s no wonder you’re getting an error message.
Your computer might be missing a prerequisite update. There are Windows updates that depend on other updates so if you missed one and you’re installing another one, it could be the reason why you’re getting the error.

To fix the problem, here are some suggestions that might help.

Option 1 – Try verifying the package and the Processor Architecture

As pointed out earlier, updates are made according to the Windows versions. Thus, if one of the updates failed to install, you need to check if it’s applicable or not. The best way to do that is by searching the Windows update name on the official website of Windows. It could be that the Processor Architecture is not compatible with the Windows Update you are trying to install. If you have an X86-based processor, you can’t install x64-based installations of Windows and vice-versa. This usually happens when you’ve downloaded the update manually and then tried installing it.

Option 2 – Try checking if the update is old

The issue might be because you are trying to install an old Windows update which is why it didn’t work. To check, go to Settings > Update and Security > View Update history. From there, you can look for the update.

Option 3 – Try checking if the update is already installed

To verify the update, just go to the Windows Update history once more as you did in option 2, and then see if the update is already installed or not.

Option 4 – Try checking the prerequisites

AS mentioned earlier, there are some updates that depend on other updates before they get installed on your computer. The best way to verify is by checking the Microsoft Knowledge Base (KB). And to verify if the prerequisite updates are installed or not, just run the command below in PowerShell:

get-hotfix KB1111111, KB2222222, KB3333333

Note: In the command given above, you need to replace “KB1111111, KB2222222, KB3333333” with the actual update KB numbers.

Option 5 – Try running the Windows Update Troubleshooter

As you know, Windows 10 has various auto-repair built-in tools to help users fix small issues which used to get fixed manually. And in this case, you will need the Windows Update Troubleshooter to fix the issue.

Go to Settings and click on Update and Security.
From there, click Troubleshoot and click on Windows Update and then click the “Run the troubleshooter” option.
After that, it will try to detect and automatically fix common issues in the Windows Updates which can be resolved by Windows itself. Note that the process may take several minutes before it completes so you need to wait until it’s done. Once it’s done, in case you have some pending update that wasn’t realized by the system early on, it will apply the fix right away and restart the Windows Update service.

How to Fix ntdll.dll crash Error on Windows

DLL files, also known as Dynamic Link Libraries are external parts of applications that run on Windows as well as other operating systems. Almost all applications are not complete in themselves and store code in different files. In this post, we will be discussing one DLL file called ntdll.dll. It is described as “NT Layer DLL” which means that it contains some Kernel functions that help in the normal functioning of the Windows operating system. It is created by Windows in the System32 folder when the OS gets installed. This file can serve different programs simultaneously by providing them with different Kernel functions which support the programs’ performance. However, if you encounter the ntdll.dll file error on your Windows 10 computer, read on as this post will guide you in fixing the problem.

Option 1 – Try to re-register the ntdll.dll file

You may have to re-register the ntdll.dll file using the regsvr32.exe before you can successfully install the program and fix ntdll.dll file crash error. The Regsvr32 tool is a command-line utility that can be used to register and un-register the OLE controls like DLL and ActiveX (OCX) control in the Windows operating system. Follow the steps below to use it.

Open Command Prompt as admin from the WinX menu.
Next, type the following commands in the elevated Command Prompt and hit Enter to execute the command. This will re-register the affected DLL file using the Windows operating system tool, regsvr32.exe.
- exe /u ntdll.dll
- exe ntdll.dll
You should see a message saying, “DllRegisterServer in vbscript.dll succeeded” if the Regsvr32 tool was able to run successfully. After that, try to install the program again and see if it now works.

Option 2 – Disable problematic Internet Explorer add-ons

There are instances when some add-ons in the Internet Explorer browser can cause the ntdll.dll file crash error. Thus, you need to disable some add-ons in Internet Explorer and then check if it fixes the problem.

Option 3 – Try running the DISM tool

You might want to repair potentially corrupted files in your system as having them could also trigger the ntdll.dll file crash error. To repair these corrupted system files, you can run the DISM commands:

Tap the Win + X keys and click on the “Command Prompt (Admin)” option.
After that, input each one of the commands listed below sequentially to execute them:
- Dism /Online /Cleanup-Image /CheckHealth
- Dism /Online /Cleanup-Image /ScanHealth
- Dism /Online /Cleanup-Image /RestoreHealth

Once you’ve executed the commands given above, restart your computer and check if the DCOM error is now fixed.

Option 4 – Try to run the Program Compatibility Troubleshooter

You might also want to run the Program Compatibility Troubleshooter. This built-in troubleshooter is available in the Windows Update & Security section. From there, select Troubleshoot. This will find a list of programs for you and since you have already downloaded the driver files, just click on Not Listed located at the top of the program list. After that, browse and select the driver files and then let the program do its job.

Option 5 – Try to replace the DLL file with a trusted source

First, you need to get the new DLL file from another computer with preferably the same file version number.
After that, you need to boot your PC into Safe Mode and navigate to the paths listed below and then replace the file using a USB drive or other external storage devices.
- x86: This PC > C:WindowsSystem32
- x64: This PC > C:WindowsSysWOW64
Next, type “cmd” in the Cortana search box and right-click on Command Prompt, and select “Run as administrator” to open it with administrator privileges.
Now type the “regsvr32 ntdll.dll” command and hit Enter.
Restart your PC and check if the error is now fixed.

Option 6 – Try scanning your computer using Windows Defender

The ntdll.dll file crash error might also be infected with malware or virus and to eliminate it, you have to scan your computer using security programs like Windows Defender.

Tap the Win + I keys to open Update & Security.
Then click on the Windows Security option and open Windows Defender Security Center.
Next, click on Virus & threat protection > Run a new advanced scan.
Now make sure that Full Scan is selected from the menu and then click the Scan Now button to get started.

Being the gamer is now maybe the best time to be, sitting in the comfort of your home, safely isolated from viruses and people, just pushing buttons and emerging yourself in a vast world and new adventures. But games cost money, and sometimes being a gamer can be expensive, also the COVID situation makes it even more difficult to spend some time with friends. Do not worry, we are here to help. I am presenting you the list of MMO games that you should try or play during this COVID Winter, and since they are MMO games, you can play them with your friends and hang out in the virtual world. Some of them are also free to play so they will not cost you any money to enjoy them. The following list is not set in any particular order and remember that this is not a ranked list. There is no best MMO and I will not try to place any of these titles as one dominant, I will just point their style and who they might be for, it is up to you to decide which one you will pick and enjoy.

Best MMO’s in no particular order

EVE Online

EVE Online is one of the earliest MMO games out there but since its release, it is still actively developed and is receiving updates. This science-fiction Sandbox will offer space lovers everything they need and more. Large scale PvP, mining, pirating, etc. It can be daunting and complex for beginners but take your time to get familiar with its systems and you will be rewarded greatly with an immersive and complex game worth the time. Open PvP in some zones might not be everyone’s cup of tea and seeing only your ship might be a turn-off for some players, but if you do not mind these things give it a go. It is free to play with an item shop.

Final Fantasy XIV

FF14 had a tough start, so tough that it was scrapped and destroyed and has been remade again and that idea was great. The game now is better than ever and at this time it is experiencing large players from other games surging into it. This on the rails fantasy MMO will offer you a great story and great leveling experience. It has a free trial where you can play the whole original game for free but if you wish to continue playing you will have to buy the expansion and pay a monthly subscription but the content is well worth the money.

World of Warcraft

Let’s be honest, not a single list of MMO games cannot be without a once greatest and most successful MMO ever made, World of Warcraft. But instead of me praising the game why it was the greatest and why you should play it and how great it is I am going to take a little different approach. I am going to recommend you World of Warcraft classic, yup, you read it correctly, classic. Now World of Warcraft is a retail game with a subscription service but with that one subscription you will be able to access three games in the World of Warcraft universe: World of Warcraft retail (standard game), World of Warcraft Classic (vanilla WOW without expansions offering you experience as it once was when it was released) and World of Warcraft the Burning Crusade classic (same as WOW classic but with the first expansion the Burning Crusade). Among all solutions, I would really urge you to play either WOW classic or WOW TBC classic simply for reason that they are far superior games in comparison to typical retail ones, but if you like easier game go for retail, it is included in the sub anyway.

Guild Wars 2

Guild Wars 1 was one of my favorite games and I sank a lot of times in it and once Guild Wars 2 came I must admit I was pleasantly surprised with it and I would recommend it highly. The base game is completely free to play with only expansion to be purchased and it is buy to play model without monthly fees. It has specific mechanics different from other games and interesting classes to try. The living world is a great feature of the game and it is still very strong with its player base.

Star Wars: old republic

This game is made for people who enjoy, love, and like Star Wars. Mechanically besides being able to have henchmen with you and space battles (which I do not really like how they are done) game itself does not offer anything special. Where it shines is in the story and overall Star Wars experience. If you look at this game as a single-player game with multiplayer dungeons you will have a great time, since the story is really good but sadly end game lacks in comparison.

Elder Scrolls Online

Blackwood-release-date-on-TESO-when-will-the-new-chapter

I am going to admit something here, I was not fond of the idea to make the beloved Elder Scrolls series into MMO, but in time I gave it a go and I am really glad I did. This game is great and it is getting better and better as time progresses. It is buy to play without monthly fees and basic game free, same as FF14 but without fees. It has a decent community and offers a really good Elder Scrolls experience and now it is packing Morrowind expansions and other great areas. Highly recommended for any Elder Scrolls fan.

Lord of the Rings Online

This one is troublesome to recommend, on one side you have free to play games deeply inside Tolkien Lord of the Rings lore, on the other side, you have outdated graphics and some stupid item shop decisions like buys specific classes. But if you look past stupid item shop decisions and can live with playing free class in the game you will be pleasantly surprised. The game itself is surprisingly good, the story is great as expected from the game infused with lore taken from one of the best books series ever written, and the feeling when visiting iconic landscape is epic. But if I need to be real as I should, I would recommend this one to people appreciate good story and lore and ones that are fans of Lord of the Rings itself.

Neverwinter

Neverwinter is a premium and licensed D&D MMO game and it is well strange. The free-to-play model of the game will let you enjoy it until you hit the end game, then you will have to shell real money if you want to be competitive but the journey until then is great. I would recommend it to D&D lovers and people that love to try other people's maps, yup you read it correctly. Neverwinter has a map editor making it one of a kind MMO game where you can create your own dungeons and post them for other players to play, this user-generated content makes it a very specific beast in this list, and for that feature alone it has my recommendation.

Tera

Another one of the older titles, Tera will offer you nor depth nor anything new in terms of leveling, quests, or end game except… the COMBAT. This is maybe the greatest MMO Combat game ever created and it is quite fascinating that even after so many years no other game has managed to create a better combat system than one of Tera. If you enjoy action combat and like some specific aesthetics Tera is a game for you.

Albion

Albion is a sandbox game with open-world PvP and building mechanics where you can build your own forest, house, etc. You know, sandbox stuff, including a lot of crafting and well, other sandbox stuff. If you want great quests and some occasional play then skip Albion, this game is made for a more hardcore player base not being afraid to die and spend some time crafting and going through the economy. The best comparison might be with EVE but in fantasy settings.

Black Desert

Black Desert is also a sandbox game but different from Albion, here you can organize and hire a workforce and send them to different nodes on a map to harvest resources and build an economy while you are on some epic adventure. Housing is also included but you can buy already made houses instead of making your own in the world. Combat is a game that comes very close to Tera combat and it is very enjoyable. The end game is money sink and PvP based so be careful when choosing this one.

Secret World Legends

the-secret-world-relaunching-as-1200x675

If you like occult and supernatural with new world order themes and conspiracy theories, Secret World Legends is the game for you. Somewhat little clunky its setting and story really set it apart in many many ways. It has semi-action combat and it is free to play with item shop but all the content can be experienced for free. Recommended for fans of deeper gameplay and horror lore.

Runescape

When I said no MMO list can be without World of Warcraft, it also cannot be without Runescape, one of the oldest games it was revamped with newer mechanics and graphics, free to play all the way and you can also pick old school Runescape if you really want to go all the way on a nostalgia trip. I would recommend a newer one for newer players, the game offers a great story and unusual quests infused with puzzles and interesting storylines. If you like really good quest design without fetch and grind quests along with interesting story this is a game for you.

AION

Last on my list would be AION, a very interesting game made also a long way back, but the fact that is completely free with the cosmetic shop will make it as one to recommend since you can experience the whole game for free. It has some limited flying mechanics in it and later game zone are open PvP zones, story is interesting and leveling process is enjoyable. Also game itself is not really easy and if not careful you can get yourself in danger quite quickly. Recommended for old-school feeling.

Conclusion

That's it, there are many more MMO games out there but some are on verge of closing down and some are plainly bad. I hope that I have made your choice easier and that you will find one or a few from this list to spend your time in it. Remember, stay safe and take care of yourself.

Fix fatal error C0000034 applying update

Fatal error C0000034 happens during the installation of the Windows update and if you are one of the unlucky users who sadly run into this, keep reading as we will provide solutions to this error and how to get around it. Start from point 1 to the bottom and hopefully you will have your PC back into working order in no time.

Run Windows Update troubleshooter
Usually, a built-in Windows troubleshooter can solve issues painlessly and fast, my advice is to try this as the first option, it is a simple and clean solution worth trying and in 90% it solves the issue all by itself.
Do a clean boot
Using task manager, remove all nonessential applications and services from starting up, reboot your computer, and once it is cleanly booted try re-running the update process again, if the issue was running the application this time everything will work since the problematic application is not running.
Reset Windows update components to the default
This solution requires you to use the Reset Windows Update Agent Tool to reset Windows Update components to default or use this PowerShell script to reset Windows Update Client. You can also manually reset each Windows Update component to default and then re-run the update.
Disable firewall and antivirus
Altho not likely it is still a possibility that some firewalls and antivirus can detect windows updates as malicious software and cut them off. If everything else failed, disable the firewall and your PC protection and when it is fully disabled try updating.
Do automatic startup repair
This should be the last thing to do but if everything else failed, do it. Perform Windows 10 Startup Repair. Once the startup repair completes successfully, you can re-run the update. The update should install without errors.

Merge or Delete an OEM Partition in Windows

OEM Partition, also known as System Reserved Partition, is placed by the OEM to help users recover their computers or bring back the original state of the computer when it was bought. If you’ve observed that a part of your hard drive says “Healthy (OEM partition)” in the Disk Management and it occupies space in GBs, then this means that it’s normal and there’s nothing to worry about except that part of the storage space is not available and even when you right-click on it, the only thing it displays is the Help menu. Thus, in this guide, you will be guided on how you can merge as well as delete an OEM partition in your Windows 10 computer. Since the Disk Management tool in Windows won’t let you merge or delete the OEM partition, you can just use the built-in command-line tool known as Diskpart. Note that you have to be extra careful when you run the commands as it could mess your computer up and before you proceed with the instructions provided below, make sure that you create a System Restore point first. Once you have that covered, follow the instructions below. Step 1: Tap the Win + R keys to open the Run dialog box and type “cmd” in the field and tap Enter to open the Command Prompt. Step 2: Next, execute this command to launch the Diskpart tool: diskpart Step 3: Execute this second command to view the list of the disks in your computer: list disk Step 4: Now select the disk you want to manage by executing this command: select disk x Note: In the command above, replace “x” with the letter of your disk. Step 5: After that, execute this command to display all the volumes or partitions: list partition Step 6: Now execute this command to select the partition you want to delete: select partition x Note: You have to replace “x” with the partition you want to delete. Step 7: Once done, execute this command to delete the selected partition: delete partition override Step 8: Afterwards, execute this command to merge the OEM partition with the adjoining value: Extend Note: if you only want to merge part of the partition, you need to use this command “extend [size=<size>]”. For instance, you want to extend its size by 5GB, then you need to type “Extend size=5000”. The size you set is the size you select from the OEM partition. This will extend the selected volume by size in MB or megabytes.

Some Steam tips and tricks for easy life

Steam has cemented itself as the largest digital game shop in the World. First, release all the way back on September 12^th, 2003, it was meant to be a standalone software client aimed to deliver updates to Valve’s games. It was soon expanded to include titles from third parties. The greatest Steam expansion and its popularity started in 2004 with the release of Half-life 2. Steam allowed prepurchased editions to be downloaded before the official release of the game making it available for play the moment it was officially out. Very soon after Steam gained its popularity, Valve has opened doors to other developers and offered them to use Steam as means for a digital distribution platform. Today it hosts over 30000 different game titles, not including DLC or applications. And how soon Valve’s steam deck is coming out soon we would like to share some great tips and tricks about Steam itself for easy everyday gaming.

Steam guard account security

Security of any of your accounts should be something that you really take seriously. So as always use a strong password for Steam but if you want an extra layer of security for it, and you should, use the Steam built-in feature: Guard Account Security. In order to activate Security Guard go to Steam>Settings>Account>Manage Steam Guard Account Security. Once enabled you will be able to use the Steam mobile application for special code when opening Steam or your email address.

Use Steam beta feature

Once a Steam account is created by default you will download and install the client. In the client, you will have the latest features available but there are more Steam features than default ones, beta features that can offer some improved and new functionality, and do not worry, they are stable and bug-free. I have been in Steam beta for years and not even once have I had any issues with the client itself but I have always had the latest features that will come to regular users later. To enable beta participation to go to Steam>Settings>Account, open the drop-down Beta participation menu, and choose Steam Beta Update. Confirm on OK and restart the Steam client. You will now get all the latest features first.

Manage your library via Collections

The collection is a neat idea for organizing your large game library into different collections or sections easily expanded and contracted for easier navigation and organization. To add the game to a collection just right-click on it and select Add To>New Collection, make a name for a collection like action, RPG, or whatever rocks your boat, and you are done. Once the collection is created other games can be added to it simply just by dragging it into the desired collection.

Make shelves

Shelves are ways to see your collections in the larger areas of the Steam clients. By clicking Add Shelf>Choose a Shelf, you can now add your collection to a shelf on the larger part of the client as a horizontal scrolling container with your chosen games. There are also some predefined shelves like All Games, Recent friend activity, and more.

Hide Game from Library

By right-clicking on a game and selecting Manage>Hide This Game you will remove the game from the active view of your Steam library. Note that the game will still be owned and a part of your library, you will just not be able to see it. This is a great feature when for example you have some things that came as a part of the game pack you are not really interested in when you have 2 different versions of the same game as for example standard and deluxe edition or just by simply not wanting to have game visible in the library. You can find a hidden game by typing its name in the search box and from there you can unhide it.

Play game soundtracks inside Steam

Some games offer you to purchase their soundtracks if you like music from them and some even include OST with a regular purchase. Steam lets you play these soundtracks and even lets you import your own music library folder into it in order to play all of your music inside the client itself. It has even options to automatically stop music playing once the game is run and you can make playlists as well. Your purchased game soundtracks are automatically included, the rest you will need to add by pointing Steam to the folder where you keep music in.

Configure gamepad

Inside Steam, you can configure your gamepad’s general settings, big picture settings, desktop settings, etc. Steam embraced the idea that many OC users these days own and play with gamepads so it has implemented configuration options inside it. To configure your pad go to Steam>Settings>Controller.

Use big picture Steam mode

Big picture mode is Steam's idea of making Steam an entertainment center. Once it is activated it switches from the application into full-screen mode aimed at large TV screens or monitors. You can easily navigate through it via gamepad, mouse, keyboard, or other devices. You have access to the store, your game library, etc. Same as your typical steam app but a little different. You can easily activate it via View> Big Picture Mode and see for yourself is this something you prefer over a standard application layout.

Enable Steam Cloud

Steam Cloud is a great feature that uses cloud storage to save your game progress meaning that you can easily switch to another PC, install games there and continue where you have left off. Many games support this feature instead of keeping saves locally and it is a great feature worth turning it ON. To turn and use Steam Cloud service go to Steam>Settings>Cloud>Enable Steam Cloud Synchronization. Just remember to check does game you are playing supports this option.

Share your Games via Family sharing

Family sharing is a Steam feature allowing you to share your game library with up to 5 accounts on up to 10 different devices. This is a great way to let other members of your family or even close friends enjoy some games you have or vice versa. They will get as well their own save games so you can sleep safe knowing that your progress can not be changed or hindered. Family sharing can be turned ON by logging into PC Steam client where you would like to share your library and navigate to Steam>Settings>Family and then clicking on Authorize Library Sharing On This Computer.

Refund a game

Sometimes the game is not the same as advertised, sometimes it will not work on your PC, sometimes hardware specifications are too high making the game unplayable, etc. For whatever reason, you might have Steam offers you a full game price refund if you wish to do so, you only need to meet 2 criteria, the game must have been purchased within 2 weeks period, older purchases cannot be refunded, and your game playtime must not be over 2 hours of game time. If you fit into this category all you need to do in order to get the full money back is going to Help>Steam Support, pick a recent game from the eligible list, and ask for a refund.

Gift a game

As you can buy gifts for your friends or loved ones in real life, Valve made sure you can do it in digital as well. Gifting game via Steam is simple and straightforward. Choose a game you wish to gift, go to your shopping cart and instead of clicking Purchase for myself, click on Purchase As a Gift, from there you will be taken to your friend list to choose to whom you would like to gift a game along with the option to write a little note to the receiver like happy birthday, enjoy or whatever.

Stream games in Steam itself

Although Steam is not there yet in streaming as Twitch or Facebook gaming is, there is an option to stream your game sessions on it. Click on Steam>Settings>Broadcast to make all adjustments and start streaming. You can also watch streams from your friend list and Steam is now broadcasting popular streams directly to its client if you want to watch it.

Take a game screenshot

By pressing F12, you can take a screenshot from any game and save it inside your Steam cloud library. You can change of course this default screenshot key via Settings>In-Game and if you would like to see your screenshots you can always do it under View Screenshot Library on a game’s page. That’s it, our Steam tips and tricks for easy and good gaming life, I hope to see you soon on errortools.com for your daily articles, tips, and tricks.

New toys in new PowerToys for Windows

A new update to popular Microsoft PowerToys has brought a few new features that are aimed at speeding up the workflow.

The first new feature that was slid in is Always on top utility. With this cool utility, you can keep the window as the name suggests, always on top of other windows. To enable this cool feature all you have to do is press the key combination of ⊞ WINDOWS + CTRL + T and an active window will be now always on top of all other windows. To reverse and unlock this window from being always on top just press key combination again. A second new feature is a really great one and my favorite thing to happen in power toys. Often we are making the search in our browsers to find stuff, things, maybe some explanations, information, etc. The newest update in power toys brings this to a whole new dimension. While you are on PC you just simply need to type ?? followed by questions like: ?? When doctor strange 2 is coming out and that will launch your default browser with your chosen search engine and provide you with the answer. Third and final thing is G-code support in the file explorer preview pane and thumbnails, meaning that if you work with CNC equipment you can now have a thumbnail preview of the code itself inside File Explorer. And that’s it for now, thank you for coming and reading, Take care and I hope to see you next time.
