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.

An Easy Guide to Fixing Internal Error 2503

Internal Error 2503 - What is it?

Internal Error 2503 mostly pops up on Windows 8. It occurs when you try to uninstall or install software on Windows 8. The error code message may vary and displayed in different formats such as:

The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2503. Called RunScript when not marked in progress The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2503. Called Install Finalize when no installation is in progress

Solution

Error Causes

Some of the most common causes for internal error 2503 are:

Permission not granted to access the Windows Installer Folder
Viruses
Problems with Windows Installer

Further Information and Manual Repair

To repair this issue on your PC without any professional assistance, try the DIY methods given below:

Method 1

Internal error 2503 may occur when your account has limited privileges. You don’t have the privilege to use or access the Windows Installer folder. Your inability to access this folder hampers you from successfully install or uninstall the desired program on your PC. To gain access, you need to ensure you have permission.

For this navigate to the C:\windows folder. Here find the installer folder and then right-click and choose properties.
After that click on the security tab and check if the System and Administrator account has Full access permission.
For that make sure the system group option has ‘all’ selected to allow you full permission.

Fix user account is not authorized

If you encounter an error message saying, “The connection was denied because the user account is not authorized for remote login” when you try to establish a remote connection, read on as this post will help you resolve the problem. This kind of error occurs when the targeted host does not allow you to access that system remotely. Based on the error, you are not authorized to log in remotely which means that you need to obtain the correct permission. There are several potential fixes you can try for this error. You can try to check the Remote Desktop Users group or add users to the Security group or check the Remote Desktop Service itself. Refer to the options provided below for more detailed instructions to fix the “The connection was denied because the user account is not authorized for remote login” error.

Option 1 – Try checking the Remote Desktop Users group

You can encounter this error when the Remote Desktop Users group does not have any permission for your user account that you are using to establish a remote connection. Thus, you need to make sure that your user account is a member of the Remote Desktop Users group. How? Refer to these steps:

Tap the Win + R keys on your keyboard and then type “cmd” in the field and tap Enter or click OK to open Command Prompt.
After opening Command Prompt, type the “lusrmgr.msc” command and tap Enter to execute it.
Alternatively, you can also search for “lusrmgr.msc” in the Start Search and once you’ve opened it, select Users and then double click on your user name to open its Properties.
From there, switch from the “General” tab to the “Member Of” tab.
Next, if you can’t see any Remote Desktop Users group under the Administrator, you have to add it. To do that, just click on the Add button.
After that, on the newly opened window, click on the Advanced and Find Now buttons, respectively.
And in the Search results box, double click on Remote Desktop Users.
Now click on the OK button to save the changes made and check if you can now connect to a remote host or not.

Option 2 – Try to add a user to the Security group

You can actually block or allow a user from logging on through the Remote Desktop Services. However, if you do not have the right setting, you won’t be able to use this functionality. Thus, you need to confirm this setting. To do that, follow the steps below.

In the Start Search, type “secpol.msc” in the field and tap Enter to open the Local Security Policy panel.
From there, go to User Rights Assignment.
Next, look for a policy named “Allow log on through Remote Desktop Services” located on your right-hand side and then double click on it to open its Properties.
If you were not able to find the Remote Desktop Users under Administrator, then you have to add it by simply clicking on the Add User or Group button.
After that, enter “Remote Desktop Users” in the blank field and click the OK button to save the changes made.
Now restart your computer and try connecting again to the remote host.

Option 3 – Try checking the Remote Desktop Users group

There is a service that’s supposed to be running and needs to be set up correctly for you to connect to the remote host. And so you need to ensure that this service is up and running. To do so, follow these steps:

Tap the Win + R keys to launch the Run utility.
Then type “services.msc” in the field and hit Enter or click OK to open the Services Manager.
Next, look for the Remote Desktop Services and double click on it to open its Properties.
After that, go to the “Log On” tab and select the “This account” option and then click on the Browse button.
On the next screen that appears, look for the Advanced button and click on it and use the Find Now button to search.
You will see “NETWORK SERVICE”. Double click on it and then save the changes you’ve made to the settings.
Finally, restart your PC and see if the problem is now fixed.

Automatically Adjust Active Hours in Windows

In case you didn’t know, the new Windows 10 v1903 has brought tons of new features around Windows 10 Updates. One of these features is the ability to automatically adjust the Active Hours based on your computer activity. This feature is really useful as it tells the operating system when to install the Windows Updates. A lot of users use the Active Hours feature to ensure that the Windows Update won’t force them to restart their PCs to install the update. So if your computer is turned on, it won’t apply the update during the active hours you’ve specified. In addition, the active hours change for many users and they are not that strict. For instance, if you set the active hours between 10 am to 5 pm, Windows Update won’t be forcing you to restart your computer to install the updates at those times. Note that Windows Update allows enabling an option using where it can monitor the active hours in your computer and change it. To configure this setting, here’s what you have to do:

Frist, go to Settings > Update & security > Windows Update.
Next, take note of your current active hours and click on the “Change active hours” link.
Then toggle the option that says, “Automatically adjust active hours for this device based on activity”. This will change the active hours and if you match it with the previous one, it should be different.

As you can see on the image given above, the earlier active hours were between 8:00 to 17:00 and were changed to 11:00 to 19:00. If you have been using this feature for a while you’ll find how useful and handy it is especially when you’re using your computer and don’t want any notifications like the prompts for Windows Updates to bother you while working.

Jzip PUP Easy Removal Tutorial

jZip is a software utility published by Bandoo Media and is classified as a Potentially Unwanted Program. The software is an archive tool that used to compress and extract files in the rar, zip, and other formats. The program is typically bundled upon installation with other unwanted applications and is itself often installed in co-bundles. As of publication time, over 40 AntiViruses have flagged jZip as malicious or potentially unwanted.

It injects itself in Windows shell, providing quick access to the program by right-clicking on any file. jZip displays it's advertising in your browser, instead of the default search results, to better do this, it collects information about your browsing history and your current browsing session, so it can better target ads. This software, upon install, defines an auto-start registry key in your system, this allows the software to launch every time your computer is rebooted, no matter what Windows account you log in to, it also adds Windows Tasks, to allow it to launch by itself at random times, even when closed.

About Potentially Unwanted Applications

If you have ever downloaded software programs from the internet (shareware, freeware, etc,), odds are high you’ve unintentionally installed unwanted programs on your personal computer. Potentially Unwanted Programs (PUP), also referred to as Potentially Unwanted Applications (PUA), are applications that you never wanted in the first place and quite often come bundled with freeware software. Once installed, most of these applications can be hard to remove and become more of a nuisance rather than a necessity. The idea of PUP was actually coined to define this crapware as something other than malware. The primary reason for this is that most PUPs get into users’ computers not because they exploit security vulnerabilities, for instance, but because the users grant consent to install it – unwittingly in many instances. Nevertheless, there isn’t any doubt that PUPs are still bad news for PC users as they could be incredibly damaging to the computer in lots of ways.

What do PUPs do on your computer, precisely?

The unwanted programs after installation display a lot of annoying pop-up advertisements create fake alerts, and quite often it even pushes the end-user to buy the software. PUPs which come as browser add-ons and toolbars are widely identifiable. Not just they needlessly take up space on your computer screen, toolbars could also manipulate search results, monitor your browsing activities, decrease your internet browser’s overall performance, and slow your net connection to a crawl. They might seem innocent but PUPs tend to be spyware. The worst part of setting up a PUP is the spyware, adware, and keystroke loggers that might lurk inside. Even if the PUPs aren’t inherently malicious, these programs still do absolutely nothing good on your PC – they will take valuable system resources, slow down your computer or laptop, weaken your device’s security, and make your PC more susceptible to trojans.

Some tips on protecting yourself from unwanted software

• Read the EULA meticulously. Look for clauses that say that you have to accept advertisements and pop-ups or bundled programs from the company. • Typically, when setting up a program you will get two options, ‘Standard Installation (recommended)’ and ‘Custom Installation’. Don’t pick ‘Standard’ as unwanted programs will automatically be installed that way! • Have a solid anti-virus program such as Safebytes Anti-Malware that will protect your personal machine from PUPs. Once you install this software, the defense against viruses and PUPs is already switched on. • Avoid installing freeware software you will not utilize. Turn off or get rid of toolbars and internet browser extensions you don’t really need. • Only download programs from the original providers’ websites. Avoid download portals since they use their own download manager to bundle extra programs along with the initial download.

Can't Install Safebytes Anti-malware because of a Virus? Do This!

Malware may cause several kinds of damage to computers, networks, and data. Some malware types alter browser settings by including a proxy server or change the computer’s DNS configuration settings. In such cases, you will be unable to visit some or all of the websites, and therefore unable to download or install the required security software to clear out the infection. So what to do if malicious software keeps you from downloading or installing Safebytes Anti-Malware? Follow the instructions below to eliminate malware in alternate ways.

Make use of Safe Mode to fix the issue

In Safe Mode, you are able to modify Windows settings, un-install or install some software, and eliminate hard-to-delete viruses. In case the virus is set to load immediately when the computer starts, switching to this particular mode may well prevent it from doing so. In order to get into Safe Mode or Safe Mode with Networking, press the F8 key while the system is booting up or run MSConfig and find the “Safe Boot” options in the “Boot” tab. After you restart the PC into Safe Mode with Networking, you may download, install, and update the anti-malware program from there. After installation, run the malware scanner to remove most standard infections.

Download the security program using an alternate internet browser

Web-based viruses can be environment-specific, aiming for a particular web browser or attacking particular versions of the browser. The most effective solution to avoid this issue is to opt for an internet browser that is known for its security measures. Firefox contains built-in Phishing and Malware Protection to help keep you safe online.

Create a portable USB antivirus for eliminating viruses

Another solution is to save and run an anti-malware software tool completely from a USB drive. Adopt these measures to employ a USB drive to clean your corrupted system. 1) Download Safebytes Anti-Malware or MS Windows Defender Offline onto a clean computer. 2) Plug the Flash drive into the uninfected computer. 3) Double-click the exe file to open the installation wizard. 4) When asked, choose the location of the USB drive as the place in which you want to store the software files. Follow the activation instructions. 5) Now, plug the thumb drive into the corrupted PC. 6) Run the Safebytes Anti-malware directly from the pen drive by double-clicking the icon. 7) Run Full System Scan to detect and clean-up up all kinds of malware.

Technical Details and Manual Removal (Advanced Users)

If you wish to manually remove Jzip without the use of an automated tool, it may be possible to do so by removing the program from the Windows Add/Remove Programs menu, or in cases of browser extensions, going to the browsers AddOn/Extension manager and removing it. You will likely also want to reset your browser. To ensure the complete removal, manually check your hard drive and registry for all of the following and remove or reset the values accordingly. Please note that this is for advanced users only and may be difficult, with incorrect file removal causing additional PC errors. In addition, some malware is capable of replicating or preventing deletion. Doing this in Safe Mode is advised.

VideoDownload Converter removal guide

Video Download Converter is a potentially unwanted toolbar distributed by Mindspark Interactive network. This toolbar offers users the ability to download and convert youtube and other online videos.

While this may seem useful at the start, this toolbar monitors user browsing activity and records visited websites, clicked links, and even personal data, that it later uses to display injected ads through your browsing session. When the toolbar is installed, it will automatically hijack your home page and search engine setting them to MyWay.com. This search engine uses google to display your search results, however, it injects ads into the search results to generate ad revenue. Several anti-virus scanners have detected VideoDownloadManager as a Browser Hijacker, and are therefore not recommended to keep on your computer.

About Browser Hijackers

Browser hijacking is actually a form of unwanted software, commonly a browser add-on or extension, which then causes modifications in the browser’s settings. There are lots of reasons why you might experience a browser hijack; however commercial, marketing, and advertising are definitely the key purposes for their creation. Usually, it will force users to predetermined sites which are looking to increase their advertising campaign earnings. It may seem naive, but the majority of these sites are not legitimate and can pose a major threat to your online safety. Browser hijackers can also allow other harmful programs without your knowledge to further damage the computer. How to determine if your browser has been hijacked There are many symptoms that indicate the internet browser has been hijacked: the home page of your browser is changed suddenly; you find yourself constantly directed to a different web page than the one you intended; the main web browser settings are modified and unwanted or insecure resources are added to the trusted websites listing; unsolicited new toolbars are added to your web browser; you may find numerous pop-up adverts on your computer screen; your browser has instability issues or exhibits frequent errors; you can’t navigate to certain websites, such as computer security software related websites.

So how does a PC get infected with a browser hijacker?

Browser hijackers can enter a PC by some means or other, for example via file sharing, downloads, and e-mail too. Many web browser hijackings originate from add-on applications, i.e., toolbars, browser helper objects (BHO), or extensions added to browsers to provide them additional features. Some browser hijackers spread in user’s computers using a deceptive software distribution method called “bundling” (commonly through freeware and shareware). Some of the popular hijackers are VideoDownload Converter, Babylon Toolbar, Conduit Search, OneWebSearch, Sweet Page, and CoolWebSearch. Browser hijackers might record user keystrokes to gather potentially invaluable information leading to privacy concerns, cause instability on computers, drastically disrupt user’s browsing experience, and eventually slow down the PC to a point where it becomes unusable.

The best ways to remove browser hijackers

Certain kinds of browser hijackers can be easily removed from your PC by uninstalling malicious software programs or any other recently added shareware. However, many hijacking codes are not very easy to get rid of manually, since they go deeper into the operating system. Moreover, manual removal demands you to do many time-consuming and complex procedures which are very difficult to carry out for beginner computer users. You can go for automatic browser hijacker removal by simply installing and running reliable anti-malware software. Safebytes Anti-Malware has a cutting-edge anti-malware engine to help you prevent browser hijacker infection in the first place, and clean up any pre-existing issues. Together with anti-malware, a PC optimizer tool, similar to Total System Care, could help you resolve registry errors, remove unwanted toolbars, secure online privacy, and improve overall system performance.

Increase or decrease notification display time

As you know, the Windows 10 Action Center has a stack of all the notifications that come from different applications on your computer. So each time an app displays notifications, it will be displayed for about 5 seconds and then it disappears right away. Although the allotted time for the notifications to be displayed is quite enough to catch your attention and help you get a glance at the message, there are times when you might miss it and you hoped it could’ve been displayed a lot longer. So in this post, you will be guided on how you can increase or decrease the display time of the notification in Windows 10. The best way you can view the missed notification is to click on the Action Center. From there, you will see all the notifications that are grouped by the applications. This means that if you have a lot of notifications, it would be hard for you to find what you are looking for. Thus, in such cases, the best way you can do is to increase the display time for which notification to stay on the screen.

To get started, refer to the instructions given below.

Step 1: Tap the Win + I keys to open Settings. Step 2: Next, navigate to Home > Ease of Access > Display. Step 3: After that, scroll down to the end until you see the dropdown to change the notifications where you should see the “Show notifications for”. Step 4: Then you can change the time from the default 5 seconds to 7, 15, 30, and so on. Step 5: Once done, the display time of the notifications should stay longer but keep in mind that you must choose the length wisely so if you have notifications from a lot of apps, then the screen will also be filled with multiple notification cards.

Why you should upgrade your 60Hz Screen

The number of Hertz is the number of how many images your screen draws in one second. So monitor with a refresh rate of 60Hz will draw 60 images each second on your screen. To most users, this will look fine and enough but actually, if you would place them in front of a 120Hz screen difference will be visible right away.

Benefits of higher refresh rates

In most simple words just looking at a screen that has a higher refresh rate will produce a more natural feel of things, although some people would argue that flickering can not be seen on 60Hz monitors and that should be enough, I would argue that they never watched the movie, played the game or used high refresh rate screen when they can state something like that.

Yes, 60Hz might be enough to look at the web page or read some documents but long exposure to 60Hz can have a tiring effect on the eyes in the long run. 120Hz and above just feel more relaxed and it is far less demanding on the eyes. Watching movies also is much better on a higher refresh screen, with way much less motion blur in fast scenes giving the overall experience a greater natural feel.

Gaming is perhaps an area where a refresh rate of 120Hz and above will show its best. Having a higher refresh rate will be easier on your eyes and can even give you a competitive edge. When for example you have twice more images per second on your screen than your opponent his movement will be more fluid and predictable because of that and overall precision will be much higher when moving the cursor in the game since more frames per second means more precision and smoother movement.

The dark side of high refresh rates

After all the positive things that were said about the advantages of high refresh rates, it is just fair to look at some negatives or in this case only negative one and that is Computer power. As said in the previous section having a 120Hz refresh rate means having 120 frames displayed on the screen per single second. Having even higher monitors like 360Hz means even more frames per second and in order to actually see all of that frames you will need to have enough computer power to back it up. Having for example screen with a refresh rate of 240Hz means nothing if your GPU and rest of the computer are able only to push 150 frames per second, in this case, you will still have 150 frames in one second despite the monitor being able to go to 240.

Conclusion

Generally and with all of my heart I would recommend moving away from 60Hz monitors, yes they are cheaper and more affordable but at the end of the day if you are someone like me who spends most of his daily time in front of the computer you would be grateful to have higher refresh rate screen and save your eyes, and after all, why not enjoy some smoother and better movie and game experience as well as saving your eyesight.

How to Fix the File Too Large Error in Windows 10

If you are trying to copy large files that are over 4GB to a USB flash drive or SD card, but you suddenly get an error message saying, “File Too Large, The file is too large for the destination file system”, read on as this post will help you fix this problem. A user recently reported that while trying to copy a 4.8GB zipped file from a Windows 10 PC to a new 8GB USB drive but only got the File Too Large error message instead. If you share the same problem with this user and you know that there is more than enough available space for the file in your USB drive or SD card, continue reading until you get to the instructions provided in this post so that you will be able to copy the file successfully. It is most likely that the USB drive has been FAT32 formatted which is why you’re unable to copy the file and got an error. The FAT32 file system has a built-in limitation on the size of the individual file that it may contain. For instance, it’s 4GB so even though collectively, it may have files or even 1TB individually it shouldn’t be more than 4GB. Thus, you need to change the file system from FAT32 to NTFS. To do that, carefully follow the instructions provided below.

Step 1: Connect the USB drive and open the Windows File Explorer.
Step 2: Afterwards, right-click on the USB drive letter and select Format from the context menu.
Step 3: Next, select NTFS instead of FAT32 the instant a dialog box appears from the drop-down menu for the file system.
Step 4: Now click on the Quick Format option and then click the Start button to reformat the USB drive.

Note: There is also another way you can change the file system. In this alternative way, you need to open an elevated Command Prompt and type the convert X: /fs:ntfs /nosecurity command, and hit Enter to execute it. Remember that in this command, “X” is the letter of your USB drive so whatever the letter of your drive is, you need to make sure to put it instead of “X”. Once the process is completed, try copying the file again.

Removal guide for Movie Mode Potentially Unwanted Program

MovieMode is a Potentially Unwanted Program developed by GenTechnologies Apps that allegedly ads a “Lights Off” function to video streaming websites like Youtube. This feature allows a user to dim the entire background around the video, allowing for better video focus. Although this sounds interesting and useful, upon further inspection it was discovered that this program does not work with modern browsers.

While installed, MovieMode may modify your browser settings, changing your home page, displaying additional ads, and other suspicious behavior. From the Terms Of Use: “Applications may be automatically enabled on your web browsers following installation. Applications or advertisements may require changing your web browser’s default home page, default page, or set of pages on startup, default search provider, and other browser settings. So that Applications can function most efficiently and with the least annoyance, Applications may modify or disable certain web browser or operating system features including, but limited to load time alerts, accelerator features, and Content Security Policy functionality. Applications may also include features to notify you when you are launching an application or visiting a web domain that may interfere with your installed Applications. “

About Potentially Unwanted Applications

What is a Potentially Unwanted Program (PUP)?

Have you ever detected an unwanted program running on your computer and wondered how the heck it got there? These unwanted programs, which are referred to as Potentially Unwanted Programs, or PUPs in short, usually tag along as a software bundle when downloading the program and could cause significant problems for users. From the technical perspective, a PUP is not true “malware”. A basic difference between PUP and malware is distribution. Malware is normally dropped via vulnerability exploitation while PUP gets installed with the consent of the end-user, who knowingly or unintentionally approves the PUP installation on their computer system. On the other hand, it is obvious that PUPs are still bad news for computer users as they could be quite dangerous to the computer in lots of ways.

How do unwanted programs impact you?

Unwanted programs can be found in many forms. Typically, they will be found in adware bundlers that are known to use aggressive and deceptive advertising. Most bundlers install numerous adware applications from various vendors, each of which has its own EULA policy. Safebytes Anti-malware completely eradicates this threat and safeguards your PC against unwanted programs or malware infection. Additionally, most free software programs these days include a few unwanted add-ons; in many instances an internet browser toolbar or browser modification like a homepage hijacker. Not only they needlessly use up space on your screen, but toolbars may also manipulate search results, track your browsing activities, decrease your web browser’s overall performance, and slow down your web connection to a crawl. They could seem innocent but PUPs are sometimes spyware. The worst part of setting up a PUP is the spyware, adware, and keystroke loggers that may hide inside. Most PUPs don’t have any significant value or advantages. As soon as they are installed, they could waste your valuable system resources and also drastically slow down computer performance. Many of these programs are harmful to computer systems and put your private information and perhaps your identity at stake.

The best ways to stop PUPs

• Always study the license agreement and privacy statement. Don’t agree unless you understand exactly what you’re agreeing to. • Always pick the custom if you’re provided a choice between Recommended and Custom Installations – never ever click Next, Next, Next blindly. • Use an ad blocker/pop-up blocker; Install anti-malware products such as Safebytes Anti-malware. These kinds of programs can establish a wall between your computer and online criminals. • Avoid adding freeware software you simply won’t utilize. Avoid downloading and installing browser extensions and applications you aren’t familiar with. • Always download applications from the original site. The majority of PUPs find their way to your computer is through download portals, so stay away from it entirely.
