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.

viruses10 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.

How to avoid errors in Windows

We have all experienced Windows errors over time and that can range from simple ones that will do very little to no harm and can be even system breaking making us lose our work or completely making the PC unusable. No one likes them but they happen, and usually, they happen once we least expect them.

No matter how frequent and unpleasant they might be there are ways to keep them at the minimum and even avoid them.

We will discuss steps that you can take in order to do this, simple tips and guides on how to keep your computer in top form and eliminate not just Windows, but any kind of errors altogether.

computer free of errors

Keep your hardware clean

Believe it or not, some serious Windows errors like the dreaded blue screen of death can come from hardware issues not from the software at all. It is very important to keep your computer clean and with enough air flow so it can function properly.

Not so far ago we had an article about cleaning your hardware detailing what and how to do it. Here is a link to the article: https://errortools.com/windows/cleaning-your-pc/

Do not keep applications you are not using

Keeping applications on the drive might seem harmless but sadly that is not the case. Some applications have a certain impact on the system itself after all most of them are tweaking registry entries in Windows and sometimes having too many applications means an increased possibility of conflict over certain resources even when they are not running.

Some applications like adobe creative suite, for example, will have certain services always running in the background, and more of these kinds of applications you have, more services, more places for unexpected errors when they collide. Some of them will also install certain dependencies that could be problematic.

The general idea is: if you are not using it, uninstall it and you will be safer and more resilient to errors inside OS.

Do not use pirated or cracked software

Besides moral and law implications that using pirated or cracked software might bring you there are also certain other things that might be problematic. Certain "free" software might come packet with some problematic malware, for example, it is not uncommon for attackers to use some popular software to pack their malicious application with it.

Other things might be wrong and incomplete tweaking with application in order to bypass security and thus bringing some instability due to scripts needed to run in order to achieve this goal.

Keep your drivers updated

Errors can also come from old drivers or bad drivers, device manufacturers are not all-knowing and perfect, and sometimes drivers can wreak havoc on the system. Having updated drivers can minimize any kind of unexpected behaviors inside the operating system making it more stable and reliable.

You can check your driver version in the control panel inside the Windows OS and then compare it to the ones found on the manufacturer's site, if there are newer available it is recommended to download and install them,

Keep software updated

Applications can have bugs, and bugs can lead to certain errors both in the system and when using the app as well. It is in your best interest to get the latest patch or newer version of the software in order to avoid these unpleasant experiences.

Also, certain codecs and extensions that are installed directly in Windows can also have some unpredictable behavior, updating is the best solution to keep them in line.

Keep Windows updated

Same as with drivers and applications, Windows itself is not immune from bugs and some unpredictable issues. Luckily Microsoft is always working on fixes and features of Windows but in order to actually have benefited from that work, you will need to keep Windows updated. Sometimes a bad update can introduce some errors but you can always roll back to the previous and wait for them to fix everything and then download them all.

Check the health of your hardware regularly

Hardware components have their life cycle, more quality ones tend to last longer but eventually, they will reach the end of their lifecycle. There are a lot of testers for various components in your computer that can check different things and provide you with information about the state of your components.

If you are on Windows 11, Microsoft has included a basic health app inside OS, just type PC health check in search and start the app. For some more detailed information and advanced checks, you will have to use a custom application. There are plenty of them specialized for single components like RAM, SSD, etc. A simple google search with providing you with top results and most of them are free for personal use.

Remember, a faulty component or component that is reaching its life cycle can produce many errors inside the operating system.

If you are checking for an update on your Windows 10 PC and you got the error 0x80070005 due to some ACCESS DENIED permissions issue, then read on as this post will show you what you can do to fix the problem. For some reason, the Windows Update does not have enough rights or permissions to continue further which is why you’re getting an error instead. Thus, the first thing you can do before you troubleshoot further is to make sure that you’re logged in as admin. However, if you’re already logged in as one, then here are some suggestions that might help you fix the Windows Update Install Error 0x80070005.

Option 1 – Restart your computer and try installing the Updates again

You can restart your computer and then try installing the updates once again. There are instances when a simple restart resolves Windows Update errors. Thus, after you restart your computer, check for updates once again and see if you’re still getting the error or not.

Option 2 – Delete the contents in the Software Distribution folder and Catroot2 folder

  • Open the WinX Menu.
  • From there, open Command Prompt as admin.
  • Then type in the following command – don’t forget to hit Enter right after typing each one of them.
net stop wuauserv net start cryptSvc net start bits net start msiserver
  • After entering these commands, it will stop the Windows Update Service, Background Intelligent Transfer Service (BITS), Cryptographic, and the MSI Installer
  • Next, go to the C:/Windows/SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.
After resetting the SoftwareDistribution folder, you need to reset the Catroot2 folder to restart the services you just stopped. To do that, follow these steps:
  • Type each one of the following commands.
net start wuauserv net start cryptSvc net start bits net start msiserver
  • After that, exit Command Prompt and restart your computer, and then try to run Windows Update once more.

Option 3 – Try running the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter is one of the things you can first check out as it is known to automatically resolve any Windows Update errors like error 0x80070005. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button. After that, follow the next on-screen instructions and you should be good to go.

Option 4 – Take control of the User App Data

There are times when permission to access the files is not configured correctly. As a result, it blocks the downloading of the updates. Thus, you have to take full control of the User App Data which is placed at C:/Users/USERNAME/AppData.
  • First, go to C:/Users/USERNAME/AppData and right-click on it then select Properties.
  • Next, click on the Edit button in the Properties window and click OK to confirm if you got a User Account Control elevation request.
  • After that, select user/group from the permission windows or click on the Add button to add another user or group. It would be best if you add “Everyone” to give permission.
  • Then check “Full Control” under the “Allow” column to assign full access rights control permissions.
  • Now edit the permission to Full Control for “Everyone”.
  • Click OK to save the changes made and then exit.

Option 5 – Try to update Windows after a couple of minutes or an hour

There are times when the issue is from Microsoft’s end. It could be that there’s some issue with Microsoft’s server so it would be better if you give it a couple of minutes or an hour or so before trying to run Windows Update again.

Arrows keys are not working in Microsoft Excel
As you know, Excel sheet is frequently acclaimed as one of the most useful software that allows users to create spreadsheets, crunch numbers as well as prepare a business report. Usually, tapping the arrow keys to move from one cell to another. However, there are times when you might experience trouble in tapping them – for instance, they won’t work when you tap them. This kind of problem can be quite frustrating since no matter what you do, especially when you tap the arrow keys, instead of a single cell, it moves the entire spreadsheet. If you are one of the users who experience this problem, worry no more for this post will guide you on what you can do to fix it. When arrow keys won’t function as intended in Excel spreadsheets, it could be due to unintended behavior of the Scroll key or it could be related to some issues with the keyboard driver. Whatever the cause is, here are some suggestions you can check out to fix it.

Option 1 – Try to disable the Scroll Lock

The first thing you can do to fix this problem with arrow keys is to disable the Scroll Lock. Although doing this is easy, newer laptops don’t actually come with it so if your keyboard does not come with a scroll key, all you have to do is tap the Fn key and disable Scroll Lock. Aside from that, you could also use the on-screen keyboard to turn off the Scroll Lock. You will see its status on the Excel sheet which will help you to double-check. Moreover, you could also tap the Shift + F14 keys to toggle off the Scroll Lock. To use the on-screen keyboard to turn off Scroll Lock, follow the steps below.
  • Tap the Windows key and type “on-screen keyboard” and then tap Enter.
  • Once the on-screen keyboard is opened, you should see that the Scroll Lock is on the “On” position since the ScrLk keys are in blue.
  • Like pointed out earlier, you can utilize the Scroll Lock indicator located in the status bar as well as disable or enable the scroll key by using this feature on Microsoft Excel.

Option 2 – Try turning on the Sticky key

If disabling the Scroll Lock did not fix the problem, you can try turning on the Sticky Key instead. A lot of users reported that this option fixed the problem for them. So you should try to turn on the Sticky key and to do that, follow the steps below.
  • First, type “control panel” in the Start Search and click on Control Panel from the search results.
  • Next, select the “Turn On Sticky Keys” option and click on OK.
  • After that, go back and uncheck the “Turn On Sticky Keys” option. This should fix the malfunctioning arrow keys on Excel.

Option 3 – Try running the Hardware and Devices Troubleshooter

The first thing you can do to fix the problem is by running the Hardware Troubleshooter. Although it won’t make much of a difference, there’s still a possibility that it could automatically fix the problem with these function keys. To use it, refer to these steps:
  • The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
  • After opening Settings, look for the Update and Security option and select it.
  • From there, go to the Troubleshoot option located on the left-hand side of the list.
  • Next, select Hardware and Devices from the list and open the Troubleshooter and run it. Once it is doing its job, wait for it to complete the process and then restart the system.
  • After the system restarts, check if the problem’s now fixed. If not, refer to the next option given below.

Option 4 – Update the keyboard driver

You can also update the keyboard driver to fix the problem. There are cases when an outdated or corrupted driver can fix the problem. To do so, follow the steps below.
  • Tap the Win + R keys to open the Run dialog box.
  • Then type “devmgmt.msc” in the field and hit Enter to open the Device Manager.
  • From there, look for the keyboard driver and click on it.
  • Next, right-click on the keyboard driver and select the Update driver option.
  • After that, click the “Search automatically for updated driver software” option to proceed.

Option 5 – Reinstall the keyboard driver

If updating the keyboard driver didn’t help, then you might want to reinstall it. How? Follow the steps below.
  • Tap the Win + R keys to launch Run.
  • Type in 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. Look for the keyboard driver, right-click on it and then select “Uninstall device”.
  • After that, unplug the device and restart your PC.
  • Then plug your device back in. Assuming your device is connected to your PC, open the Device Manager again.
  • Next, click on the Action button and click the Scan for hardware changes button. That should fix the problem
Note: You could also completely uninstall the driver and go directly to the manufacturer’s website and download the latest driver for your hardware and then install it.

Are gaming mousepads worth their price?

Mousepads are a common thing among computer users, everyone is using them and know what are they good for. Recently in the past few years, there are a lot of gaming mousepads on the rise, do you really need them, and do they back up their price? Short answer: YES, long answer: keep reading below.

gaming mousepad

Size advantage

One of the first things that one can see is the great difference in sizes between a regular mouse pad and a gaming one. Gaming pads have much more variety in size spawning all the way to really judge ones that you can use on your whole desk and place both keyboard and mouse on them. This will, of course, let you move your mouse more freely and have a much larger surface to use without the need to always lift the mouse up and center it on the regular pad.

Material advantage

Material on what are gaming pads built upon is extremely high in quality and usually even water phobic or water-resistant and it will allow great mouse movements on it. The backside is usually made of high-quality fabric that will stop slipping on the desk so the pad will stay at its pace during long sessions of work or gaming. Usually, standard mousepads are made with plastic or some other cheap material whereas gaming pads are made from fiber, high-quality fiber.

Other advantages

Among other great stuff that gaming pads have are wrist gel for hand resting and RBG light that looks cool, although RGB light is just a vanity that looks good gel for the wrist is a really good feature that will place less stress on your hands during long sessions of time spent in front of the computer.

Make AI images on your local PC

Stable Diffusion is a machine learning model developed by Stability AI to generate digital images from natural language descriptions. The model can be used for different tasks like generating image-to-image translations guided by text prompts and upscaling images.

Unlike competing models like DALL-E, Stable Diffusion is open source and does not artificially limit the images it produces. Stable diffusion was trained on a subset of the LAION-Aesthetics V2 data set. It can run on most consumer hardware equipped with a modest GPU and was hailed by PC World as "the next killer app for your PC".

stable diffusion

Since Stable Diffusion is run locally and not in the cloud, as mentioned there is no limit to the number of images that you can produce but in order to use it you will have to get down a little dirty with setting your PC environment for it since it is not really an application, it is a command line text based descriptor that will use python to generate your images, so there is no install nor GUI.

In this guide, we will show you how to both install and run Stable Diffusion on your local PC so you can start producing some cool images all by yourself.

Hardware and software requirements

Make no mistake, Stable Diffusion will not run on a potato PC, in order to harvest the power of AI-generated imagery this is what you will need:

  • A GPU with at least 4GB of VRAM
  • 10GB of hard disk space
  • Python and libraries (Miniconda3 installer will install everything you need)
  • The Stable Diffusion files
  • Git
  • Any OS (Windows, Linux, macOS)

Installing components

For this tutorial, we are covering the installation and running of Stable Diffusion on Windows PC. The steps presented here are presented in a way that installation can be performed on any operating system but precise instructions will be for Windows OS.

GIT

The first thing to do is to install GIT. It is a tool that will let you easily maintain and install repos from the internet. to install it go to: https://git-scm.com/ and click on download. Follow the instructions for your version of the operating system. If you are a developer you are familiar with GIT and if you already have it installed you can skip this step.

One thing that is important when installing GIT locally is to select to use it via the command line (the second option that says "Git from the command line and also from 3rd-party software").

Miniconda3

Now when we have GIT installed, next thing is to use Miniconda3 to install python and all required libraries that are needed. Get the installer at: https://docs.conda.io/en/latest/miniconda.html

Miniconda3 is basically an easy installer so you do not have to install tons of stuff manually from different websites and sources, it is nicely packaged in the installer that will take care of everything.

Stable Diffusion

After the previous two steps, we are ready now to actually install Stable Diffusion. Go to https://huggingface.co/CompVis/stable-diffusion#model-access and install the latest library (as of the writing of this article currently it is stable-diffusion-v1-4-original, the last one on the right), the library is almost 5GB in size so be prepared for big download.

After installing stable diffusion's latest library it is time to update it to the newest version. You can download ZIP from GIT HUB https://github.com/CompVis/stable-diffusion

Once downloaded click on the Windows start button and type in Miniconda3 and click on open. Create a folder and name it how you want on a drive of your choice. For this example, we will install it all in disk C under folder AI_art, follow the instructions below but use your own names and destination instead. Do not close Minicoda3 after typing commands!!!

cd c:/
mkdir AI_art
cd AI_art 

Extract GitHub files that you have downloaded into your new folder and get back to Minicoda3 and type the next commands:

cd C:\AI_art\stable-diffusion-main
conda env create -f environment.yaml
conda activate ldm
mkdir models\ldm\stable-diffusion-v1

Let the whole process finish, some files are large and it might take a while. After the whole process is finished and completed, copy the checkpoint file that you have downloaded into: C:\AI_art\stable-diffusion-main\models\ldm\stable-diffusion-v1

After the file is copied rename it to model.ckpt and you are finished.

Running Stable Diffusion

The created environment is needed in order to actually use Stable Diffusion to create images. Each time you want to use it you will have to run it, so go into Miniconda3, and inside it type:

conda activate ldm
cd C:\AI_art\stable-diffusion-main

after we are inside the folder call the script with the parameters:

python scripts/txt2img.py --prompt "TXT DESCRIPTION OF IMAGE THAT YOU WANT TO CREATE" --plms --n_iter 5 --n_samples 1

and that's it, your image is created and it is located in C:\AI_art\stable-diffusion-main\outputs\txt2img-samples\samples

Choosing right LINUX distribution
LINUX has become more than just a dedicated server Operating system, more and more it is gaining ground in home computers as well and as services like Steam and Gog are offering their titles for LINUX it is gaining more and more ground daily.

Why LINUX?

So, what makes LINUX so good? First of all security, no other Operating system has that high level of security like LINUX and that is the reason why it is widely used as a server. Other advantages are it is less resource hungry and its architecture is made in such a way that it does not has applications remains and traces which remain in the system, once an application is deleted from OS, it is deleted and every trace is removed from OS. Apple OS is based on LINUX kernel but made specifically for their hardware.

LINUX popularity

So naturally, the question pops up why LINUX is not more popular? One of the reasons is its difficulty, to work in LINUX you need to have some level of computer knowledge, Windows is more user-friendly and a lot of people prefer the ease of use to features. This is somewhat been fixed sort of speak in last years since we have LINUX distributions which aim to be more simple and user friendly but it is far from easy of use of one Windows. Another big reason was software support. Altho some powerhouse software has its LINUX versions and works just fine, even better than on Windows, your typical user applications lack and games were almost non-existent making LINU users rely on Windows emulation software for simple applications, and often it did not work properly. This has also changed for the better in later years but as with the previous point, it is still far from being Windows wide.

What is LINUX distro?

Linux comes in different versions called distributions. What this means is that the basic core of the Operating system is the same though all LINUX versions and all LINUX drivers and software will work on anyone, they will visually and feature-wise be different. Also, they will be more complex for use or they will have different hardware requirements. Choosing the right LINUX distribution is no easy task and we are here to help you by offering you certain points and guides in hopes to direct you on the right path.

What Do You Need the Distro for?

This might be perhaps the most crucial question when trying to decide which LINUX distribution you want to install. Depending on your preferences and goal like work, games, security, media you will need to consider the best distributions in the field of your preference. A very good place to get this kind of information is on DistroWatch. When on-site, navigate to the Distribution category search filter and choose the option best suited to your needs.

What Kind of Software Will You Be Using?

Like the previous question, this one is also your personal preference but it will make difference if you are planning to use a different type of software. If your plans are gaming for example you will want the latest and greatest LINUX kernel version for maximum hardware compatibility. If you are a regular desktop user you will aim for a distro that is updated constantly so you are working with the latest versions of Chrome or Firefox. In some cases, depending on your software you might want to run older but faster distribution.

What Kind of Hardware Will You Be Using?

If your computer is up to date you can run any distribution that you like but if it is an older rig your options might be a little limited. Now depending on the technical characteristics of your computer and its age it may come down to just a few available distributions which are specially tailored to run on old hardware. These kinds of distributions are lightweight and do not take much space but sadly can not offer you the latest and greatest in software but for usual everyday tasks like web browsing, word processing, email viewing, etc they work perfectly fine. You can have a great office machine with proper lightweight distribution offering you all that you need to be able to work.

How Much do you know about computers?

As stated before, LINUX is not as user-friendly as WIndows and your overall technical knowledge can play a big role in deciding which LINUX you want to adapt. If you are more of a casual user then avoid technical distributions which will require to manually tweak tons of stuff, go for more automated ones. If you are a power user however and enjoy wrestling with each detail then perhaps some distro with more command-oriented nature.

What Kind of Community Are You Looking For?

Now you might ask what does community has to do with the operating systems but the same as Windows, LINUX also can have some issues, and sometimes installing drivers will require certain steps to be taken. How it is much easier to find a solution when having a great community surrounding the project I suggest not dismissing this part when choosing your distro. Every community is helpful, but they’re all helpful in different ways. If you would like to read more helpful articles and tips about various software and hardware visit errortools.com daily.

Valve Steam Deck is Compatible with Windows 11
Steam DeckValve has officially announced that Steam Deck will be compatible with Windows 11 despite TPM 2.0 Microsoft requirements. From the beginning, Deck was announced like a mini handheld PC device. Powered with new Steam OS 3.0 based on Linux. However, besides out-of-the-box OS it was also stated that Deck will be a personal device meaning that other PC-based operating systems could be installed on it and even run your typical applications in it. Since Microsoft announced Windows 11 hardware requirements, specifically the TPM 2.0 requirement many users voiced concern that Steam Deck will not be able to connect to Windows 11 TPM 2.0 is something that Microsoft requires for every internal and hardware component that is to connect on a Windows 11 device. This is to ensure that only trusted devices would be included in the array of a PC setup and avoid any problems like malicious hardware injecting software into a system. This would also minimize the compromise Windows would have, as unverified or untrusted devices connect to a Windows PC. However, Valve and AMD are ensuring us that Deck will not have any issue connecting to a PC running Windows 11 or even if you wish to transform Deck itself into a Device running Windows 11.

This kind of error in Chrome can occur due to incorrect website domain configuration, conflicting browser data, incorrect proxy settings, and DNS connection issues. To resolve the ERR_TUNNEL_CONNECTION_FAILED error in Chrome, here are some suggestions you can check out.

Option 1 – Try disabling the proxy server for your LAN

If your PC was just attacked by some adware or malware as of late, it is possible that it has changed the network settings in the system and might display spam advertisements. Thus, you have to disable the proxy server for your LAN. To do that, refer to these steps:
  • Tap the Win + R keys to open the Run dialog box.
  • Then type “inetcpl.cpl” in the field and hit Enter to pull up the Internet Properties.
