Restore default Display Color settings in Windows 10

The color settings in a Windows computer certainly matter a lot especially when it comes to printing pictures. Users who are found or edit photos for a living change their computer’s color settings in order to ensure that the printout looks like the actual colors. However, those settings might not be appropriate for computer display and you can really tell right away that there something’s not right in the display. You might also notice some weird tint which isn’t easy to get rid of. You can’t actually tell the difference at first, not until you look at some other computers and then wonder what’s wrong with yours so, in this guide, you will know how to restore the display color settings back to their default state on your Windows 10 PC.

Make sure to follow each one of the steps laid out below carefully to restore the default Display Color settings.

Step 1: Set the Color Management Settings to default.

  • In the Start search box, type in “color management”. Once you see it in the search results, open it.
  • Once you’ve pulled up the Color Management window, go to the Advanced tab. From there, make sure that every single option is set to default – from all the options in both the “Windows Color System” and “ICC rendering intent to WCS gamut mapping”.

Note: You also have the option to reset it for everyone by simply clicking on the “Change system defaults” button.

  • Finally, you can also try to calibrate your display.

Step 2: Set the Graphics Properties to default.

After making changes in the Color Management settings, you need to also set the Graphics Properties to default.

  • Start by right-clicking on any empty space on your desktop.
  • Then select the Graphics properties from the context menu. From the Graphics properties window, you will see that most sections have to restore defaults.

Step 3: Try using Nvidia Color Settings for Desktop

The next thing you can try is using the Nvidia Color Settings if you have Nvidia graphics installed on your Windows 10 PC. Just the Control Panel to reset the color settings.

  • From the system tray, launch the Nvidia control panel.
  • Next, go to Display > adjust desktop color settings.
  • From there, select the display and then select the Nvidia Settings.
  • After that, change the options accordingly in order to get the correct combination though you can always leave them to default.

Fix Google Chrome error “He’s dead, Jim!”
If you always use the Google Chrome browser in browsing the internet, then you might have come across an error message saying, “He’s dead, Jim!” along with a funny looking face that’s peeking its tongue out and another detailed message saying, “Either Chrome Ran out of memory or process for the webpage has terminated for some other reason. To continue, reload the webpage or go to another page”. This error message in Google Chrome is actually quite famous and it appears for various reasons but it may have something to do with a memory issue. The Google Chrome browser is known to consume a lot of memory and the more web pages you open and load, it takes up more resources. Thus, the first thing you need to do when you encounter this error is to simply click the Reload button to continue browsing the internet or close the browser and then open it again. On the other hand, if you keep seeing this error message, then that’s a whole different story as you have to take some action to prevent it from popping up again, for good. Follow the instructions given below to fix the error in Chrome.

Option 1 – Reduce Google Chrome’s memory usage

The first thing you can try is reducing the memory usage of the Chrome browser. However, this option has a bit of a disadvantage. If a website crashes, all the instances of that website will also crash although other open tabs and websites won’t be affected. This process is referred to as “Process-per-site” mode which you will have to launch Chrome within this parameter.

Option 2 – Run Google Chrome with Strict Site Isolation

Aside from reducing Chrome’s memory usage, you can also run the browser with the Strict Site Isolation which makes sure that the crashing of one tab in the browser won’t affect the entire Windows as this feature will run every website you open on its own isolated process.

Option 3 – Run the built-in Malware Scanner and Cleanup tool in Chrome

In case you don’t know, there is actually a built-in malware scanner and cleanup tool in Chrome that helps you get rid of any unwanted ads, pop-ups, and even malware, as well as unusual startup pages, toolbars, and other things that could affect the performance of the browser.

Option 4 – Reset Google Chrome

Resetting Chrome can also help you get rid of the “He’s dead, Jim!” error message for good. Resetting Chrome means restoring its default settings, disabling all the extensions, add-ons, and themes. Aside from that, the content settings will be reset as well and the cookies, cache, and site data will also be deleted. To reset Chrome, here’s what you have to do:
  • Open Google Chrome, then tap the Alt + F keys.
  • After that, click on Settings.
  • Next, scroll down until you see the Advanced option, once you see it, click on it.
  • After clicking the Advanced option, go to the “Restore and clean up the option and click on the “Restore settings to their original defaults” option to reset Google Chrome.
  • Now restart Google Chrome.

Option 5 – Perform a clean reinstall on the Chrome browser

Although reinstalling any program is easy, not so much for Google Chrome as you need to make sure that the User Data folder is deleted before you reinstall it.
  • Tap the Win + R keys to open the Run prompt.
  • Then type %LOCALAPPDATA%GoogleChromeUser Data in the field and hit Enter.
  • Next, rename the “Default” folder inside the path you were redirected to. For instance, you can rename it to “Default-old”.
  • After that, install the Chrome browser again.

Option 6 – Try to flush the DNS and reset the TCP/IP

There are instances when a network goes into haywire because of a bad DNS. Thus, a bad DNS might be the one that’s causing this headache so it’s time for you to reset the entire network to resolve the issue. To reset the network, here’s what you have to do:
  • Click the Start button and type in “command prompt” in the field.
  • From the search results that appear, right-click on Command Prompt and select the “Run as administrator” option.
  • After opening Command Prompt, you have to type each one of the commands listed below. Just make sure that after you type each command, you hit Enter
    • ipconfig /release
    • ipconfig /all
    • ipconfig /flushdns
    • ipconfig /renew
    • netsh int ip set dns
    • netsh winsock reset
After you key in the commands listed above, the DNS cache will be flushed and the Winsock, as well as the TCP/IP, will reset.
  • Now restart your computer and open Google Chrome then try opening the website you were trying to open earlier.
Note: You can also try changing the DNS server to the Google Server, i.e. 8.8.8.8, and then see if it works for you or not.

Option 7 – Disable both the antivirus and firewall temporarily

As you know, both the firewall and antivirus programs are there to protect the operating system from any malicious threats. So if they find that there is some malicious content in a website you are visiting, they will block the site right away. Thus, it could also be the reason why you’re getting the “He’s dead, Jim!” error so you need to disable both the firewall and antivirus program temporarily and then try opening the website again. If you are able to open the website, you need to add this site as an exception and then enable the firewall and antivirus program back.

Setting default applications in Windows 11
Setting default applications in Windows 11Same as in previous Windows versions, Windows 11 will also use certain applications as default ones for opening certain file types and file extensions. And yes, same as in previous versions it will come preconfigured for certain file types and associated applications like for example photos for pictures. Of course, users usually have their own favorite applications for certain file types and much more prefer to open them inside the application of their choice instead of the default one. We can change the default application like in previous Windows versions but this time there are two ways and overall more control of this process. Windows 11 has settings for choosing default file type applications and default file extension applications giving you more control of this process.

The opening setting for apps

Whatever you wish to change default application or default extension application you will need to open settings for default application. Follow steps to quickly go into it.
  1. Press ⊞ WINDOWS + I to open settings
  2. Select Apps on left
  3. On the right part select Default Apps
Now you are in settings for choosing default applications

Choosing default application by file type extension

This is considering by Microsoft as a typical way to set default applications inside Windows 11. Once you are inside the settings app there is a box labeled Enter a file type or link type. Inside the search box, type in file extension that you wish to associate the application with like .JPG, .TXT, or other. If the file extension is not associated with any application you will be presented with a Choose a Default button, if however, the file extension is already associated with the app, you will need to click on the app box itself. In any case, a pop-up will appear and ask How do you want to open YOUR FILE EXTENSION files from now on? Choose Application from the list of presented ones and click on OK.

Choosing default file type

Another method is to select the default application by file type selecting application for it. In the settings screen, under the search box, you will have a list of installed applications. Choose the application that you would like to associate a file type with and click on it. On the next details screen scroll down and select the file type that you want to associate with the selected application and click on OK.

Other/third method

There is also the third method for choosing the default application for file type but it includes some surfing on your hard drive and it can be more time-consuming for first-time settings. But it is fairly quick when you need to only use it once on some new file type (for example you have a new application installed and want to switch just one file type extension to that application). Locate the file that you want to associate with the application and right-click on it. Select Open With from the menu and then Choose Another App. Pop up will appear, select the application that you would like to use, and check the box beside Always use this app to open CHOOSEN EXTENSION files followed by clicking on the OK button.

Nostalgia hit: Commodore 64 emulator and games
If you are a kid or in your teenage years you maybe will be not familiar with Commodore 64 but we are welcoming you anyway to go with us on this journey through time and find out about one of the most influential and beloved home computer of all time.

commodore 64History of Commodore

Firstly shown to the world in January of 1982, at the Consumer Electronics Show, C64 caught attention right away with its low price of only $595. Although it had some issues like limited functionality in some fields and a non-wide range of use by 1984 its price dropped below $200 and it cemented itself as an affordable home computer for the middle class. In as same year Apple has released their Apple II computer with far superior capabilities, commodore 64 remains a middle-class favorite due to its price. Also, the company has decided to distribute its homemade computer via some other means including not only just electronics stores specialized in that kind of equipment but in general shops and big department stores, through toy stores and book shops as well as through specialized dealers. This has given C64 a more competitive edge and mixed with the affordable price it soon became a staple of home computing. c64 storeWith sales booming and the early reliability issues with the hardware addressed, software for the C64 began to grow in size and ambition during 1984. This growth shifted to the primary focus of most US game developers. The two holdouts were Sierra, who largely skipped over the C64 in favor of Apple and PC compatible machines, and Broderbund, who was heavily invested in educational software and developed primarily around the Apple II. In the North American market, the disk format had become nearly universal while cassette and cartridge-based software all but disappeared. So most US-developed games by this point grew large enough to require multi-loading. At a mid-1984 conference of game developers and experts at Origins Game Fair, Dan Bunten, Sid Meier, and a representative of Avalon Hill said that they were developing games for the C64 first as the most promising market. By 1985, games were an estimated 60 to 70% of Commodore 64 software. Over 35% of SSI's 1986 sales were for the C64, ten points higher than for the Apple II. Everything was great for Commodore but the industry was moving forward and by the year 1988, PC compatible computers were stated to be the largest and fastest-growing home entertainment systems pushing C64 on to second place. Also, Nintendo’s gaming system has started to take hold in the world with amazing 7 million systems sold in 1988 only. By the year 1991, many developers exited the gaming market for Commodore 64 home computer system and its popularity started to fall due to lack of software and not so many hardware changes. commodore salesCommodore announced that the C64 would be finally discontinued in 1995. However, only one month later in April 1994, the company filed for bankruptcy. When Commodore went bankrupt, all production on their inventory, including the C64, was discontinued, thus ending the C64's 11 and a half year production.

Legendary titles

The history of Commodore 64 is interesting ones and I believe that it has done much for computers in general, yes it ran 11 years and that seems like a small-time, but remember that it was 11 years of C64 alone, there were other computers released by the company but none except arguably AMIGA 500 has not reached that much popularity as Commodore 64. That being said the system has left some of the great titles in its catalog that are great to be played even today and have been classic games on other platforms, even on PC itself. That being said I am giving you the top 100 games for Commodore 64:

Fix Error Code 0x80090016 for PIN and MS Store
If you encounter Error Code 0x80090016 while trying to create a PIN or when you are using Microsoft Store, then you’ve come to the right place as this post will guide you in how you can fix this problem. Recently some users reported that they were unable to sign in or set up the Windows 10 Login PIN. Note that the potential fixes for this issue are totally different in both scenarios. Here’s the error message you get when you encounter the PIN related error:
“Something went wrong, We weren’t able to set up your PIN. Sometimes it helps to try again or you can skip for now and do this later.”
On the other hand, here’s the error message you get for the Microsoft Store-related error:
“Try that again, Something happened on our end and we couldn’t sign you in.”
Here are some potential fixes you can try to fix the Error Code 0x80090016 in the Microsoft Store:

Option 1 – Try to sync the Date and Time

The first thing you can try is to sync the Date and Time of your computer as the wrong Date and Time settings are one of the most common causes of connection problems like the Error Code 0x80090016. This is because of the incompatibility between the SSL Certificate validation date and the System Clock. Thus, you have to sync your System Clock. Refer to the steps below to do so.
  • Start by tapping the Win + I keys to open the Windows Settings.
  • Next, go to Time & Language > Date & time.
  • From there, turn the toggle on for the “Set time automatically and Set time zone automatically” option on the right-side panel.
  • After that, click on Region & language located on the left side panel and make sure that the Country or region on the right-side panel is set to the country you live in.
  • Now close the Settings app and restart your computer and see if it fixes the problem or not.

Option 2 – Try to re-register the Microsoft Store app via PowerShell

  • Tap the Win + X key combination or right-click on the Start button and click on the Windows PowerShell (Admin) option.
  • If a User Account Control or UAC prompt appears, just click on Yes to proceed and open the Windows PowerShell window.
  • Next, type in or copy-paste the following command to re-register the Microsoft Store app and tap Enter:
powershell -ExecutionPolicy Unrestricted Add-AppxPackage -DisableDevelopmentMode -Register $Env:SystemRootWinStoreAppxManifest.xml
  • Wait for the process to be completed and then restart your computer.

Option 3 – Try to reset the Microsoft Store cache

Just like browsers, Microsoft Store also caches as you view apps and games so it is most likely that the cache is no longer valid and must be removed. To do so, follow the steps below.
  • Right-click on the start button and click on Command Prompt (administrator).
  • Next, type in the command, “exe” and tap Enter. Once you do, the command will clear the cache for the Windows Store app.
  • Now restart your PC and afterward, try opening Microsoft Store again and then see if Error Code 0x80090016 is resolved or not.

Option 4 – Try to run the Windows Store Troubleshooter

The Windows 10 Store Apps Troubleshooter will help you in fixing the Error Code 0x80090016. This is a great built-in tool from Microsoft that helps users fix any app installation issues. So this is worth a try to solve the problem. This built-in tool also helps you fix the Windows 10 Store if it isn’t working. To use the Windows Store Troubleshooter, follow the steps below.
  • Tap Win + I keys again to open the Windows Settings panel.
  • Go to Update & Security and then go to Troubleshoot.
  • On your right-hand side, scroll down to find the Windows Store Apps and then click on Run the troubleshooter option and see if it fixes the problem.
On the other hand, you can use the options below if you encounter Error Code 0x80090016 while setting up your PIN.

Option 5 – Try to manage the NGC Folder

  • You need to boot your computer into Safe Mode first.
  • Next, delete all the contents of the NGC folder and you can do that by taking ownership of the folder first. To do so, refer to these sub-steps:
    • First, locate the concerned folder 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.
  • After you take ownership of the folder, you can now delete all of its contents.
  • Once you’re done, restart your computer and see if the problem is fixed.

Option 6 – Try to use the Group Policy Editor

  • Tap the Win + R keys to open the Run dialog box
  • Then type “gpedit.msc” in the field and hit Enter or click OK to open the Group Policy Editor.
  • Next, navigate to this setting: Computer Configuration > Administrative Templates > System > Logon
  • After that, double click on “Turn on convenience PIN Sign-in” and set its radio button to Enable. This policy setting has the following description:
“This policy setting allows you to control whether a domain user can sign in using a convenience PIN. If you enable this policy setting, a domain user can set up and sign in with a convenience PIN. If you disable or don’t configure this policy setting, a domain user can’t set up and use a convenience PIN. Note: The user’s domain password will be cached in the system vault when using this feature. To configure Windows Hello for Business, use the Administrative Template policies under Windows Hello for Business.”
  • After you set the radio button to Enable, it will turn on the Logins using the PIN. Note that setting the radio button to Disabled or Not Configured will turn off the Logins using the PIN.
  • Now exit the Group Policy Editor and restart your PC so that the changes can take effect.

Windows requires a digitally signed driver
Device drivers are needed in order for the hardware and software to communicate in an operating system. Some of these drivers are digitally signed. These kinds of drivers are drivers that are signed by their issuing authority in a way that the end-user or any third party won’t be able to modify them. And there are times when you encounter an error that says, “Windows requires a digitally signed driver” when you try to install or update device drivers. Driver Signing is the process of associating a digital signature with a driver package. Digital signatures are used in Windows device installations to verify the identity of the vendor providing the driver packages as well as to verify the integrity of the driver packages. All the drivers you usually install on your PC from Windows Update, Original Equipment Manufacturers, or some other third-party driver download software and so on must be verified digitally by Microsoft through the digital signature. A digital signature is an electronic security mark that verifies the publisher for the driver and all the relevant information related to it. That’s why Windows won’t run a driver if it isn’t certified by Microsoft, be it a 32-bit or 64-bit system – this is called the Driver Signature Enforcement. The only Kernel-mode drivers that Windows 10 will load are the ones that are digitally signed by the Dev Portal. However, the changes only affect the new installations of the operating system with Secure Boot on while the non-upgraded fresh installations would require drivers that are signed by Microsoft. The “Windows requires a digitally signed driver” error indicates that the driver you are trying to update or install hasn’t been signed digitally by the issuing authority, preventing you from installing or updating it. To resolve this issue, you can try to update the drivers directly from the manufacturer’s site. You could also disable driver signing via Group Policy Editor.

Option 1 – Update the device drivers directly from the manufacturer’s site

The reason why you’re getting the “Windows requires a digitally signed driver” error in the first place is that you might have downloaded the drivers from external media. It could also be that the drivers didn’t update for some time now and the issuing authority changed its policies. Thus, you can try to update the drivers straight from the manufacturer’s website and install them. If this option didn’t work, then you’ll have to disable the driver signing or its recognition in Windows 10. Keep in mind that doing so is not advisable if you have to use the concerned driver.

Option 2 – Disable driver signing via Group Policy Editor

  • Tap the Win + R keys to open the Run utility and type “gpedit.msc” in the field and tap Enter to open the Group Policy Editor.
  • After that, navigate to this policy setting: User configuration > Administrative templates > System > Driver installation
  • Next, double click on the “Code signing for device drivers” entry located on the right pane to open its properties where you’ll see the following description:
“This setting determines how the system responds when a user tries to install device driver files that are not digitally signed. It establishes the least secure response permitted on the systems of users in the group. Users can use the System in Control Panel to select a more secure setting, but when this setting is enabled, the system does not implement any setting less secure than the one the setting established. When you enable this setting, use the drop-down box to specify the desired response. “Ignore” directs the system to proceed with the installation even if it includes unsigned files. “Warn” notifies the user that files are not digitally signed and lets the user decide whether to stop or to proceed with the installation and whether to permit unsigned files to be installed. “Warn” is the default. “Block” directs the system to refuse to install unsigned files. As a result, the installation stops, and none of the files in the driver package are installed. To change driver file security without specifying a setting, use System in Control Panel. Right-click My Computer, click Properties, click the Hardware tab, and then click the Driver Signing button.”
  • Now select the radio button for “Enabled” and select Ignore from the drop-down menu under “When Windows detects a driver file without a digital signature”.
  • Then click on the Apply and OK buttons to save the changes made. This will get rid of the “Windows requires a digitally signed driver” error but take note that this will also make your system less secure.

Microsoft Windows 11 limitations surfacing
windows 11As more and more people get into insider preview of upcoming Windows 11 we will see more and more different takes and opinions on it. Generally speaking, the first wave was quite positive when it was previewed but how time is passing more and more limitations and frustration comes to the surface. Some of the limitation that is inside it, which have been confirmed by Microsoft itself includes features missing that we had in Windows 10 like moving the application to the taskbar in order to pin it, moving the file in the taskbar to open it in default application and some big annoyances like Windows opening widgets always in Edge no matter what is your default browser. Not being able to move the taskbar from the bottom is also one of many illogical things. There is not really a point in these missing features since they were working fine in Windows 10 and many users liked them since they could customize Windows more to their liking, now with this new look at limitations it reminds me personally much of apple macOS and I will be honest, I am not a big fan of that kind of thinking. If I wanted that kind of OS I would have gotten myself a MAC, not custom build PC, but hey, Linux is always a free alternative, and how Microsoft itself is pushing limitations and in my opinion bad design choices along with awful system requirements that might just be a case for a lot of users. I am really not sure what is logic behind these moves and I am sure they have their reasons but this time it seems that their take on the new OS is not resonating well with the overall user population, well at least what I have heard so far. Things of course can still be changed and made for the better and I would rather see release postponed and issues addressed than getting more system hogging and limited new OS that at its current state looks like reskinned Windows 10 with limitations.

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. Wondering what makes the world’s most secure computers so safe?

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. Need to up your remote work security game before there’s another entry on the list of most deadly computer viruses?

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. Can your printer get a virus? See our cool infographic: The State of Printer Security

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. Where will cybersecurity go next? See our guide: The Future of Cybersecurity

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.
