RAC Manager not working, Error 0xc0000005

The Windows 10 Telemetry and Data Collection features are auto-enabled and they collect all sorts of user activity and sends it to Microsoft. Microsoft says that the data collected only enhances the overall user experience and Windows functionality better but the number of data breaches happening across the globe has forced users to be extra cautious about their data privacy. So naturally, from stronger passwords and other services management, it is only logical to turn off Windows data gathering. To do so:

• Press ⊞ WINDOWS + R to open the run dialog.
• In the Run dialog type: taskschd.msc
• Press CTRL + SHIFT + ENTER key combo to open Task Scheduler in admin mode.
• On the left pane, navigate to the: Task Scheduler Library > Microsoft > Windows > Customer Experience Improvement Program
• At the location, on the middle pane, right-click on the task named Consolidator and select Disable from the context menu...
• Repeat the process with all other tasks listed in the middle pane.
• Exit Task Scheduler.

Solution

Error Causes

More and more Windows users are having trouble upgrading their operating system to Windows 10. There are a lot of errors being encountered by users and one of them is the Error Code 0xc1900106. This error is normally due to the misconfigured system files. If a Windows user encounters this error, most likely their device has some registry problems.

Further Information and Manual Repair

Fixing error code-related issues could be best resolved to do manual repair methods. Applying repair methods manually can help Windows users address the root causes of the errors they encounter, as well as apply definite solutions to rectify the issue.

Most Windows users can be able to implement manual repair methods themselves but there are some cases where help from a Windows professional is needed. If you’re not a very tech-savvy person and not confident performing the manual repair methods yourself, it would be advisable to seek help from a professional Windows technician who is knowledgeable enough to address the errors or problems you are encountering. However, if you don’t want to resort to seeking help from a professional, you can also consider using a powerful automated tool.

In trying to fix Error Code 0xc1900106, here are the following manual repair methods you can take:

Method One: Custom Installation

1. Make a backup of your personal files
2. Users of Windows 8/8.1 should Refresh first then proceed to upgrade.
3. If the Refresh process does not work, reset your device then try again.
4. If resetting your device still does not work, you can proceed with a custom installation.
5. When your Windows installation media is ready, you need to choose to boot from CD, DVD, or USB drive to begin setup. (For example purposes, this article will discuss booting from DVD).
6. When your device is all set to boot from DVD, you will be prompted to Press any key to boot from CD or DVD…
7. Once you’ve pressed any key, the screen will show the Windows logo which might take a while. No need to worry though, as long as you can see the indicator, you’re good.
8. Choose your Language, Time, and Keyboard method from the drop-down menu then hit Next.
9. Click on the Install Now button then wait until Setup begins.
10. Tick on the I accept the license terms check box then select Next.
11. Choose Custom: Install Windows only (advanced)
12. Choose the Primary partition then select Next. You will be prompted by the following warning: The partition you selected might contain files from a previous Windows Installation. If it does, these files and folders will be moved to a folder named Windows.old. You will be able to access the information in Windows.old, but you will be able to use your previous version of Windows. Just click the OK button then wait as the Windows continue to install. Windows will restart once this phase of the setup completes and will reboot into setup once again.
13. At this point, Windows will detect and install your hardware. Once this finishes, Windows will restart again.

Method Two: Reset Windows Update Components

1. From your device’s desktop, hit Windows key + X to open the command prompt as admin.
2. Once the command prompt window appears, you can type or copy and paste the following commands (all at once):

net stop wuauserv net stop cryptSvc net stop bits net stop msiserver ren C:WindowsSoftwareDistribution SoftwareDistribution.old ren C:WindowsSystem32catroot2 catroot2.old net start wuauserv net start cryptSvc net start bits net start msiserver pause

3. Exit the command prompt.
4. After you reset the Windows Update components, see if you receive Windows Updates which includes the firmware updates for your computer.

Method Three: Ensure Windows is Updated

1. If you have an antivirus, make sure to disable it during the upgrade process.
2. Run Windows Update to check if the system is updated.
3. Ensure that the latest firmware and drivers are installed. To be able to do this, go to the computer manufacturer’s website or you can also try contacting company support.

In case you don’t know, the Title bar comes with the Maximize, Minimize, as well as the Close button. However, there are instances when you might notice that the Title bar, Maximize, Minimize and Close buttons are missing in the File Explorer. This kind of problem might be due to some glitch in the computer, or it could also be caused by some built-in tool or an installed program in your computer. Moreover, there are also other factors that you have to consider such as corruption in the system files as well as errors in the user profile which is generated on a domain network, and so on. There are several suggestions you can check out to fix the problem. You can try to boot your computer in a Clean Boot State to see if a third-party program is the root cause of the problem. You can also try to run built-in tools like System File Checker and the DISM tool. You could also get the video buffer emptied, reset or reinstall the program, or recreate the User Profile.

Option 1 – Put your computer in a Clean Boot State

As pointed out, it is possible that some third-party program or service is the one that’s behind the problem. To isolate this possibility and to identify the culprit, you have to put your computer into a Clean Boot State. To do so, follow the steps below.

• Log onto your PC as administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• You need to disable one third-party app after the other to really isolate the issue. And once you’ve narrowed down the problem, you can either disable the third-party app that’s causing the problem or remove it.

Option 2 – Run System File Checker scan

You might also try running the System File Checker or SFC scan to fix the issue. System File Checker is a command utility built into your computer that helps restore corrupted files and missing files. Refer to the following steps to run it:

• Hit the Win + R keys to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

• Restart your computer and see if the System32 folder still pops up at startup or not.

Option 3 – Try running the DISM tool

You can try running the Deployment Imaging and Servicing Management or DISM tool to fix the Windows Upgrade problem. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.

• Open the Command Prompt with admin privileges.
• Then type in the following commands and make sure to hit Enter right after you type each one of them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • exe /Online /Cleanup-image /Restorehealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 4 – Try to empty the Vide buffer

These kinds of problems could also be due to bad data in the Video Buffer. Thus, you can try to empty the Video buffer to resolve the problem. All you have to do is tap the Shift + Ctrl + Win key + B keys on your keyboard. After that, leave your computer idle for about 10 seconds until you notice it blink once. Now you try using your computer as usual and see if the glitch is now fixed or not.

Option 5 – Try to reset or reinstall the program

Another thing you can do to fix the issue is to reset or reinstall the program where you encounter the problem. Chances are, you are running the application in the Full-screen mode but you can exit it by simply tapping the Esc or F11 key. However, if nothing changed, then consider resetting or reinstalling the program. Just go to the Windows 10 Settings app and navigate to Apps > Apps & Features. From there, look for the entry of the application you’re having problems with and select it and then click on the Advanced options. After that, click on the Reset button under the Reset section.

Option 6 – Try recreating the User Profile

You might also want to try recreating the User Profile on your computer since some errors in the creation of a User Profile can result in problems like this one. Thus, you have to try deleting the User Profile and then recreate it.

If you encounter the BAD_SYSTEM_CONFIG_INFO Blue Screen error in your Windows 10 PC, then read on as this post will guide you in fixing this issue. Usually, this kind of Blue Screen error is caused by some issues with the Boot Configuration Data file. The main issue inside of the Boot Configuration Data file is that either some boot order files or older files might be in conflict with the newer ones or the stable ones and thus triggering the BAD SYSTEM CONFIG INFO Blue Screen error. This kind of Stop error also indicates that there is an error in the Windows Registry which is why you need to update potential culprit drivers as well as edit some entries in the Registry if need be. But before you get started, make sure that you create a System Restore Point first. After creating a System Restore Point, try to boot your computer into Safe Mode and then restart your computer normally. However, if it doesn’t work, proceed to the given options below.

Option 1 – Run System Restore

Performing System Restore might help you in fixing the BAD SYSTEM CONFIG INFO Blue Screen error. You can do this option either by booting into Safe Mode or in System Restore. If you are already in the Advanced Startup Options, just directly select System Restore and proceed with the next steps. And if you have just booted your PC into Safe Mode, refer to the steps below.

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

Option 2 – Update or rollback your device drivers

If the first option didn’t work for you, then it’s time to either update or roll back the device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.

• Open the Devices Manager from the Win X Menu.
• Then locate the device drivers and right-click on them to open the Properties.
• After that, switch to the Driver tab and click on the Uninstall Device button.
• Follow the screen option to completely uninstall it.
• Finally, restart your computer. It will just reinstall the device drivers automatically.

Note: You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer.

Option 3 – Try fixing the Windows Registry files

In order to fix the Windows Registry files, you need to make a bootable Windows 10 USB drive and then boot your PC using it. To do so, refer to the steps below.

• Once you see the Welcome Screen, click on Next.
• Then click on the “Repair your computer” option located on the bottom-left section of the window.
• Next, click on Troubleshoot > Advanced Options > Command Prompt.
• After opening Command Prompt, execute each one of the commands listed below in the sequence that they are given:
  • CD C:WindowsSystem32config
  • ren C:WindowsSystem32configDEFAULT DEFAULT.old
  • ren C:WindowsSystem32configSAM SAM.old
  • ren C:WindowsSystem32configSECURITY SECURITY.old
  • ren C:WindowsSystem32configSOFTWARE SOFTWARE.old
  • ren C:WindowsSystem32configSYSTEM SYSTEM.old
• After executing the commands given above, type in the next ones below and make sure to execute them in the given sequence below.
  • copy C:WindowsSystem32configRegBackDEFAULT C:WindowsSystem32config
  • copy C:WindowsSystem32configRegBackSAM C:WindowsSystem32config
  • copy C:WindowsSystem32configRegBackSECURITY C:WindowsSystem32config
  • copy C:WindowsSystem32configRegBackSYSTEM C:WindowsSystem32config
  • copy C:WindowsSystem32configRegBackSOFTWARE C:WindowsSystem32config
• Now type “exit” to close Command Prompt.
• Restart your PC for the changes to take effect.

Option 4 – Run a Memory Check to test RAM

On the other hand, you can also fix the BAD SYSTEM CONFIG INFO Blue Screen error by running a Memory Check using the Windows Memory Diagnostic. Refer to these steps to do so.

• Tap the Win + R keys to open the Run dialog box.
• Then type “mdsched.exe” in the field and hit Enter to open the Windows Memory Diagnostic.
• After that, the Windows Memory Diagnostic will give out two options such as:

1. Restart now and check for problems (recommended)
2. Check for problems the next time I start my computer

• Select any of the given options. After that, your computer will restart and check for memory-based issues upon the restart. If there are any issues, it will automatically them.

Option 5 – Rebuild BCD files and repair MBR files

Like what you did on the third option above, you also have to make a bootable Windows 10 USB drive for this option and then boot your Windows 10 PC using it.

• Once you get to the Welcome Screen part, click on Next.
• Afterward, click on the Repair your computer option located on the bottom-left part of the window.
• Then click on Troubleshoot.
• Next, select the Advanced Options and then Command Prompt.
• Once Command Prompt has been pulled up, enter each one of the following commands and in the sequence that they are given to rebuild BCD files and repair MBR files:
  • bootrec /repairbcd
  • bootrec /osscan
  • bootrec /repairmbr

• Now type “exit” to close Command Prompt and then restart your computer to successfully apply the changes made.

Code 0x800F0923 – What is it?

The Error Code 0x800F0923 is one that appears only when attempting to update from older versions of Microsoft Windows to Microsoft Windows 10. This error does not occur with every install and is believed to be the result of a driver incompatibility issue. It is unclear which specific drivers are having the compatibility issues, though it is widely believed that DuplexSecure's SPTD drivers are the ones at fault. When operating correctly, without errors, the update process should not take longer than 30 minutes. Common symptoms include:

• Error message window/pop-up during the install process, giving the Error Code 0x800F0923
• Inability to install and update from older versions of Microsoft Windows to version 10

• The Operating System (OS) upgrading does not support older hardware.
• Your computer’s specs did not meet the minimum requirements.
• Not enough hard disk space.
• The new software might lack software drivers for older hardware

Further Information and Manual Repair

Microsoft has recently released its Windows 10 operating system. While there are still a few kinks to be worked out, overall the reviews have been positive. As with any new Microsoft update, compatibility issues can arise. If you are unsure whether your current PC will be able to handle the new Windows 10, here is an easy way to check your system.

Method 1: Check if your computer is compatible

• Locate the “Get Windows 10” application icon in your notification tray (bottom right corner of your screen, white Windows logo).
• Right-click on this icon, then select the “check your upgrade status” option.
• Be prepared for the menu to take a few minutes to open.
• Click on the menu on the upper left-hand corner of this new dialog box. (It looks like three blue horizontal lines)
• Select “check your PC”
• After the system checks for compatibility, it will let you know whether or not your PC has the appropriate drivers, etc. (Keep in mind that this is not a foolproof method for checking compatibility status).

Method 2: Download or upgrade your drivers/software

If you have already attempted to update to Windows 10, and have received the Error Code 0x800F0923, this is the simplest way to solve the issue yourself.

1. Open the “Get Windows 10” application. 2. Open the menu in the upper left corner, looks like three blue lines. 3. Select “Check your PC”. 4.

If your computer does not have sufficient space to accept the upgrade, you might want to clear up some space on your computer. Here’s how to do it. If you have not attempted to install Microsoft Windows 10 yet, it is a good idea to check your system's compatibility prior to installing. While it is not absolutely necessary, it will save time and frustration. Microsoft Support suggests contacting them directly if you are unable to solve your driver compatibility issues, or if the above do-it-yourself method is unsuccessful. To resolve this compatibility issue and get your upgrade going use a powerful and user-friendly tool to clean up the problem. Click here to download Restoro. Users should also be aware that those who choose to upgrade to Windows 10 have 30 days in which they may decide that they would rather use their old system. However, reverting back to the older system may not be a smooth process, and some data could be lost.

Microsoft has been bringing new lock-screen features with every iterative feature release of Windows 10 in order to improve user experience. However, Windows 10 users have different opinions regarding it. Some users are pleased with it while some users simply do not like it. So if you are one of the users who seem to not approve of this feature, read on as this post will be about enabling or disabling the Console Mode sign-in feature in Windows 10. Before you proceed, take note that you will not be able to use your mouse pointer in this Consol Mode login screen and you can only use your keyboard to navigate around various options.

Step 1: Tap the Win + R keys to open the Run dialog box. Step 2: Then type in “Regedit” in the field and tap Enter to open the Registry Editor. Step 3: Next, navigate to the following registry path:

ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionAuthenticationLogonUITestHooks

Step 4: From there, look for a DWORD named “ConsoleMode”. If you don’t see this DWORD, you can just create a new DWORD and name it as “ConsoleMode” and make sure that its base is set to Hexadecimal. Step 5: After that, double click on ConsoleMode and change its value to “0” to disable it and “1” to enable it. Step 6: Now restart your computer to apply the changes made. Like pointed out, you can only use your keyboard when you’re in the Console Mode login window or screen. You can just use the ESC button to go back to the menu while you can utilize the arrow keys so you can go through the options that are mostly vertically arranged and the Enter key to select an option. In the Console Mode, sign-in using the Passwords and PINs worked efficiently.

Outlook PST Errors

Problems occur when your PST file becomes corrupted or hits the size limit. Outlook will start to display error messages. These errors include like 0x80040119, 0x80040600, and 0x8004060c.

Error Causes

You might think Outlook problems are just a minor inconvenience. You can’t access your emails and contact information, but that doesn’t actually affect computer security, right? Wrong! Outlook problems can indicate serious corruption issues within your system.

In many cases, your PST file can even be targeted specifically by a virus.

Today, many viruses are specially designed to steal personal information and then sell that information on the online black market. Since so much personal data is stored within Outlook’s PST file, this is often the first place that viruses look.

If you don’t want some hacker in a foreign country to read your emails, steal your contact information, or do all sorts of other dangerous tasks, then we advise you to fix your PST problem as soon as possible.

Other causes include hitting the 2GB memory limit on older versions of Outlook, erroneous SMTP settings, etc,.

However, thanks to powerful software like Stellar Phoenix Outlook PST Repair, it has never been easier to fix Outlook and recover all of the data inside your PST file.

ScanPST.exe rarely fixes problems with the PST file. Since the application is only a few megabytes in size, its effectiveness is very limited. Although Microsoft designed ScanPST.exe to be an effective solution to any PST files, it fails miserably.

Better Alternatives to Microsoft's ScanPST.Exe

Ultimately, after downloading ScanPST.exe and running it, your Microsoft Outlook will still be unable to send or receive emails. And, to make matters worse, you might also be unable to access contact data or read your old emails.

Unlike other PST repair solutions, ScanPST.exe will not recover deleted emails or other lost Outlook data. In fact, using ScanPST.exe can sometimes cause your personal data to become even more difficult to recover.

If you do want to try out ScanPST.exe, then go ahead. While it probably won’t make your PST errors worse, it won’t even come close to fixing them. If you’re ready for a more serious solution to PST problems, then keep reading.

A copy of Windows gets into a grace period when it is installed on a computer which means that you can use your Windows computer without any constraints on its feature. However, if you suddenly encounter an error code 0xC004F009 then this means that the grace period has already expired. In such cases, you will see the following error message on your screen:

“Error Code 0xC004F009, The Software Licensing Service reported that the grace period expired.”

One of the possible causes of this error is that it could be that the grace period has already expired way before the system was activated which is a result of which the system is in the Notifications state at this moment. The error code 0xC004F009 has something to do with MAK-enabled computers in an enterprise when it comes to Volume Licensing. One of the reasons that this error pops up is due to the possibility that the computer was not activated yet even when it was already connected to the Enterprise. Another most likely cause of the error is when the system was never connected with the Enterprise at all and the given grace period has expired before your computer system is activated. Whatever the real cause of this error, this post will guide you in fixing it. Just refer to the instructions given below to fix it.

Option 1 – Try activating Windows using the command-line tool

• First, you need to obtain your MAK key from the IT administrator.
• Once you have it, tap the Win + R keys on your keyboard and then type “cmd” in the field and hit Enter to open an elevated Command Prompt.
• After that, type this command and hit Enter to install the product key or replace the existing one: Slmgr.vbs –ipk <your mak key>
• Next, type another command and hit Enter: slmgr.vbs –ato
• Once you’ve executed the given commands, Windows should be activated after it connects to Microsoft servers and then gives it some time and try to check if error code 0xC004F009 is now fixed or not.

Option 2 – Try activating Windows using your mobile phone

Activating Windows 10 can also be done using your phone. Just note that you have to call Microsoft to do so.

• In the Start Search box, type in “Slui 4” and tap Enter.
• Next, select your country and click on Next.
• Keep the window open and call the toll-free number of the country you’re from.
• Afterward, a confirmation ID should be given by the automated system which you must take a note of.
• Finally, in the box on the window, type in the confirmation ID and click on the Activate button. That should do it.

Option 3 – Try to prolong the grace period

On the other hand, it is also possible for you to prolong the grace period but you might have to get another genuine Windows key for that. Before you proceed, you need to create a System Restore point first afterwards, refer to the steps given below to increase the grace period of the Software Licensing Service on your Windows 10 computer.

• Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field then hit Enter to open the Registry Editor.
• After that, navigate to this registry key: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionSetupOOBEmediabootinstall
• Next, change the value of the “mediabootinstall” key to “0”.
• Now open Command Prompt with admin privileges and then type this command and hit Enter: slmgr –rearm
• The command you just entered will add another grace period to your system activation. After that, you have to obtain a new key and then activate Windows.

Option 4 – Try running the Windows 10 Activation Troubleshooter

You can also try to run the Windows 10 Activation troubleshooter to help resolve the error code 0xC004F009.

• Go to Settings and then select Activation.
• After that, click on the Windows Activation and then troubleshoot. This will help you address most of the commonly found activation issues in Windows devices.

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. 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.
