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.

To make the Windows 10 operating system a lot more user-friendly, Microsoft introduced the Tablet Mode for Windows 10 devices, especially the 2-in-1 devices like Surface Pro and Surface Book. Despite the Tablet Mode’s efficiency, it also encounters some errors from time to time. One of the issues users reported about tablet mode is that they can’t turn off or exit tablet mode.

In an operating system, it is ideal for an administrator to have permission to access all the folders and files. However, there are times when you try to access the security settings or attempt to view the properties of a file, you could encounter an error saying, “You do not have permission to view this object’s security properties, even as an administrative user”. This kind of error may be caused by several reasons. For one, if your computer is infected with a virus or malware which might have caused some changes to the concerned folder or file. It could also occur if a program or service is using the folder or file simultaneously which explains why you’re not able to access the system. It could also be that the folder or file might have been owned by a user account that no longer exists or you might not have the permissions to view the targeted folder or file even though you’re logged in as administrator. To fix the “You do not have permission to view this object’s security properties, even as an administrative user” error, here are some options that might help.

Option 1 – Put your computer in a Clean Boot State

You can also troubleshoot the problem in a Clean Boot state. It could be that there are some third-party applications in your computer that’re preventing you from accessing security settings or properties of a file and to isolate this possibility, you need to boot your computer in a Clean Boot State and then try installing the program again. Putting your computer in this state can help you identify which program is the culprit and thus isolates the problem. In a Clean Boot state, your computer will start using only the pre-selected minimal set of drivers and startup programs. Note that you have to disable and enable one process at a time.

• Log onto your PC as an 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.)
• After you’ve set your computer into a Clean Boot State, try to check if the error is now fixed and that you can now view the Properties.

Option 2 – Try booting your computer into Safe Mode and delete inactive users

Aside from the Clean Boot State, you can also reboot your computer in Safe Mode and then delete all the inactive users. There are instances when the folder was created or owned by a user account that’s either deleted or inactive now and so you need to get rid of these inactive user accounts to resolve the error.

• First, boot your computer in Safe Mode.
• Then right-click on the concerned folder or file and select Properties.
• Next, select Advanced in the Security tab and click on Add.
• A new window will appear and from there, click on “Select a principal”.
• And then type the name of the user to who you wish to give permissions in the “Enter the object name to select” box.
• Now select Check Names and this would resolve the user name.
• After that, click OK to save the settings. This will close the window and take you back to the previous one.
• Next, from the drop-down menu, change the Type to Allow and select the Full Control checkbox.
• Click OK to save the changes made and then restart your computer in a normal mode.

Option 3 – Try to take ownership of the folder or file

Another thing you can do to fix the problem is to take ownership and force the system into giving permissions to the Administrator. How? Refer to these steps:

• Type “command prompt” in the Windows Search bar and then right-click on the relevant search result and select “Run as administrator”.
• After that, if a User Account Control or UAC prompt appears, just click on Yes to proceed.
• Next, type and enter this command: TAKEOWN /F <path>
• Note that the <path> is the location of the folder or file in File Explorer.
• Now type and enter this second command: ICACLS <path> /grant administrators:F
• Finally, once the command has been executed, restart your computer and then see if you can now access the folder or file.

Option 4 – Try scanning your computer using Windows Defender

As mentioned, the error when accessing the security settings or properties of a folder or file might be due to a virus or malware. It could be that it had made some modifications that prevents you from accessing security settings or properties. To eliminate it, you have to scan your computer using security programs like Windows Defender.

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

If you encounter a Blue Screen error that points out to the CMUDA.sys, read on as this post will guide you in fixing it. The CMUDA.sys file is a Windows operating system driver file that is related to the USB Device Audio capabilities of a computer. There are times when this file causes Blue Screen error due to some conflicts in RAM or some incompatible firmware or hard disk issues, corrupted drivers or malware infection, and so on. There are various Blue Screen errors that are related to the CMUDA.sys file such as:

• KMODE EXCEPTION NOT HANDLED
• PAGE FAULT IN A NONPAGED AREA
• IRQL NOT LESS OR EQUAL
• SYSTEM THREAD EXCEPTION NOT HANDLED (CMUSBDAC.sys)

In most cases, the CMUDA.sys file usually triggers the SYSTEM_THREAD_EXCEPTION_NOT_HANDLED Blue Screen error. Although this Blue Screen error may seem complicated, its workarounds are straightforward so you won’t have any problems in following them.

Option 1 – Try to 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.
• After opening the Device Manager, locate the device drivers that are marked with a small yellow exclamation mark icon and right-click on each one to open their Properties. On the other hand, you can also look for sub-entries under Sound, video, and game controllers like the C-Media USB Audio Class
• 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. You can download the as C-Media USB Audio Class driver from the cmedia.com website.

Option 2 – Try to recreate the CMUDA.sys file

The first thing you can try is to recreate the CMUDA.sys file. Every time your Windows 10 PC boots up, it looks for all the system drivers in place and if it is unable to find them, it tries to create them. Which is why if you remove your corrupt driver file, chances are, you might get a fixed file recreated just for you. How? Refer to the steps below.

• Boot your Windows 10 PC in Safe Mode.
• Then open File Explorer and navigate to this location: C:/Windows/System32/drivers
• From there, look for the file named sys and rename it to CMUDA.old.

Note: As you can see, the file’s extension has changed from .sys to .old.

• Now restart your computer and check if the CMUDA.sys Blue Screen error is now fixed.

Option 3 – Run the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors. It can be found on the Settings Troubleshooters page. To use it, refer to these steps:

If you got an error message saying, The INF file you selected does not support this method of installation while trying to install a driver using the “Install” option in the right-click context menu, read on as this post will guide you in fixing the problem. The INF file mentioned in the error message is a text file that’s divided into different types of formatted sections. Each one of the sections is designed for a particular purpose. For instance, one section is designed to copy files or to add entries to the registry. INF files are used to install drivers. However, if something is wrong, you might encounter this error while installing a driver on your Windows 10 computer. To resolve this problem, you can try to download the driver again from the official manufacturer website or check if the driver is compatible with your computer’s operating system architecture or you can also try installing the driver from the Device Manager. For more details, follow the given options below.

Option 1 – Try downloading the driver again from the official website of the manufacturer

Usually, you shouldn’t encounter this kind of issue no matter what installation method you used on your Windows 10 PC. However, there are times when the driver itself is corrupted for some reason which is why you are unable to complete the installation and receive an error message instead.

Option 2 – Try checking if the driver is compatible with the OS architecture

It is possible that you’re getting this error if you have a driver that is compatible with a 32-bit system and you are trying to install it on a 64-bit system and vice versa. Thus, you need to check if the driver you are trying to install is compatible with your operating system if you haven’t done it when you’ve downloaded the driver from the website of the manufacturer. To check the system architecture, in the Start Search, type “msinfo32” in the field and hit Enter to open the System Information window. From there, you should see all the information about your operating system. In addition, you can also search “system information” in the Cortana search box and look for the System Type entry and open it.

Option 3 – Try installing the driver from the Device Manager

If you have the driver files on your PC and you have to update a driver, refer to the steps given below to be guided on how to install the driver from the Device Manager.

• From there, look for the driver you want to update, and then right-click on each one of them and select the Update Driver from the menu.
• After that, click on the “Browse my computer for driver software” option.
• Next, select the “Let me pick from a list of available drivers on my computer” option and then click the Next button.
• On the next screen, you should see the “Have Disk” option. Click on this option and then click on the Browse button to go to the location of the file. After that, you shouldn’t have any problem installing the INF file.

Option 4 – Try running the System File Checker Scan

The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the “The INF file you selected does not support this method of installation” error. SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
