10 Worst Computer Viruses in history

Computers viruses, worms, ransomware, etc. are kinds of malicious software that no user should take lightly. On several occasions, we have touched upon security steps that each user should take in order to protect its identity and data. Sadly sometimes even when all precautions are taken some malware can still slip through and wreak havoc. Today we are looking at some of the worst or the best, depending on your view that has indeed wreaked plenty of havoc.

viruses10 worst computer viruses in history

In the list of the 10 most famous computer viruses below, we show the costs, dates, reach, and other key facts. First a note about terms: we use the words “virus” and “worm” interchangeably because most readers search for them that way. But there’s a subtle difference that we explain after the list.

1. Mydoom – $38 billion

The worst computer virus outbreak in history, Mydoom caused estimated damage of $38 billion in 2004, but its inflation-adjusted cost is actually $52.2 billion. Also known as Novarg, this malware is technically a “worm,” spread by mass emailing. At one point, the Mydoom virus was responsible for 25% of all emails sent.
Mydoom scraped addresses from infected machines, then sent copies of itself to those addresses. It also roped those infected machines into a web of computers called a botnet that performed distributed denial of service (DDoS) attacks. These attacks were intended to shut down a target website or server.

Mydoom is still around today, generating 1% of all phishing emails. That’s no small feat considering the 3.4 billion phishing emails sent each day. By that figure, Mydoom has taken on a life of its own, infecting enough poorly-protected machines to send 1.2 billion copies of itself per year, 16 years after its creation.
Though a $250,000 reward was offered, the developer of this dangerous computer worm was never caught.

2. Sobig – $30 billion

The 2003 Sobig computer virus is actually another worm. It is second only to the Mydoom virus in its scope. The $30 billion figure is a worldwide total, including Canada, the U.K., the U.S., mainland Europe, and Asia. Several versions of the worm were released in quick succession, named Sobig.A through Sobig.F, with Sobig.F being the most damaging.
This cybercriminal program masqueraded as legitimate computer software attached to emails. It disrupted ticketing at Air Canada and interfered with countless other businesses. Despite its widespread damage, the creator of the successful bug was never caught.

3. Klez – $19.8 billion

Klez is a close third on the list of the worst computer viruses ever created. With nearly $20 billion in estimated damages, it infected about 7.2% of all computers in 2001, or 7 million PCs. The Klez worm sent fake emails, spoofed recognized senders and, among other things, attempted to deactivate other viruses.
As with other viruses and worms, Klez was released in several variants. It infected files, copied itself, and spread throughout each victim’s network. It hung around for years, with each version more destructive than the last.
Windows has come a long way since most of the computer viruses on this list hit the web. Thankfully, built-in protection with Microsoft Defender is always on the watch.

4. ILOVEYOU – $15 billion

The year 2000’s ILOVEYOU virus worked by sending a bogus “love letter” that looked like a harmless text file. Like Mydoom, this attacker sent copies of itself to every email address in the infected machine’s contact list. Shortly after its May 4 release, it had spread to more than 10 million PCs.
The virus was created by a college student in the Philippines named Onel de Guzman. Lacking funds, he wrote the virus to steal passwords so he could log into online services he wanted to use for free. He reportedly had no idea how far his creation would spread. This virus is also known as Loveletter.

5. WannaCry – $4 billion

The 2017 WannaCry computer virus is ransomware, a virus that takes over your computer (or cloud files) and holds them hostage. The WannaCry ransomware ripped through computers in 150 countries, causing massive productivity losses as businesses, hospitals, and government organizations that didn’t pay were forced to rebuild systems from scratch.
The malware raged like wildfire through 200,000 computers worldwide. It stopped when a 22-year-old security researcher in the U.K. found a way to turn it off. Computers with out-of-date operating systems were hit especially hard. That’s why security experts always recommend updating your systems frequently.

Ransomware strikes again

In September 2020, one of the potentially largest computer virus attacks in medical history hit Universal Health Services. The U.S. hospital chain, which has more than 400 locations, was reportedly struck by damaging ransomware. The attack forced the cancellation of surgeries and made healthcare workers switch to paper records.

6. Zeus – $3 billion

The Zeus computer virus is an online theft tool that hit the web in 2007. A whitepaper by Unisys three years later estimated that it was behind 44% of all banking malware attacks. By then, it had breached 88% of all Fortune 500 companies, 2,500 organizations total, and 76,000 computers in 196 countries.
The Zeus botnet was a group of programs that worked together to take over machines for a remote “bot master.” It originated in Eastern Europe and was used to transfer money to secret bank accounts. More than 100 members of the crime ring behind the virus, mostly in the U.S., were arrested in 2010. It’s not as prominent today, but some of the virus’ source code lives on in newer botnet viruses and worms.

Zeus caused documented damage of $100 million. But the real cost in terms of lost productivity, removal, and undocumented theft is undoubtedly much higher. A $3 billion estimate, adjusted for inflation, puts this virus at a cost of $3.7 billion in today’s dollars.

7. Code Red – $2.4 billion

First observed in 2001, the Code Red computer virus was yet another worm that penetrated 975,000 hosts. It displayed the words “Hacked by Chinese!” across infected web pages, and it ran entirely in each machine’s memory. In most cases it left no trace in hard drives or other storage.
Financial costs are pegged at $2.4 billion. The virus attacked websites of infected computers and delivered a distributed denial of service (DDoS) attack on the U.S. White House’s website, www.whitehouse.gov. In fact, the White House had to change its IP address to defend against Cod Red.

8. Slammer – $1.2 billion

The SQL Slammer worm cost an estimated $750 million across 200,000 computer users in 2003. This computer virus randomly selected IP addresses, exploiting vulnerabilities and sending itself on to other machines. It used these victim machines to launch a DDoS attack on several internet hosts, significantly slowing internet traffic.
The Slammer worm hit banks in the U.S. and Canada especially hard, taking ATMs offline in many locations. Customers of Toronto’s Imperial Bank of Commerce found themselves unable to access funds. The attack reared its ugly head again in 2016, launching from IP addresses in Ukraine, China, and Mexico.

9. CryptoLocker – $665 million

Thankfully, ransomware attacks like the 2013 CryptoLocker virus have dipped since their 2017 peak. This malware attacked upwards of 250,000 machines by encrypting their files. It displayed a red ransom note informing users that “your important files encryption produced on this computer.” A payment window accompanied the note.
The virus’ creators used a worm called the Gameover Zeus botnet to make and send copies of the CryptoLocker virus. According to a report by security firm Sophos, the average ransomware attack costs a business $133,000. If we estimate that CryptoLocker hit 5,000 companies, that would put its total cost at $665 million.

10. Sasser – $500 million

The Sasser worm was written by a 17-year-old German computer science student named Sven Jaschan. He was arrested at the age of 18 in 2004 after a $250,000 bounty was posted for the computer virus’ creator. A friend of Jaschan’s tipped authorities that the youth had penned not only the Sasser worm but also the damaging Netsky.AC attack.
Jaschan was given a suspended sentence after it was found he was a minor when he wrote the malware. The Sasser worm crashed millions of PCs, and though some reports put damages at $18 billion, the relatively low infection rate suggests a more likely cost of $500 million.
Other notable viruses

The top 10 worst computer viruses above are just the ugly tip of a gargantuan digital iceberg. With a million new malware programs popping up every 3 years, we may miss the forest for a few outstanding trees. Here are just a few more viruses that have wreaked havoc over the years:

Mimail: This worm tried to harvest data from infected machines to launch a string of DDoS attacks, but was relatively easy to remove.

Yaha: Yet another worm with several variants, thought to be the result of a cyber-war between Pakistan and India.

Swen: Written in C++, the Swen computer worm disguised itself to look like a 2003 OS update. Its financial cost has been pegged at $10.4 billion, but not reliably.

Storm Worm: This worm showed up in 2007 and attacked millions of computers with an email about approaching bad weather.

Tanatos/Bugbear: A 2002 keylogger virus that targeted financial institutions and spread to 150 countries.

Sircam: A computer worm from 2001 that used counterfeit emails with the subject line, “I send you this file in order to have your advice.”

Explorezip: This worm used fake emails to spread to every machine on thousands of local networks.

Melissa: The most dangerous computer virus in 1999, Melissa sent copies of itself that looked like NSFW pics. The U.S. FBI estimated cleanup and repair costs at $80 million.

Flashback: A Mac-only virus, Flashback infected over 600,000 Macs in 2012 and even infected Apple’s home base in Cupertino, Calif. In 2020, there’s now more malware on Macs than on PCs.

Conficker: This 2009 virus still infects many legacy systems and could do significant damage if it ever activates.

Stuxnet: This worm is reported to have destroyed Iranian nuclear centrifuges by sending damaging instructions.

Quick Solution Guide to Error Code 40

Error Code 40 – What is it?

Error Code 40 is a device driver error that users encounter on any Windows 2000 and later operating systems. It occurs when the peripheral device that you connect to your PC cannot be accessed due to a change in the system registry.

This is due to the presence of invalid sub-keys of the device driver in the system registry. It is a common error that users come across and appears on your PC with either of the following messages:

“Information in the registry entry for this driver is invalid”

OR

"Windows cannot access this hardware because its service key information in the registry is missing or recorded incorrectly. (Code 40)"

Solution

driverfix boxError Causes

As mentioned above, the error code is triggered when the device driver’s invalid sub-keys appear in the registry, effectively changing it. This happens when the windows system files get damaged due to the following factors:

  • An incomplete program uninstallation
  • An incomplete program installation
  • Hardware is not removed properly
  • System recovery from viruses
  • An improper system shut down

Factors such as incomplete installations or uninstallations or an improper system shut down can cause files to become damaged that threaten the health of your computer.

Removing viruses from the computer is also another factor as it removes the entries in the Windows system files which contain the viruses including spyware or malware

Further Information and Manual Repair

Fixing Error Code 40 is similar to fixing other device manager error codes. Here are a few methods you can try.

Method 1 – Use System Restore

You can use system restore to eliminate the problem. Here is how you can use it:

  • Log in using an Administrator account
  • Click ‘Start’ button and select All Programs > Accessories > System Tools > System Restore
  • Click ‘Restore my computer to an earlier time’ and click ‘Next’
  • Select the last Windows restore point from the ‘On this list, click a restore point’ list, and click ‘Next’
  • Click ‘Next’ on the confirmation window to proceed
  • Restart your PC after restoration is complete
By restoring the system via a last saved system checkpoint, you can obtain undamaged Windows system registry files that can help avert the error code.

Method 2 – Manually uninstall then reinstall the device driver

If using system restore also does not work in removing the error code, you may have to resort to manually uninstalling and then reinstalling the device driver causing the problem.

This would be necessary since the remaining incomplete files due to a partial removal or installation of programs is what contributes to the error code. By uninstall and reinstalling the device driver program, it would lead to the completion of the files.

You can do this by firstly logging in as Administrator and open Device Manager. Select the device that is causing the problem and double click it and make sure that the peripheral is connected properly to the PC. Upon opening, click on the ‘Driver’ tab and then select ‘Update Driver’.

Make sure to refer to the system documentation that you received with your PC or computer to check for the motherboard details and driver specifics.

Method 3 – Use software to automatically download the driver

Manually uninstalling and reinstalling the driver will do the trick, however, it may be time-consuming especially when you would have to resort to your hardware user manual.

Therefore, using a program such as DriverFIX can save you a lot of time and frustration in having your device work properly on your computer.

DriverFIX, with its user-friendly approach to help you fix your PC issues, comes with an integrated database that detects which drivers you need to reconfigure within just a few seconds and downloads it automatically.

It further ensures that your drivers are installed in their entirety leaving no room for any incomplete files to remain that create Error Code 40.

It also has the added advantage of being able to backup and restores your files should there be the slightest possibility of system file damage.

Thus, registry damage can be averted by letting the software roll back the system files to an earlier healthy checkpoint. Driver Assist is the answer to fixing your PC error codes accurately and quickly.

Cannot start new hardware device, Error 49
In case you don’t know, the Windows Registry contains a System Hive which is a core part of Windows. The Windows operating system store various settings, options, and configurations. And if you encounter a Device Manager Error 49 for a device then it means that the system hive has exceeded its size limit. Worry not for this post will provide you with possible solutions that can help you in fixing error code 49. You will see the following error message when you encounter error code 49:
“Windows cannot start new hardware devices because the system hive is too large (exceeds the Registry Size Limit), (Code 49)”
There are instances when it may so happen that the device or devices are no longer attached to the computer but they are still listed in the system hive of the registry. For instance, if you were removing hardware and application for years but they weren’t removed from the registry then the size of the system hive keeps on growing until it hits the maximum limit. As you know, making changes in the registry manually, no matter how knowledgeable you are on such things is not sage since the registry is not only important but also complex. In addition, the System Hive is also a permanent part of the Registry associated with a set of files that contain information related to the configuration of the computer on which the OS is installed. To resolve this error, you must remove or uninstall any hardware devices that are no longer in the system. In fact, the Device Manager hides them by default so you need to enable hidden or non-present devices.

Fix Failed to transfer logged messages ...
One of the most common hardware issues with any PC usually has something to do with the hard drive so if your hard drive experiences some errors, you could end up losing a lot of important information that’s stored in your computer. This is why Windows provided users with the CHKDSK utility which helps in looking for bad sectors on the drive. However, there are times when the CHKDSK utility could also face issues like the following error:
“Failed to transfer logged messages to the log event with status 50.”
According to security experts, this error is most likely due to the hard drive or RAM being in a “Read-only” state. It could also be due to some physical issues with the hard drive. On the other hand, it could be that the system is prevented from creating logs by some drive, service, or malware. To fix this error, you have to check if the hard disk is writable. You could also try to run the CHKDSK utility in Safe Mode or you could also check the physical status of your hard disk or external drive.

Option 1 – Check if the hard disk is writable

Although the CHKDSK utility checks for bad sectors in the hard drive, it also has to create logs of the result. And as states in the error message, the CHKDSK utility is not able to log the logged messages. This kind of error occurs when the log can’t be written to an installation disk.

  • Log in as administrator and right-click on the system drive.
  • Select Properties and then go to the Security tab. Here, check if you are allowed to modify the drive. If not, click on Edit (as an administrator).
  • Now edit the permissions for the SYSTEM and Administrators group. Note that these are the only default settings for these two groups or usernames.
  • Then click on the Apply button save the changes made and exit.

Option 2 – Run the CHKDSK utility in Safe Mode

You could also try to run the CHKDSK utility in Safe Mode as this might solve the error.
  • Boot your computer in Safe Mode.
  • Next, open Command Prompt with admin privileges.
  • Then type and enter this command to execute it: chkdsk c: /f /r
  • Wait until the process is completed and boot your computer normally and then run the CHKDSK utility again and check if the “Failed to transfer logged messages to the log event with status 50” error is now fixed.

Option 3 – Try to check the hard disk or external drive physically

If the first two options didn’t work, you might want to check the physical status of your hard disk or external drive as the problem could root from there. You can try to tighten the wires that connect the hard disk to the motherboard. However, if it doesn’t help, you should seek out assistance from a hardware technician.

UEFI Firmware settings goes missing
When it comes to booting an operating system on a computer, one of the most essential pieces of software you can use is the UEFI. In fact, a lot of users now prefer to use UEFI instead of BIOS. It also depends on whether the UEFI or the BIOS is supported on the motherboard. Recently, a number of users reported an issue with UEFI where they were unable to find it under the Advanced Options screen where it’s supposed to be located. The missing UEFI Firmware settings in the Advanced Options could be caused by several reasons. It is possible that the access to the UEFI menu is blocked or it could also be due to the Extra Fast Startup feature being enabled. It is also possible that the operating system is installed in Legacy mode. There are several options to try to fix this issue. You need to check if your computer supports UEFI or you could also try to disable Fast Startup or bypass the Extra Fast Startup feature. You can also use a boot to UEFI shortcut as well as check the CMOS battery.

Option 1 – Try checking if your computer supports UEFI

The first thing you have to do is to verify if your computer supports UEFI. If your computer does not support UEFI, then it’s no wonder why you don’t see the UEFI Firmware settings in the Advanced Options.

Option 2 – Try turning off Fast Startup

  • First, boot your computer in Safe Mode.
  • Once your computer is booted in Safe Mode, tap the Win + R keys to open the Run dialog box and type in “control” to open the Control Panel.
  • Next, click on the Hardware and Sound section and click on Power Options.
  • Afterward, select the “Choose what the power buttons do” option from the left side menu pane.
  • Now click on Change settings that are currently unavailable and uncheck the entry that says, “Turn on fast startup (Recommended)”.
  • Then click on Save Changes and restart your computer and see if it has fixed the problem or not.

Option 3 – Try bypassing the Extra Fast Startup feature

As mentioned, the missing UEFI Firmware settings could be due to the Extra Fast Startup feature. To fix it, you have to disable this feature. All you have to do is tap and hold the Shift key and click on the Shutdown button from the Start button. This will boot your PC with the UEFI booting from the beginning and then use the hotkey for your motherboard to boot into the UEFI setup.

Option 4 – Try using a boot to UEFI shortcut

  • Right-click on any empty space on your Desktop and select New > Shortcut.
  • This will open a new mini window. And here, you have to type this in the text field: shutdown /r /fw
  • After that, click on Next and name the desktop shortcut and then click on Finish.
  • Next, right-click on the newly created shortcut and select Properties.
  • Click on the Advanced button and select the “Run as administrator” option.
  • Now click OK to save the changes made. Each time you execute this shortcut, your computer will automatically be booted to the UEFI Firmware Settings.

Option 5 – Try to check the CMOS battery

Another thing you can do is check the CMOS battery physically on the motherboard and see if it has to be replaced since a damaged CMOS battery can also cause the issue with the missing UEFI Firmware settings.

Option 6 – Set your computer from Legacy to UEFI

If applicable, you can try to set your computer from Legacy to UEFI to resolve the problem.
  • In the Windows Search box, type “command prompt” and from the search results that appear, right-click on Command Prompt and select the “Run as administrator” option.
  • After that, execute this command: mbr2gpt.exe /convert /allowfullOS
  • Now, wait until the process is completed since you can track its process on your screen.
  • Once it’s done, go to Settings > Update & Security > Advanced Startup options and from there, click on Restart Now. This will restart your computer and give you advanced options.
  • Next, select Troubleshoot > Advanced Options where you will see further options including System Restore, Startup Repair, Go back to the previous version, Command Prompt, System Image Recovery, and UEFI Firmware Settings.
  • Now select the UEFI Firmware Settings. This will take you to the BIOS. Boot Mode is typically available under Boot > Boot Configuration. Once you’re there, set it to UEFI and then save the changes you’ve made. After that, your computer will restart.

Driver state power failure error can be linked to three things happening in your computer. Incorrect power settings, driver issues, or incompatible hardware. Sadly when this error happens you only receive a blue screen of death with this message: Blue screen of death driver power state failureSadly receiving this blue screen does not really explain which of the three cases is the correct one and causing the unwanted issue. That being said, this article will not offer you a direct solution this time, it will be more like a guide on what to check and to do in order to remove this error, reason for this is the nature of the error itself. If your computer is booting properly and you can enter Windows without issues the first thing you can try is going into power options and set it to high performance, if you are on a laptop set high performance both ways, when plugged and when on battery. Power performance settings can reflect on some hardware and can cause mayhem. After setting reboot the computer and see if the error repeats itself. If the error persists go to the device manager and see if there is hardware that has any kind of warning beside it. If there is, update the driver or remove the driver of the device to see if this fixes the issue. If all of the previous two things fail there is another thing you could try. Turn off your computer and disconnect all hardware except the most basic one. Now, this may take a long period of time but boot your computer and then repeat this process but each time add a new piece of hardware to eliminate and find which one is causing the issue. When found try to see if it is repairable through driver updates or get a new device.
