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.

Windows 11 vs Windows 10: Main Differences

Still sitting on the fence about upgrading to Windows 11 because you don’t know what to expect? Interestingly, the new edition somehow manages to be both a total revamp and still very similar to its predecessor in many ways. It’s really something to experience for yourself.

We do want to give you a sneak peek, though. So here’s an overview of the biggest changes Windows 11 brings to the table.

What’s different in Windows 11?

1. Visual changes

The first thing anyone will notice after switching to Windows 11 is the striking visual difference. The entire interface is smoother, cleaner and more minimalistic than on Windows 10, even resembling the macOS in some instances.
Perhaps the most obvious change in appearance is the Start menu and Taskbar location, which is now at the bottom center. It’s actually very neat, but if you’re someone who loves familiarity, don’t worry, you can move it back to the left.

Centralized Taskbar and Start menu

Moreover, you’ll notice that the Taskbar includes a Microsoft Teams icon by default (which you can, of course, remove) and that Live Tiles are gone. The News and Interests section has also been removed - or, shall we say, replaced. As opposed to Windows 10, news, weather forecasts and other information are now displayed as widgets.

To add to the cleanliness of the UI, Microsoft also enhanced the ‘Snap Layouts’ feature to help you better organize your windows and maximize screen real estate. It’s similar to app grouping on your smartphone. In Windows 10 this feature is slightly restricted, as it requires some manual resizing and dragging. In Windows 11, you can just hover over the minimize/maximize option on a window, select a layout and throw the windows in there.

2. New accessibility features

Microsoft has certainly paid attention to accessibility with Windows 10, but Windows 11 takes this to a whole new level.

One of the ways Windows 11 has taken things up a notch is by adding the long-awaited ‘Live Captions’ feature and advanced Narrator options.

Live Captions apply both to media played on your PC as well as your own speech when you’re using the microphone. Keep in mind that, as with almost all kinds of subtitles, you have to be prepared for a potential delay. However, it’s barely noticeable and doesn’t take away from the usefulness of this awesome new feature whatsoever.

As for the Narrator, there are three new voice packs to choose from. Microsoft has tried to put emphasis on a more natural voice than we are used to. So, now you can choose between Aria, Jenny and Guy, who will read pretty much anything off your screen out loud. Aside from this, Microsoft has also expanded the list of braille displays supported by the Narrator feature. 
For users with anxiety or trouble concentrating, a welcomed addition is the Focus app, which is no longer part of the Clock app. It’s now separate and called ‘Focus Sessions’, automatically triggering the Do Not Disturb mode when activated. It blocks all pop-ups and flashes and lets you work in peace until you’re ready to switch it off.

3. Android apps

Android users may rejoice! Windows 11 supports the use of your favorite applications now. 

Microsoft has done this by integrating the Amazon Appstore to the Windows 11 Microsoft Store. From there, you can download your favorite Android apps and use them on your PC in a smartphone-like window.

Unfortunately not too many apps are supported at this time, but Microsoft is working on making the emulation possible for many more. Also, the option is only available in specific regions at this moment - check out if you’re one of the lucky ones.

4. Improved gaming performance

Avid gamers will be happy to hear that Microsoft has put some effort into streamlining Windows 11 for their gaming needs.

To give gamers a supreme visual experience, Windows 11 offers the ‘Auto HDR’ feature. As long as your monitor is HDR-compatible, this feature will automatically adjust the colors, brightness and contrast of games without any input from you. 

Another update is DirectStorage, which we were introduced to in Windows 10 already. In Windows 11, it’s been improved to tweak loading times and overall gaming performance efficiency even better. The predisposition for it to work optimally is that your device has an NVMe SSD. 

The Xbox Game Bar also helps gamers towards a smoother experience. It allows in-game screenshots, viewing processes that are running (similar to the Task Manager), monitoring the CPU and GPU performance and frame rate, integrating the Xbox App and more. There’s also a number of widgets you can now use with the Game Bar, for example the Spotify widget.

Another cool addition is the Xbox Game Pass, which unlocks hundreds of games to play on your Xbox App, with new additions coming in every month.

5. Smart App Control

Aside from a sleek new look and better accessibility for all users, Windows 11 also comes with a security power-up. Bear in mind that this feature is only available on clean Windows 11 installs. 

Smart App Control (SAC) is an AI-powered new feature designed to protect your PC from potential threats. It blocks untrustworthy apps and adware and helps detect potentially unwanted apps, maintaining your PC’s performance and keeping your system safe.

It comes with an ‘Evaluation’ mode, which you should definitely select when running SAC for the first time. That way, the app monitors your usage and assesses whether you’re a candidate for SAC. Some users need it to be on all the time, for others it might be too distracting. Evaluation mode will turn SAC on or off based on your usage.

Don’t disable SAC again unless you’re absolutely sure you don’t need it, since reenabling it will require a fresh install. We recommend you don’t turn it off, as it is a neat feature protecting your data and files from malware at all times.

Summary

Have we piqued your interest in trying Microsoft’s latest OS? It’s a pretty exciting new iteration, but we’ll let you find out for yourself. We hope you like it!

The information that is sent back to the servers contains your browsing data & visited web pages. As a result, Polimva is considered a potentially unwanted browser hijacker and if flagged for optional removal.

About Browser Hijackers

Browser hijackers (also known as hijackware) are a kind of malware that modifies internet browser settings without the computer owner’s knowledge or approval. These kinds of hijacks appear to be rising at an astonishing rate worldwide, and they could be truly nefarious and often harmful too. They are designed to disrupt browser functions for many different reasons. It redirects you to the sponsored websites and injects adverts on the browser which helps its developer generate ad revenue. Even though it might seem naive, all browser hijackers are damaging and therefore always regarded as security threats. What’s more, hijackers could make the entire infected system vulnerable – other destructive malware and viruses will grab these opportunities to get into your computer system effortlessly.

Indications of browser hijack

Here are some signs that suggest you’ve been hijacked: 1. your browser’s home page is reset to some unfamiliar webpage 2. bookmark and the new tab are also modified 3. the default web browser configurations have been changed and/or your default web engine is altered 4. you see multiple toolbars on your web browser 5. your internet browser displays endless pop-up windows 6. your internet browser starts running slowly or displays frequent errors 7. you’re disallowed access to certain websites, for example, the website of an antimalware software manufacturer like SafeBytes.

Exactly how browser hijacker infects PCs

Browser hijackers can enter a PC in some way or other, including via downloads, file sharing, and email also. They can also come from any BHO, extension, add-on, toolbar, or plug-in with malicious purpose. Some internet browser hijackers spread in user’s PC by using a deceptive software distribution method called “bundling” (generally through freeware and shareware). Some of the popular hijackers are Polimva, Conduit Search, Babylon Toolbar, OneWebSearch, Sweet Page, and CoolWebSearch.

The best ways to remove a browser hijacker

Some browser hijacking could be simply corrected by finding and removing the corresponding malware software from your control panel. Unluckily, many of the software applications used to hijack an internet browser are deliberately built to be difficult to remove or detect. You should think of doing manual fixes only if you’re a tech-savvy person since there are possible risks associated with tinkering around with the computer registry and HOSTS file. You can opt for automatic browser hijacker removal methods by simply installing and running an efficient anti-malware program. If you need to get rid of persistent hijackers effectively, install the top-rated, award-winning anti-malware software Safebytes Anti-Malware.

Malware Blocking Internet And All Anti-Malware Software? Do This!

Malware could cause many different types of damage to computer systems, networks, and data. Some malware variants alter browser settings by adding a proxy server or modify the PC’s DNS settings. In such cases, you will be unable to visit certain or all of the websites, and thus unable to download or install the required security software to eliminate the malware. So what to do when malicious software prevents you from downloading or installing Safebytes Anti-Malware? There are a few steps you can take to circumvent this issue.

Use Safe Mode to fix the issue

Safe Mode is a special, simplified version of Microsoft Windows where just bare minimum services are loaded to counteract viruses and also other troublesome applications from loading. In case the malware is set to load immediately when the computer starts, shifting into this mode may well prevent it from doing so. In order to get into Safe Mode or Safe Mode with Networking, press F8 while the computer is starting up or run MSConfig and find the “Safe Boot” options in the “Boot” tab. Once you are in safe mode, you can attempt to install your anti-malware software application without the hindrance of the malicious software. Now, you could run the anti-virus scan to eliminate viruses and malware without any interference from another application.

Switch over to a different browser

Certain malware might target vulnerabilities of a specific web browser that block the downloading process. In case you suspect that your Internet Explorer has been hijacked by a trojan or otherwise compromised by cybercriminals, the ideal thing to do would be to switch to an alternate browser such as Mozilla Firefox, Google Chrome, or Apple Safari to download your chosen computer security software – Safebytes Anti-Malware.

Install security software on a thumb drive

To successfully eliminate the malware, you might want to approach the issue of running an anti-malware software program on the affected computer system from a different angle. Follow these steps to run the anti-malware on the infected computer. 1) Download the anti-malware on a virus-free PC. 2) Plug in the pen drive to a USB slot on the clean computer. 3) Run the setup program by double-clicking the executable file of the downloaded software, with a .exe file format. 4) Choose a USB flash drive as the location when the wizard asks you exactly where you want to install the program. Follow the instructions on the computer screen to finish off the installation process. 5) Now, plug the pen drive into the corrupted computer. 6) Double-click the EXE file to run the Safebytes software from the thumb drive. 7) Click on “Scan Now” to run a scan on the infected computer for viruses.

Method One:  Use the Windows Update Troubleshooting Tool to Resolve the Issue

When an error arises during the Windows Update process on Windows 10, the best solution is often to use the built-in tool provided by Microsoft, the Windows Update Troubleshooter. An option to open this tool often appears when the error message itself appears.

By running this tool, your system will attempt to scan the files involved in the Update process to try to determine where the conflict or error may be occurring. If one of the system files needs to be repaired or downloaded again, this tool can often resolve the issue on its own.

If the Troubleshooter tool successfully fixes the error, be sure to restart your computer before attempting to run the Update process again so that you can fully apply any changes that have been made.

In some cases, however, the Troubleshooter tool will not be able to find the problem or will be able to identify what the issue is, but not able to fix it. If this happens, it may be time to turn to Method Two.

Method Two:  Manually Perform a Reset on Windows Update Assets

To manually reset the assets associated with the Windows Update tool, follow these steps:

  • Step One: Open up the command prompt from the start menu and select the option to run it as an administrator.
  • Step Two: Run the following commands, hitting the enter key after each is put in:
    • Net stop wuauserv
    • Net stop cryptSvc
    • Net stop bits
    • Net stop msiserver
    • Ren C:\Windows\Software\Distribution Software\Distribution.old
    • Ren c:\Windows\System32\catroot2\Catroot2.old
    • Net start wuauserv
    • Net start cryptSvc
    • Net start bits
    • Net start msiserver
  • Step Three: Type in the word “exit” to quit out from the Command Prompt.

Once these steps are done, you can try to use the Windows Update tool again to see if the problem has successfully been resolved.

Method Three: Use An Automated Tool

If you wish to always have at your disposal a utility tool to fix these Windows 10 and other related issues when they do arise, download and install a powerful automated tool.

This kind of error could be caused by several factors. It could be due to your antivirus program or other third-party programs installed on your computer. It is also possible that the installation of the Microsoft .NET framework id corrupted or some of its installation files are corrupted. Thus, to fix the error, there are a few suggestions you need to follow such as:

Option 1 – Try to temporarily disable your anti-virus program

As mentioned, the error could be due to the antivirus program or the Windows Defender Firewall installed on your computer. Thus, disabling them or any security software installed in your computer is always a good idea you can try when you’re not able to access the shared drive in your computer. There are times when you encounter problems like the “Unhandled exception has occurred in your application” error due to interference of antivirus or security programs. Thus, you have to disable both your antivirus program in the meantime and check if it fixes the error or not.

Option 2 – 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 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.)
  • Once your computer has restarted, check if the error is now gone. If it is, then the culprit is some third-party program. Thus, you have to enable the third-party programs one by one to find out which one of them is causing the the “Unhandled exception has occurred in your application” error.

Option 3 – Try to run a System File Checker scan

System File Checker or 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 that might be the cause why you’re getting the “Unhandled exception has occurred in your application” error. To run the SFC command, follow the steps given below.
  • Type “cmd” in the Start search and then right-click on the appropriate search result.
  • Next, select “Run as administrator” to open Command Prompt with admin privileges.
  • 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.
  • Now restart your computer and see if the problem is fixed or not.

Option 4 – Install and update Dependencies

There are times when programs and applications need to have drivers and supporting software installed for them to properly work. Although the installation usually takes care of it, it’s time for you to do some manual check especially if you are getting this issue of abnormal program termination.
  • Install some qualified drivers – A number of high-end games and applications need to have correct and valid drivers for them to work. They just don’t work with general drivers though. Microsoft has this Windows Hardware Quality Labs testing also known as WHQL testing which makes sure that drivers meet the correct experience and pass through the proper testing before certification. Thus, when installing drivers, you need to ensure that they are qualified drivers for your Windows 10 PC.
  • Download and install or Update DirectX – As you know, Microsoft DirectX is a suite of technologies developed by Microsoft to provide hardware acceleration for heavy multimedia applications like HD videos and 3D games. Since you are using Windows 10, you have the DirectX 12 version while the earlier Windows versions use the DirectX 11 version.
  • Install the Microsoft DirectX End-user runtime – The Microsoft DirectX end-user runtime gives updates to version 9.0c as well as previous versions of DirectX. To install it, click on this link and download it.
  • Update or install the .NET framework – The .NET framework is used by games and applications during development which means that without the runtime files that are installed in your computer, it definitely won’t work. Thus, you need to install or update this framework. You can also use the .NET setup verification tool to verify it.
