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.

How to remove ListenToTheRadioNow from your PC

ListenToTheRadioNow is a Browser Extension that allegedly lets you listen to radio from your browser. However, all this extension does is add links to the popular radio stations on your home page. This extension hijacks your home page and changes your default search provides to MyWay. While running it monitors browsing data from your browser, mining information such as website visits, clicked links, and sometimes even personal information. This information is later used to display targeted ads through your browser. Several anti-virus scanners have marked this extension as a possible Browser Hijackers, and due to its data mining nature, it is not recommended to keep it on your computer.

About Browser Hijackers

Browser hijacking is a type of unwanted software, commonly a browser add-on or extension, which then causes modifications in the web browser’s settings. Browser hijackers could do more than just modifying homepages. In most cases, browser hijacking is used for earning ad revenue that comes from forced advert clicks and website visits. Even though it may seem naive, all browser hijackers are dangerous and therefore always regarded as security threats. They don’t just ruin your internet browsers, but browser hijackers could also modify the system registry to make your PC susceptible to other malicious programs.

How you can know whether the browser is hijacked?

There are several symptoms of browser hijacking: 1. home-page is changed 2. new bookmarks pointing to porn websites have been added to your bookmarks 3. the default internet search engine and/or the default web browser settings are altered 4. find new toolbars that you did not add 5. unstoppable flurries of popup ads show up on your PC screen 6. webpages load very slowly and often incomplete 7. you have prohibited entry to certain web pages, for example, the site of an anti-malware software firm like SafeBytes.

So how does a browser hijacker infect a PC

A browser hijacker could be installed on your computer or laptop if you visit an infected website, click on an e-mail attachment, or download something from a file-sharing website. They also come from add-on programs, also referred to as browser helper objects (BHO), browser plug-ins or toolbars. Also, some shareware and freeware can put the hijacker inside your computer through “bundling”. A good example of some popular browser hijackers includes Babylon, Anyprotect, Conduit, SweetPage, DefaultTab, Delta Search, and RocketTab, but the names are regularly changing.

Tips on how to get rid of a browser hijacker

Some hijackers can be removed by uninstalling the freeware they were included with or by eliminating any extension you’ve recently added to your computer. However, most hijacking codes are not very easy to eliminate manually, since they go deeper into your operating system. Furthermore, manual removal expects you to perform several time-consuming and tricky actions that are hard to do for new computer users. Professionals always recommend users to get rid of any malicious software including browser hijacker with an automatic malware removal tool, which is simpler, safer, and faster than the manual removal technique. One of the top tools for correcting browser hijacker malware is SafeBytes Anti-Malware. It can help you eliminate any pre-existing malicious software in your computer and provides you real-time monitoring and protection from the latest internet threats. Employ a PC optimizer along with your anti-malware software to correct various registry problems, remove computer vulnerabilities, and improve your computer overall performance.

Help! Malware Preventing Antivirus Installation And Access To The Internet

All malware is bad, but certain kinds of malware do a lot more damage to your computer than others. Some malware sits in between the computer and the net connection and blocks some or all internet sites that you want to check out. It will also prevent you from installing anything on your system, especially anti-virus applications. If you’re reading this, chances are you’re stuck with a malware infection that is preventing you to download and install the Safebytes Anti-Malware program on your computer. Do as instructed below to get rid of the malware by alternate methods.

Install the anti-malware in Safe Mode

Safe Mode is actually a special, basic version of Windows in which just minimal services are loaded to counteract viruses and other troublesome programs from loading. In the event, the malicious software is set to load automatically when the computer boots, switching to this mode may well prevent it from doing so. To start the computer into Safe Mode, hit the “F8” key on your keyboard just before the Windows logo screen comes up; Or right after normal Windows boot up, run MSConfig, check Safe Boot under Boot tab, and click Apply. Once you’re in Safe Mode, you can attempt to download and install your antivirus software application without the hindrance of the virus. After installation, run the malware scanner to get rid of most standard infections.

Download the security program using an alternate web browser

Some malware mainly targets particular browsers. If this sounds like your case, use another web browser as it could circumvent the virus. If you appear to have a virus attached to Internet Explorer, then switch over to an alternate browser with built-in security features, such as Firefox or Chrome, to download your preferred anti-malware program – Safebytes.

Install and run anti-virus from the Thumb drive

Another solution is to store and operate an anti-malware program entirely from a Pen drive. Do these simple steps to clear up your affected PC using a portable antivirus. 1) Download the anti-malware on a virus-free PC. 2) Insert the USB drive onto the same system. 3) Run the setup program by double-clicking the executable file of the downloaded software, with a .exe file format. 4) Choose the drive letter of the pen drive as the place when the wizard asks you where you would like to install the antivirus. Follow the instructions on the computer screen to complete the installation process. 5) Unplug the pen drive. You may now utilize this portable anti-virus on the affected computer. 6) Double-click the EXE file to open the Safebytes software right from the pen drive. 7) Click the “Scan” button to run a full system scan and remove viruses automatically.

Cortana can’t connect to the Internet
One of the most sophisticated Artificial Intelligence or AI assistants there is in the market is Cortana. However, no matter how sophisticated this AI assistant may be, there are still times when you encounter issues with it. So if your Cortana is not connecting to the internet, worry not for this post will guide you in fixing the problem. This connection issue in Cortana might have something to do with the settings, network connectivity, or your Microsoft account. In addition, it could also be that the Firewall or antivirus program interferes with its connection. Whichever the case is, here are some possible solutions that could help you resolve the problem.

Option 1 – Try to power cycle the modem, router, and computer

  • Connect the modem, router, and the PC hard-wired and then switch all of these three devices off.
  • Turn on the modem and wait for 30 seconds.
  • Turn on the router and wait for 30 seconds as well.
  • Finally, turn on the computer and check if you can now successfully connect to the internet.

Option 2 – Check if your router or ISP is properly working

Since the basis for this issue is that Cortana is not connecting to the internet even though you are able to access websites using your browser, you might want to check your router or ISP (Internet Service Provider) and see if they’re functioning properly.

Option 3 – Try changing your internet connection

You can also try changing your internet connection and see if it fixes the problem. If you are using Ethernet, you can try connecting to a Wi-Fi connection and see if Cortana is able to connect or not.

Option 4 – Try to run the Search and Indexing troubleshooter

You might also want to run the Search and Indexing troubleshooter in Windows 10 as it checks whether the settings for Cortana are in place and automatically corrects any issues if the update or software installation has changed the settings. To run it just click on the Start button and select Settings > Updates and Security > Troubleshoot. From there, select the Search and Indexing Troubleshooter. Note: You can also run the Network Troubleshooter as it can also help in resolving the issue especially if the problem is in the network.

Option 5 – Try to remove Proxy

  • Tap the Win + R keys to open the Run dialog box.
  • Then type “inetcpl.cpl” in the field and hit Enter to pull up the Internet Properties.
  • After that, go to the Connections tab and select the LAN settings.
  • From there. Uncheck the “Use a Proxy Server” option for your LAN and then make sure that the “Automatically detect settings” option is checked.
  • Now click the OK and the Apply buttons.
  • Restart your PC.
Note: If you are using a third-party proxy service, you have to disable it.

Option 6 – Verify your Microsoft account

In some cases, Cortana might not be able to connect to the internet because your Microsoft account is no longer verified. This usually happens when you use a two-step authentication system with your Microsoft account. To verify it, just open Settings and click on Accounts. After that, check if you have a Verify hyperlink under your Microsoft account or not then click on Verify. Afterward, follow the next on-screen prompts to verify your Microsoft account. Once your account is verified, restart your computer.

Option 7 – Try resetting Cortana

  • Open Cortana and go to the Settings section where you’ll see the “Turning off Cortana clears what Cortana knows on this device, but won’t delete anything from the Notebook. After Cortana is off, you can decide what you’d like to do with anything still stored in the cloud” option. Turn this option off.
  • Restart your PC.
  • After your computer boots, launch Cortana again and check.

Option 8 – Try to reinstall Cortana

If none of the options given above works, you must consider reinstalling Cortana.
  • First, right-click on the Start button and click on the Windows Powershell (Admin) option from the list.
  • Next, type the following command and hit Enter to execute it:

Cannot find the MS Software License Terms
Both the Windows 10 and Windows Server operating systems have a number of common system files that vary from the ones that support the installation, boot process, and other operations or tasks in the system. However, if any of these files get corrupted, it might cause some errors during the setup of the Windows 10 operating system. One of these errors is the “Windows cannot find the Microsoft Software License Terms” error.
“Windows cannot find the Microsoft Software License Terms. Make sure the installation sources are valid and restart the installation.”
The only option given when you encounter this error is to click on the OK button and nothing else and then the setup gets interrupted and won’t push through. To fix this error and proceed with the installation, you can try to get a new installation image or switch ports, or fix the CFG file. For more details, follow each one of the potential fixes provided below.

Option 1 – Try to get a new installation image

It is possible that there might be some issues with the installation image. It could be corrupted or was modified illegally. Or it could be that the bootable storage device created might have damaged sectors or installation. To resolve this problem, you need to download a fresh copy of the Windows 10 installation image using the Windows Media Creation tool or simply use the ISO image separately and then build a bootable USB.

Option 2 – Try to switch Ports

The error might be caused by the connection to the USB port. It could be that the port is unstable due to a number of factors that resulted in the interruption of the installation process. To fix this problem, you can try switching the USB port or if you are using an optical drive, you can get an external USB optical drive or connect it to another port internally and see if it fixes the problem.

Enumerating user sessions to generate ...
There are times when the Windows Search doesn’t work and you wouldn’t have a clue as to why it happened since it does not give any error codes. In such cases, you have to check the error logs in the Event Viewer to find out more about the problem. From there, look for an error with the Event ID 3104 in the Windows error logs and if you see an error message that says, “Enumerating user sessions to generate filter pools failed”, read on as this post will guide you in fixing the problem. Apart from the error message, you might also see more information in the details section of the log that says, “(HRESULT: 0x80040210) (0x80040210)”. This kind of error is most likely caused by something that prohibits the search function from initializing. A lot of users assumed that it could be due to Cortana but it’s actually not. While some users also reported that they encounter the issue after they restarted their computers. This error was also reported with the same event ID 3104 on the Windows Server. According to security researchers, this error could be caused by problems in the Registry entry of Windows search. It could also be due to an issue with the SYSTEM account where it hasn’t been added to the DCOM Security. It is also possible that the Windows Search function has not been initialized. To fix this error, you can try to rebuild the Search Index manually or run the Search and Indexing troubleshooter. You can also check the startup type of the Windows Search service or try some registry tweak.

Option 1 – Try to rebuild the Search Index manually

The first thing you can do to fix the problem is to manually rebuild the Search Index. You can do that by going to Control Panel > Indexing Options and from there, click on Advanced. After that, go to the Index Settings tab and then click on Rebuild > OK. Once you’re done, check if it fixed the problem.

Option 2 – Try running the Search and Indexing troubleshooter

You could also run the Search and Indexing troubleshooter in Windows 10 as it checks whether the settings are in place and automatically corrects any issues with the Windows 10 search function. To run this troubleshooter, just click on the Start button and select Settings > Updates and Security > Troubleshoot. From there, select the Search and Indexing Troubleshooter. Once the troubleshooter is done, restart your computer and see if it fixed the error.

Option 3 – Try checking the startup type of the Windows Search Service

In this option, you have to check the startup type of the Windows Search service since the service won’t start. To do so, refer to these steps:
  • Tap the Win + R keys to open the Run utility and type “services.msc” in the field and then tap Enter to open the Services Manager.
  • Next, from the list of services, look for the Windows Search Service or WSearch. Once you find it, right-click on it and select Properties.
  • After that, change the Startup type to Automatic and click on the Start button if the service is in the Stop state.
  • Now click on the Apply and OK buttons to save the changes made and then restart your computer.

Option 4 – Try changing the Registry entry for Windows Search

Before you apply some registry tweak, you need to create a System Restore point first. Once you have that covered, follow these steps:
  • Tap the Win + R keys to open the Run utility and type “Regedit” in the field and tap Enter to open the Registry Editor.
  • If a User Account Control prompt appears, just click Yes to proceed.
  • After opening the Registry Editor, navigate to this registry path: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows Search
  • From there, click on Windows Search and look for the key named “SetupCompletedSuccessfully” and change its value to “0”. Just right-click on it and select Modify.
  • Then input “0” as its value data and click on OK to save the changes made.

Ordinal not found, dynamic link library Error
If you encounter an error message saying, “The ordinal xxx could not be located in the dynamic link library C:/Program Files (x86)/Microsoft VS Code Insiderscode – insiders.exe“ and you see a reference of a missing DLL file, then this indicates that the software is trying to locate the related DLL file, however, it is missing, hence the error. The error mentioned “Ordinal” which refers to the order of a number mathematically, e.g. 1st, 2nd, etc. And in this error message, the ordinal is referring to an Xth file of an XX.DLL file which is missing which is why you’re getting this kind of error. When you get this particular error, it means that your computer is missing the Microsoft Visual C++ Redistributable program. As per the error message, XXX is a number that in turn is the Ordinal. There is also another common error related to Ordinal which says, “The ordinal 12404 could not be located in the dynamic link library mfc90u.dl”. The error message could be referring to any DLL in the message. And since all these DLL files are part of the package, the error changes quite a bit as the Visual Studio looks for that DLL file. To fix this error, here are some suggestions that might be of help.

Option 1 – Try installing Microsoft Visual C++ Redistributable

As pointed out earlier, the error pops up when the Microsoft Visual C++ Redistributable program is missing on your computer. Thus, you need to download it from the official website of Microsoft. Once you’ve downloaded the Microsoft Visual C++ Feature Pack Redistributable Package, install it and then check if the error is now fixed.

Option 2 – Try to install OpenSSL

If you encounter the same error message but it points out that the LIBEAY32.DLL file is missing, then you have to install OpenSSL. In such a case, you will see the following error message:
“Ordinal not found. The Ordinal [Xxxx] could not be located in the Dynamic Link Library Libeay32.dll.”
 Make sure that when you install OpenSSL, you do it into the Windows system directory since the Libeay32.dll file is related to security.

Option 3 – Try to check Windows Updates

There are instances when Microsoft rolls out the framework and related updates via Windows Updates. It could be that an update related to DLL is still pending which is why you need to check Windows Updates. To do so, go to Settings > Update and Security and from there check if there is any pending update. If there is, you need to install that update and then restart your computer if needed.
