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.

Creating custom Keyboard shortcuts in Windows
Keyboard shortcuts are undeniably one of the most utilized ways and are helpful in maximizing productivity through the various applications at top speed in Windows 10. It offers the option to create custom keyboard shortcuts that allow users to launch apps, and even websites, instantly. There are already tons of keyboard shortcuts that are built-in in Windows 10 but in case you don’t know, you can actually create new ones. Doing so is not a difficult task and in this post, you will be guided on how you can exactly create custom keyboard shortcuts in your Windows 10 computer. Most users would create desktop shortcuts or pin the apps in the taskbar to speed up the process of working on their computers. It is an easy task to do since you can easily do it by dragging an app from the Start Menu to the desktop or by simply right-clicking on the executable app and selecting the “Create Shortcut” option. However, doing so would take physical effort and there are times when you have to minimize all the apps to get to the desktop so you can click the shortcut and this is where the Custom Keyboard Shortcuts come in handy. You can create Custom Keyboard Shortcuts in Windows 10 for various programs – from the traditional desktop apps to the new universal apps – you can fling in a shortcut so that you can instantly open them faster compared to when doing it manually and besides this also wouldn’t affect any of the ongoing system activity. To get started, you need to follow the steps provided below carefully.

To add Custom Keyboard hotkeys to a program and website desktop shortcuts, here’s what you have to do:

Step 1: First, you have to right-click on the app or website and select Properties. Step 2: After that, go to the Shortcut tab and from there, you will see the “Shortcut key” textbox which allows you to enter a new or custom keyboard shortcut for the app or website. Step 3: In the textbox field, input your preferred letters to set up the new hotkey. Keep in mind that this custom shortcut has to be combined with the Ctrl + Alt keys which means that if you want to select “N”, you have to tap the Ctrl + Alt + N keys. Step 4: Once done, click on the Apply and OK buttons to save the changes made and then close the window. Step 5: After that, tap the newly created keyboard shortcut, Ctrl + Alt + N keys again to open the app or website you’ve set up earlier.

To add Custom Keyboard hotkeys to a desktop app or an independent program that can be installed using direct download, here’s what you have to do:

Step 1: First, open the Start Menu and look for the icon/tile of the required app in the menu. However, if you are not able to find the desired app, then just click on the All Apps option to navigate through all the apps that are installed on your PC. Step 2: Once you find the app, just right-click on it and select More and then click on the “Open file location” option. Step 3: This will open a new window with the shortcut icon. Right-click on the app’s shortcut icon and select Properties. Step 4: This will open the Properties window where you can add the shortcut combination. Keep in mind that just like the previous method, the custom shortcut has to be combined with the Ctrl + Alt keys. For instance, if you select E, then you also have to set a keyboard shortcut that includes Ctrl + Alt, so it will be, Ctrl + Alt + E. Step 5: Once you’re done, click on the Apply and OK buttons to save the changes made. You should now be able to use the custom shortcut key you’ve set.

Reversing Mouse & Touchpad scrolling direction
As you know, aside from making computing a lot easier, mouse and touchpad, it also makes computing more efficient and less time-consuming. And so life is unimaginable without these useful devices. However, it is a known fact that you can’t customize these devices since all touchpads and mice come with their own default scrolling direction but worry not for in this post you will be guided on how you can reverse their default scrolling directions. Every user has their own different preferences when it comes to scrolling directions. You might want the scrolling directions to look like the page is being scrolled in the same direction in where you move your fingers over the touchpad or you might prefer it in an inverted way. Reversing the scroll direction for your device’s touchpad is really easy as Windows by default offers this customization. So if you are trying to find a way to reverse the scrolling direction of your mouse, then you have to follow a tricky little method which will be provided in this post. It is apparent from the number of settings the touchpad is available that it has become more customizable. You can configure everything, from its gestures, taps, sensitivity, and even its scrolling direction. And now, if you want to reverse its scrolling direction, here’s what you have to do: Step 1: Tap the Win + I keys to open Settings. Step 2: From there, go to Devices and select Touchpad from the menu. Step 3: Next, look for the Scrolling Direction setting. Step 4: Then click on the drop-down and select your preferred setting.  If you want the same direction scrolling, just select the “Downwards motion scrolls down” option, and if you want the opposite select the other one. After you carry out these steps, the settings will be applied right away and you will see the changes. On the other hand, if you want to change the scrolling direction for your mouse, the procedure is not as simple as it was for the touchpad.

To reverse the scrolling direction for a mouse, refer to these steps:

Step 1: In the Start Search, type “device manager” and click on the appropriate result to open the Device Manager. Step 2: After opening the Device Manager, look for your Mouse under the “Mice and other pointing devices” section. It is mostly listed as an “HID-compliant mouse”. Step 3: Right-click on your mouse and click Properties. Step 4: From there, go to the Details tab and from the drop-down menu, select Device Instance Path. Step 5: Now take note of the value displayed on its value field and then tap the Win + R keys to open the Run dialog box. Step 6: Type in “Regedit” in the field and hit Enter to open the Registry Editor. Step 7: Next, navigate to the following location:
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetEnumHID
Step 8: From this folder, you have to start matching the values in the first part of the value you’ve taken note of. Step 9: Open the folder which has the same value and repeat this for the second part of the value. Step 10: Afterwards, click on the Device Parameters and look for a property named “FlipFlopWheel” and invert its value from 0 to 1 or 1 to 0 to reverse the scrolling direction. And then restart your PC to apply the changes made. After you restart your PC, you should see the changes in the scrolling direction of your mouse. Note that you can change the value back to its original value or just use the registry backup to undo the changes you’ve made.
