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.

Fixing errors, manually vs automatic

Encountering errors is never a pleasant experience and fixing errors can sometimes take a large amount of time. Also depending on your expertise and knowledge about computers and the operating systems themselves could be determining factor would you try to wrestle with error.

error fixing on computer

We will explore and analyze the advantages of both methods so you can choose and know when to apply one and when to reach for the other.

Advantages of manual method

Full control is the main advantage of manually solving errors, when you go deep dive into manually fixing problematic issues you are one that has control. Complete freedom is also another, sometimes fixing things can be done in several different ways and when you are the man behind the wheel, you are the one that can choose how to approach and what solution to apply in order to solve the issue.

Disadvantages of using manual method

The main disadvantage that some users might encounter is that they will need to know ins and outs of computer and operating systems' workings. Of course, the more complicated errors, the more knowledge it will require in order to apply the proper fix. There is also a risk to break something else if the person that is doing the fixing is not fully competent so this is also something to think about.

Another thing that goes against manual fixing is the time it will require in order to actually fix it, some more complex stuff will probably depend on searching for some external resources like searching for compatible drivers for example, or navigating complex registry keys inside Windows.

Advantages of automatic solutions

If you are a user that has no knowledge about how the operating system works, if you do not know what is a registry or how to properly navigate through the Windows folder then the automated solution is for you. The main advantage of automated systems is that you can easily fix errors without any kind of technical knowledge and usually with just one click of a button.

Saving time is also one of the advantages of fully automated solutions because they will work much faster than manually locating the problem and then fixing it. Also, most of these systems will have in place active monitoring that will check always if your system is in top form and alert you when something is not right.

Disadvantages of one-click solutions

Automated solutions are great, they can solve various issues and errors without any knowledge from the user, but they are not perfect. Like security suites sometimes an automated system can misinterpret something as an error when in fact it is not and fixing it could mean some apps not working anymore, luckily you can choose would you like to apply the suggested solution. So if you are using one do not just click fix without looking at what it is trying to fix and maintain.

Another problem with this is the price it is carrying, manually solving your computer error will cost you your time and knowledge but good automated software will come with a price tag. Some people might not be too happy to pay for this kind of application but at the end of the day, it will still be cheaper than a professional technician. The last thing that you should be aware of is that in order for the app to do its work properly it will need to be active all the time, now for modern computers, this is not the issue but for some older ones with a small amount of memory might lead to some slowing them down. This is a price to be paid in order to have your system always errors free.

Should you use an automated solution at all?

This depends on your knowledge and time available, professional IT technicians will not need this type of solution nor will power users but for most common people this will offer computers free of errors for an affordable price.

IW Unicorn and Scorpion PC Chair cockpits
Recently on errortools.com, we were talking about Cooler Master’s Orb X gaming chair that is an absolute beast and an amazing product. One downside of Orb X is its price. IW product line is somewhat competing with Orb X with a much more affordable price aiming to probably take customer base with lower income but offering them a great experience as well. The first thing you will notice is a different design and somewhat feeling of cheaper quality if you compare it to Orb X but that is quite reasonable considering the chair itself is around 3.5 times cheaper than Orb X which really puts it in range of everyone can get it. But does a much cheaper price means low quality? Let’s explore.

IW Unicorn

IW unicornThe 2021 CLUVENS BRAND newly issued model UNICORN has fully electrical tilting capabilities to 160 degrees, Reading light-two LED & RGB illumination lighting, manual open/close keyboard tray, and armrests. This model is suitable for home and office, and also gaming computer work environments. It offers functions that enable the user to experience unprecedented comfort and quasi total immersion through strategically positioned 1-3 monitors, audio systems, and accessories. The result is a complete computer office, ergonomically optimized, with a minimal footprint that improves overall performance and productivity and health and comfort. Sitting on a chair can help a lot for relieving health problems like lower back pain, herniated discs, sciatica, and neck pain and also enhance performance and viewing effects.

More Luxury and More comfortable:

Equipped with Luxury feeling reclining Gaming chair made with high-density Mold Shaping Foam and superior quality PU leather with very comfortable texture, electrical recline to 128 degrees, and more to 160 degrees for the flat position for the user.

More High-End Setting and more High-tech:

Manual push for open / close of big sized (87x34cm) Self-Balancing Keyboard tray, adjustable with 20cm distance range with Electrical control for the height of roof arm & monitors. Electrical control for reclining Zero Gravity position or even flat position, Manual adjusted Feet pedal for a more comfortable position for feet. Using a High-Quality PU leather Gaming chair that has Heat/Massage functions with it! The IW-Unicorn monitor mounts allow the use of a single monitor up to Ultra-wide 49” or 43” in size or triple monitor setups up to 3 x 29” other monitors configurations are available upon request. (VESA standard)

IW Scorpion

IW scorpionScorpion is basically a premium version of Unicorn with being able to hold more weight, having cup holders on the armrest, etc. The look is also similar with Scorpion being more sinister-looking but overall Steel frame and chair are the same.

Conclusion

Sadly I have not personally experienced neither of these products including Orb X but from all information I have found and looked over, I would say these products are not trying to compete with each other. Although Products are similar in nature, Orb X is aimed at hi end-users focusing on privacy and robustness while IW is filling the gap of users that would like an advanced chair but are not willing or ready to shell hi amount of money for it offering advanced chairs with advanced features in somewhat affordable price.

Diablo 2 Resurrected facing server issues
It has been some time since the release of Diablo 2 resurrected and overall reception was pretty good. People are enjoying the old classic game in hi-def. resolution and with new and improved visuals. Sadly some server issues are present still until this day and somewhat spoil the experience for players. diablo 2 server statusThe greatest lag and server crashes are pinpointed to game-creating events. When a player creates a new online game, the server needs to pull a lot of details from the database and make a game, due to some legacy code present this process takes some time and it is demanding a bit on the server-side, and although code was optimized to cater to more modern approach some legacy code still remains. Another thing that was spotted to affect performance itself is player behavior, to be more specific, modern gamer behavior. Where players find good builds and runs on the internet and then go to farm-specific areas or bosses for loot or experience points, which in return boils down to making plenty and short runs that are made by creating games and after run eliminating them. Now pair that with the previous statement about legacy server and database code and you can add 1 and 1 and see how this might be an issue. A lot of short games over legacy code are placing games in a state it was not designed for back in 2001 and therefore we have issues. Sadly solutions without completely rewriting the whole code are not very promising and they include rate limiting, which will prevent players to create many games in succession in a short period of time and maybe even login queues to drop a load on servers. Blizzard reached to people in the whole company, even old diablo 2 developers to ask for advice and they say that they are working on solutions so they could lift limitations and have everything running fine.

How to get rid of Chedot

Chedot is a Chromium-based Browser that replaces your default System Internet Browser. This browser offers users tools for downloading videos, faster browsing, and custom searches. From the publisher: A feature of our browser is a high speed on slow computers, high speed download on a poor internet, support resuming file download when connection is broken and the download in multiple threads, the ability to go on blocked websites and downloading videos from video sites.

While this may seem interesting and good at start, this browser has been marked as a Potentially Unwanted Program. It monitors user activity, collects web traffic data, and user information. While using Chedot you may see additional ads throughout your browsing sessions.

About Potentially Unwanted Applications

Exactly what is a Potentially Unwanted Program (PUP)?

People have encountered it – you download a free software, you then discover some unwanted applications on your computer system or discover a strange toolbar has been included with your browser. You didn’t have them installed, so how did they appear? These unwanted applications, which are called Potentially Unwanted Programs, or PUP in short, usually tag along as a software bundle when downloading the application and could cause serious problems for computer users. PUP does not involve malware in the traditional sense. What normally makes a PUP different from malicious software is the fact that when you download one, you’re doing it with your consent – although in most cases unintentionally and reluctantly. But, there is no doubt that PUPs remain bad news for computer users as it can be incredibly damaging to the PC in many ways.

How do unwanted programs affect you?

Unwanted programs come in many forms. More commonly, they will be found in adware bundlers which are known to utilize aggressive and misleading advertising. The majority of bundlers install many adware applications from a number of vendors, each of which features its own EULA policy. Safebytes Anti-malware completely removes this threat and safeguards your PC against PUP or malware infection. PUPS also appear in the form of undesirable toolbars or internet browser plug-ins. Not just they needlessly use up space on your screen, toolbars can also manipulate search results, track your web browsing activities, decrease your internet browser’s performance, and slow down your web connection to a crawl. They could seem harmless but PUPs are generally spyware. They may include dialers, keyloggers, and also other software built inside them that could monitor you or send out your sensitive information to 3rd parties. Because of this unwanted program, your application may freeze, your security protections can get disabled that could leave your computer susceptible, your system could get ruined, and this list goes on and on.

Tips for preventing PUPs

• Study cautiously prior to agreeing to the license agreement as it could have a clause about PUPs. • Always opt for the custom if you are given an option between Recommended and Custom Installations – never click Next, Next, Next thoughtlessly. • Install an advert blocker/pop-up blocker; Deploy anti-malware products such as Safebytes Anti-malware. These software programs will establish a wall between the computer and online criminals. • Be alert when you download and install freeware, open-source software, or shareware. Avoid downloading and installing browser extensions and applications you are not knowledgeable about. • Always download software from reliable sources like official sites as opposed to untrustworthy sharing space. Avoid torrents and peer-to-peer clients.

What To Do If You Cannot Download Safebytes Anti-Malware?

All malware is bad, but certain types of malware do much more damage to your PC than others. Some malware sits in between your computer and the net connection and blocks some or all internet sites that you really want to check out. It will also block you from installing anything on your PC, especially anti-malware applications. So what to do when malicious software keeps you from downloading or installing Safebytes Anti-Malware? Although this type of issue will be tougher to get around, there are some actions you can take.

Install the antivirus in Safe Mode

In Safe Mode, you can adjust Windows settings, un-install or install some software, and get rid of hard-to-delete viruses. In the event the virus is set to load immediately when PC 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 the F8 key while the PC is booting up or run MSConfig and look for the “Safe Boot” options under the “Boot” tab. Once you’re in Safe Mode, you can try to install your antivirus program without the hindrance of the virus. Now, you can run the anti-malware scan to eliminate computer viruses and malware without any hindrance from another malicious application.

Download the antivirus software using a different browser

Some viruses might target vulnerabilities of a specific browser that block the downloading process. If you suspect that your Internet Explorer happens to be hijacked by a virus or otherwise compromised by cybercriminals, the best approach is to switch over to an alternate web browser like Chrome, Firefox, or Safari to download your chosen security software – Safebytes Anti-Malware.

Make a bootable USB anti-virus drive

Here’s another solution which is creating a portable USB anti-virus software that can scan your system for malware without the need for installation. Follow these steps to run the anti-virus on the affected PC. 1) Download Safebytes Anti-Malware or Windows Defender Offline onto a clean computer. 2) Plug the USB drive into the uninfected PC. 3) Double-click on the downloaded file to open the installation wizard. 4) Choose the drive letter of the flash drive as the place when the wizard asks you exactly where you would like to install the anti-virus. Follow the on-screen instructions to complete the installation process. 5) Now, transfer the pen drive to the infected PC. 6) Double-click the EXE file to run the Safebytes tool from the flash drive. 7) Press the “Scan Now” button to start the virus scan.

Copy and Paste feature is not working
One of the most basic and commonly used features in the Windows operating system is the copy and paste feature that helps users accomplish tasks in a faster and easier way. However, if you notice that it’s not working properly for some reason, then this post might be of help as it will provide you with options you can check out to resolve the problem. You can encounter this kind of problem with the copy and paste feature if some system files are corrupted or if there’s some third-party application or process that interferes with this function. Worry not though for there are some options you can check out to fix this. You can try to restart the rdpclip.exe process or the explorer.exe process. You could also try to reinstall the program where you encountered the issue with the Copy and Paste function. In addition, you could try clearing the clipboard history or run the built-in tools like the DISM tool and SFC scan. You could also troubleshoot the problem in a Clean Boot State or use the Refresh Windows tool. For more information, refer to each one of the options below.

Option 1 – Try to restart the rdpclip.exe and the explorer.exe processes

The first thing you can do to resolve the problem is to restart certain processes namely, the rdpclip.exe process and the explorer.exe process via Task Manager.
  • First, right-click on your Taskbar and select the Task Manager.
  • Next, look for the rdpclip.exe process and right-click on it, and select the End process option.
  • After that, click on the File tab > Run new task and then type “rdpclip.exe” and tap Enter.
  • This should help fix the problem. If not, you could also try to restart the explorer.exe process – just look for the explorer.exe process in the Task Manager and right-click on it, and then select the Restart option.

Option 2 – Try reinstalling the concerned program

If you only experience this issue on a particular program, you might want to uninstall this program and install it back again, and then see if it fixed the problem or not.

Option 3 – Try to clear the clipboard history

You could also try clearing the clipboard history as it has been known to help in fixing this kind of issue. You can clear the clipboard history using the command line.

  • 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.)
  • Now try to connect your device or copy the files to your external device again and check if the problem with the Copy and Paste function is fixed.

Server certificate revoked ERR_CERT_REVOKED!
While browsing the internet, if you suddenly encounter a warning with an error message saying, “Server certificate has been revoked ERR CERT REVOKED” then it indicates that the SSL certificate used by the website has been revoked by its issuer. This kind of problem can only be fixed by the website owner but that does not mean that you can’t do anything about it. In fact, you have the option to bypass this error as well as contact the certificate issuer – all this and more. Just a reminder, if a website that accepts payment, its passwords don’t have SSL or has some certification issue, you should never trust it. For instance, if you are trying to purchase something online and you’re on the payment stage but you encounter the “Server certificate has been revoked ERR CERT REVOKED” error, you must not proceed. To resolve the “Server certificate has been revoked ERR CERT REVOKED” error, here are some things you can do.

Option 1 – Try contacting the Certificate Issuer

If you are the website owner, of course, the best thing you can is to get in touch with the Certificate Issuer in order to resolve the problem.

Option 2 – Try fixing the Date and Time

You have to check your computer’s Date and Time. There are cases when this simple setting causes a connection problem. So if your computer Date and Time is set to date or time that this after the certificate expiration date, then you have to make sure that you set it to automatically configure time. To do so, just open Settings > Time and Language. From there, turn on the toggle for “Set time automatically” and “Set time zone automatically” options. After that, check if it fixes the error, if not, you need to check if the manual selection is correctly set or not.

As pointed out earlier, you have the option to bypass the Certificate Revocation check. All you have to do is follow the steps below.
  • In the search box of your browser, type “internet options” and open it once it appears.
  • After that, go to the Advanced tab and navigate to the Security subheading.
  • Next, uncheck the “Check for publisher’s certificate revocation” option as well as the “Check for server certificate revocation” option.
  • Now restart your computer. Upon the next startup, try opening the website again. This time, your browser will stop checking it for certificate issues. However, it’s not safe to leave those options unchecked so make sure that once the website’s SSL certificate is fixed or once you no longer have to visit that website, you recheck those options.

  • Tap Win + R to launch Run.
  • Type in cmd in the field and tap Enter.
  • After opening Command Prompt, type in sfc /scannow

You might want to try logging into a different User Account since it is possible that the issue could have something to do with your log-in account. Thus, you can isolate this possibility by logging into a different user account. If you don’t have any other user account, simply create a new one by clicking on the Start icon and then go to Settings > Account > Family & other users. From there, go to the Other user's section and click on the Add someone else to this PC option, and then inputs all the needed information and restarts your computer. Once your computer has restarted, log into your computer using the newly created user account.

If the first three given options didn’t work, you might want to reset or reinstall the Calculator app. To do that, follow these steps:
  • Click on the Start button and go to Settings > Apps > Apps and features.
  • Next, look for the Calculator app from the app list and click on it to see its other options.
