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.

10 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 they get into your PC

Browser hijackers may use drive-by downloads or file-sharing networks or perhaps an e-mail attachment in order to reach a targeted computer. Many browser hijackings originate from add-on applications, i.e., toolbars, browser helper objects (BHO), or extensions added to web browsers to provide them additional functionality. A browser hijacker may also come bundled up with some freeware that you inadvertently download to your computer, compromising your internet security. A good example of some notorious browser hijackers includes Anyprotect, Conduit, Babylon, SweetPage, DefaultTab, Delta Search, and RocketTab, but the names are constantly changing. Browser hijacking can bring about severe privacy issues and even identity theft, disrupt your browsing experience by taking control over outbound traffic, considerably slows down your computer by depleting lots of resources and result in system instability also.

How to repair a browser hijack

Certain hijackers can be removed by simply uninstalling the corresponding free software or add-ons from the Add or Remove Programs in the Microsoft Windows control panel. Yet, some hijackers are far harder to find or get rid of as they might get themselves connected with some critical system files which allow it to operate as a necessary operating-system process.

Steam proton to run Windows games on Linux

Despite popular belief, there are a lot of users running Linux OS. Linux offers great security and working environment and 96.3% of the world's top 1 million servers run on Linux. 90% of all cloud infrastructure operates on Linux and practically all the best cloud hosts use it. But gaming on Linux is limited, enter Steam proton a Valve’s gaming solution.

What is Steam proton?

Proton is a WINE fork with some extra capabilities, to play games and run applications not native and not made to run natively under Linux OS. It is supposed to bridge the Gaming issues for PC users and let them more freedom in choosing an operating system to game on.

Find out if your game supports Proton

Although there are a lot of titles that nowadays run natively on Linux some will still need proton in order to run at all and sadly some of them will not be able to run on Linux even via proton but seeing how Valve is busy and it is trying to push its ideas and technology slowly this gap is closing. In order to see how the game you want to play performs and behaves on Linux and proton environment visit https://www.protondb.com/ and find out. As soon as the site loads you will be greeted with statistics and a search option to find out the status of the desired game with one of the given statuses: Borked, Bronze, Silver, Gold, Platinum, and Native. As you probably guessed native means that the game will work on Linux out of the box and borked will probably not work at all. Platinum and gold status means that game will run on proton without any input or tweaks from the user while silver and bronze means that it will work but might need some tweaks in order to make it work.

How to get Steam proton?

In order to run games under proton inside Linux, you will need firstly a Steam client which luckily works naturally on Linux. Unlocking/activating Steam Proton on your Linux-based system is easy. Just head over to Steam > Settings > Steam Play and toggle the option “Enable Steam Play for Supported Titles”. Valve has tested and fixed some Steam titles and you will now be able to play those titles. However, if you wish to go even further beyond, and play titles that even Valve has not tested, toggle the option “Enable Steam Play for all titles”.

Conclusion

Even we are not there yet, native gaming on Linux is gaining a foothold each day. Will Steam’s OS with proton technology be one that will turn the tide from Windows or some other tech we cannot tell but one thing is for sure, more choices mean better products so I am hopeful for a bright future.

Identify resource hogging applications

Resource hogging is a term when one single application or few of them are taking all system resources for themself causing extreme slow down in the computer and nonresponsiveness. It can be a very frustrating and time-consuming experience and it can cost you money if you can not finish work on time due to this effect. I believe that everyone has experienced at least one slowdown in their IT carrier because of resource-hogging applications and most users do not know how to deal with this. We are here to help you with this issue. Just to be aware that this method shown here is not a method to miraculously speed up your PC or anything similar, this is to be able to detect and recover from extreme slowdowns. Hardware components are still very important and if you can upgrade your computer if it is outdated, please do it because new applications will require a more modern system, and not any kind of tips and tricks will save you from outdated hardware.

Identifying resource hogging app

Now when we got that out of the way let's talk about slowdowns, it is no secret that sometimes an application has bugs and memory leaks that can cause this kind of behavior, and sometimes the application simply takes up too much memory for any other application to work normally. The most simple and straightforward way is to bring up a Windows task manager and inspect running applications and services. You can bring task manager by the key combination of CTRL + SHIFT + ESC If the system is in deep memory deficit you will have to wait for the task manager to open and show itself on-screen. Once opened, click on more details if that view is not opened by default. Once the view expands you will see all running applications with how much RAM memory have they taken and how much CPU they are using.

What to do with app?

Downloads folder loads slowly in Windows

If you are frequently experiencing slow loading of folders in your Windows 10 computer, Downloads folder for instance, then you’ve come to the right place as this post will help you resolve such issue. Slow loading of folders is a common problem faced by many users even when they are using the latest hardware like SSDs. So if you experience the same thing, be it with the Downloads folder or other folders on your computer, there is a way to resolve that issue and make the folder load faster. Slow-loading means when you attempt to open the folder, it takes a couple of seconds before it displays its contents. In such cases, you’ll see a green loading address bar that says “Working on it” which can get quite annoying especially if you are in a hurry. And if you notice that this only happens in the Downloads folder, there certainly is something wrong. This kind of problem can occur on SSDs and normal hard drives. The main reason behind the occurrence of this problem is that the folder may have been optimized for viewing photos or other media formats which is why it takes quite longer than usual to load all the files and their thumbnails. However, since the Downloads folder usually contains all kinds of files like documents, zip files, audio/video files, etc. there is no need to optimize this folder for media files only because doing so is only going to make the Windows File Explorer slow in loading the folder’s contents and thumbnails which does not exist for many files.

Option 1 – Configure the Downloads folder

Right-click on the Downloads folder or the folder you’re having trouble opening.
Then click on Properties and go to the Customize tab.
After that, click on the “Optimize this folder for” option in the drop-down menu.
Next, select General items from the drop-down which might have been set by default to Pictures or Video.
You also have the option to apply this template to all the subfolders, that is if your folder has any subfolders.
Now apply the settings and restart Windows Explorer.

Note: Once you’ve completed the steps above, it should now make the folder content display a lot faster than before. Now try to open the Downloads folder which would not take much time as you will see the changes right away.

Option 2 – Run CHKDSK to check your disk for errors

When it comes to some issues concerning the hard drive or removable devices, there is a utility in Windows that might help which is called “chkdsk”. This error check utility can help with several issues in the system including File System Error -2147219196.

Tap the Win + S keys to open the Search box.
Then type “command prompt” in the field and from the search results that appear, right-click on Command Prompt and select “Run as administrator”.
After opening an elevated command prompt, copy and paste the following command and hit Enter:

chkdsk /r /f

Now if you are prompted to run CHKDSK after your reboot your PC, just tap Y and reboot your PC.
If CHKDSK is not able to find any errors, tap the Win + E keys and navigate the access window. From there, right-click on the concerned drive and click on Properties.
After opening Properties, click on the tab Tools and then click on the “Check” button under the Error-checking section.
Wait until the process is completed and then restart your computer.
Once your computer has restarted, try accessing the file and check if the error persists.

Cleaning your PC for better performance

Hello everyone, last time we were talking about disk cleanup and its benefits, but as you need to keep your System clean you should also clean and keep your hardware clean as well. Many system issues could be traced and could happen due to dirty PC. In this article, we will give you tips on how to perform safely cleaning on your computer and hopefully point good sides to it so you can develop a healthy habit of regularly cleaning it and keeping it tidy. dirty PC that needs cleaning

Keeping your PC clean is not rocket science and you can do it with things you already and probably have in your house. One thing that I would recommend tho to purchase is antistatic gloves since they could prevent any kind of electrostatic discharges thus protecting your electric components. If you have the option to disconnect your PC and get it outdoors, I would highly recommend this approach since all the dust will be dusted outside and not in the room where your computer is. If you can not it is still ok, but since some portion of dust will be set in the room, you might need to dust your room after cleaning your computer.

Cleaning outside case & redusting inside

The first thing after disconnecting your computer is to dust it from outside, here you will need a vacuum cleaner and a brush, gently brush outside dust from your casing and vacuum it with your vacuum cleaner. You can use dustcloth for larger parts but use the brush for fans and connectors. After you have done cleaning the outside part, open the side of your computer casing, put on your antistatic gloves, and get a fine and soft brush, repeat dusting and vacuuming of the inner parts of your computer. If your computer is not regularly been cleaned this part will take a little longer since there would be excess dust inside and it will take a longer time to vacuum it all but keep going until you are left with no dirt.

Cleaning it inside

Fans are troublesome to clean since they will rotate when brushed and that could make you miss certain sports, in order to battle this get a tape and stick the fan into one position, brush areas that you can reach, then unstick it, rotate the head, stick it again in another position and dust off remaining areas which you could not reach before. If your computer is very dirty and some hard dirt is at bottom of the connectors, disconnect desired component and clean the connection properly. plug it back in immediately after cleaning to avoid connecting it somewhere else. Harder stains that could not be dusted could be cleaned with little alcohol. Get your dustcloth just a little wet with alcohol, just a corner, and gently wipe out sticky dust or spills if they are present. Leave it 10 minutes for alcohol to evaporate before plugging it back into an electric socket.

Thermal paste and cable management

If you have money and expertise, every 2 years would be a good idea to change the thermal paste on your processor, all you need to do is buy it from your local computer store online, remove the CPU fan clean the CPU and bottom of the fan and apply new thermal paste, place fan back and lock it. If you do not have expertise in this area, call someone who has to show you how it is done. When cleaning it would be a good idea if you do not have any cable management to do it now, nice and tidy cables not only look good, they also improve your air circulation inside your casing making your computer cooling better. once you are done with it, close back the casing side and plug it back in the wall.

Peripherals

When you are cleaning your computer, do yourself a favor and clean your keyboard, mouse, and screen as well. the keyboard can be quickly cleaned with compressed air in the can and screen and mouse with dustcloth. That's it, remember, keep your PC clean and tidy and enjoy the benefits of non-hardware malfunctions caused by dirt and dust. cleaned PC
