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 AnytimeAstrology

AnytimeAstrology is a browser extension for Google Chrome developed by Mindspark Inc. When installed, this extension will change your default new tab page to a custom search provider called MyWay (search.myway.com).

While browsing the internet with this extension installed, you will see additional ads through your browsing sessions, including but not limited to Sponsored Content, Injected Ads and Pop-up Ads.

While AnytimeAstrology is active it will monitor your browsing habits, recording website visits, clicked links, viewed products, etc. This information is later sent back to Mindspark Ad network servers where it is used to better target additional injected ads into your web pages.

Several anti-virus applications have marked this extension as a Browser Hijacker and it is recommended to remove it from your computer.

About Browser Hijackers

Browser hijackers (also known as hijackware) are a kind of malicious software that modifies web browser configuration settings without the computer owner’s knowledge or approval. These hijacks are raising at an alarming rate globally, and it can be actually nefarious and often harmful too. Browser hijackers could do more than just changing homepages. In most cases, hijackers are created for the benefit of online hackers usually through income generation that comes from forced ad clicks and site visits. While it might seem harmless, these tools are made by malicious people who always try to take advantage of you, so that they can earn money from your naive and distraction. Browser hijackers can also permit other vicious programs without your knowledge to further damage your computer.

Key symptoms that your browser has been hijacked

The following are some symptoms that indicate you’ve been hijacked: 1. your homepage has been reset to some unfamiliar site 2. your browser is constantly being redirected to porn sites 3. default internet search engine is modified 4. you find unwanted new toolbars added 5. you observe a lot of pop-up ads on your screen 6. your browser has become unstable or starts running slowly 7. you can’t visit certain websites such as homepages of antivirus software.

How browser hijacker finds its way to your computer

Browser hijackers could use drive-by downloads or file-sharing websites or perhaps an e-mail attachment in order to reach a targeted computer. They could also come from add-on software, also referred to as browser helper objects (BHO), web browser extensions or toolbars. Browser hijackers sneak into your computer along with free software downloads that you unwittingly install along with the original. An example of some well known browser hijacker includes Conduit, Anyprotect, Babylon, SweetPage, DefaultTab, RocketTab, and Delta Search, but the names are constantly changing. The existence of any browser hijacker on your computer might considerably diminish the web browsing experience, monitor your internet activities that result in serious privacy issues, produce system stability issues and ultimately cause your PC to slowdown or to an almost unusable condition.

The best ways to remove a browser hijacker

Some hijackers can be simply removed by deleting the free software they came with or by eliminating any extension you have recently added to your system. The sad thing is, the majority of the software applications used to hijack a internet browser are deliberately built to be hard to eliminate or detect. Novice computer users should never attempt for the manual form of removal methods, since it calls for thorough computer knowledge to carry out repairs on the computer registry and HOSTS file. Installing and running anti-malware application on the affected system will automatically erase browser hijackers and other unwanted applications. SafeBytes Anti-Malware could counter persistent hijackers and give you proactive computer protection against all kinds of malware. Together with the anti-virus tool, a system optimizer, such as SafeBytes’s Total System Care, could help you in removing all linked files and modifications in the registry automatically.

How to Get rid of Malware that is Blocking Websites or Preventing Downloads

How to Fix Installation Error 1628

What Is Installation Error 1628?

Installation Error 1628 is, as the name suggests, an installation error. When it occurs, a generic 1628 message is displayed to the user. When this message appears, it is either a problem with the install files or an issue with the InstallShield.

Solution

Restoro box imageError Causes

Installation Error 1628 is caused because every Windows-based program or application has been designed that such that it has to be installed on the computer for use. This installation process is important because it not only moves files to the appropriate location on one’s hard drive but also because the process creates registry entries in Windows System files. A vast majority of these programs and applications have a built-in tool that’s responsible for aptly performing this installation. This built-in tool is the InstallShield. This establishes that when this error occurs, it is either because of some unforeseen issue that occurred during the installation process or because of some problem with the InstallShield.

Further Information and Manual Repair

In order to keep this error from occurring in the future, some recommendations are outlined below.
  • Check the installation disc and determine if there are any smudges, scratches, or fingerprints on it. If the system is unable to read data from the disc, Installation Error 1628 will be generated. In order to ensure that the Installation Disc is clean, use a microfiber cloth. Dampen it lightly with water and clean the disc. Wipe the inside of the disc lightly in an outward direction, making sure that it is not wiped in a circular pattern. Try to reinstall the application or program after cleaning the disc. The issue should be resolved. However, if it persists, some problems may be with the InstallShield.
  • The alternative solution is to repair the InstallShield and the procedure goes as follows.
  1. Stop InstallShield’s running process. It may have been crashed and simply needs to be restarted. Now access task manager. Press Ctrl+Alt+Del and the task manager will open. Now go to the processes tab and disable ‘idriver.exe’ and ‘msiexec.exe’ from here.
  2. Now go to ‘C: Program Files/Common Files’. Here you will find the ‘InstallShield’ folder. Select ‘rename’ and modify the folder name to ‘InstallShield1’. Confirm rename and start the installation process again. Now Windows will try to re-install any InstallShield files one needs.
  3. If the error persists after renaming the InstallShield folder, download the Windows Installer from Microsoft’s website. This file will determine whether or not your version is valid. Old versions often have bugs that cause problems. Your system is now ready to be used.

FreeDownloadManager Removal Tutorial

Free Download Manager is a software program developed by FreeDownloadManager.ORG. According to the publisher:

This software downloads files and converts videos. Its features include integration with all browsers, support of downloads from RapidShare, BitTorrent support, adjusting traffic usage, resuming broken downloads, and adds BitTorrent support, flash video download, upload manager, portable mode, and remote control.

During setup, the program creates a startup registration point in Windows in order to automatically start when any user boots the PC. It adds a browser extension to help it cache files you are downloading over your browser. The software is designed to connect to the internet and adds a Windows Firewall exception in order to do so without being interfered with. It also hooks up to start automatically and cache every download even if it's turned off.

This software comes bundled with video converters that some anti-virus programs marked as malware and therefore it is considered a potentially unwanted program.

About Potentially Unwanted Applications

If you’ve ever downloaded freeware or shareware, odds are high that your computer can get installed with a bunch of unwanted programs. These unwanted applications, officially known as Potentially Unwanted Programs (PUPs), often come bundled with other software and install themselves on user’s computers without their knowledge. They might not look like computer viruses to some individuals, but they can create huge annoyances and lead to serious difficulties for users. It’s clear by its name – unwanted programs – but did not really constitute “malware” in the traditional sense. What makes a PUP different from malware is the fact that when you download one, you’re doing it with your approval – even though in most cases unconsciously and unwillingly. Nevertheless, there is no doubt that PUPs continue to be bad news for PC users as they can be incredibly detrimental to your computer in several ways.

How does unwanted software affect you?

Unwanted programs come in various forms. Usually, they could be found in adware bundlers that are known to use aggressive and deceptive advertising. The majority of bundlers install multiple adware applications from a number of companies, each of which has its own EULA policy. Safebytes Anti-Malware entirely eliminates this threat and safeguards your PC against PUP or adware infection. They will also come in the form of web browser extension add-ons and toolbars. Not just they needlessly fill up space on your computer screen, toolbars could also manipulate search results, keep an eye on your web browsing activities, decrease your internet browser’s efficiency, and slow down your net connection to a crawl. Potentially unwanted programs utilize aggressive distribution methods to get in your computer. They will often include things like information gathering code that will collect and send your private information to other companies. Due to this unwanted program, your application may freeze, your security protections may get turned off that can leave your computer susceptible, your system could get damaged, and this list goes on and on.

Tips to prevent PUPs

• Always read the license agreement and privacy statement. Don’t agree unless you understand exactly what you are acknowledging. • Always choose “Custom” or “Advanced” installation and don’t blindly click the Next button, which will allow you to uncheck any foistware software programs you do not want. • Install an ad blocker/pop-up blocker; Add anti-malware products such as Safebytes Anti-Malware. These applications could establish a wall between the computer and cybercriminals. • Be alert if you install freeware, open-source programs, or shareware. Nowadays ‘freeware’ is not really freeware – but ‘crapware’ bundling nonsense. • Always download software from trusted sources like official websites instead of untrustworthy sharing space. Avoid file-hosting sites wherever possible.

What driver to use inside Windows
When clean Windows is installed or when you place new hardware in your computer usually Windows itself detects the device and installs its driver. The question that comes now is, do you keep that driver or do you install the manufacturer's one. In order to answer this question let's analyze what is difference between the two drivers and other factors which could influence your decision.

Difference between drivers

First of all, know that drivers Windows installs are also drivers from the device manufacturer which have gone through Microsoft quality control in order to be included in Windows itself. Now naturally question which occurs, what is the difference, well answer to that would be this: in Windows, you have stripped down driver, just a driver in order for Windows to know what device is plugged and how to use it, meaning that for example if you install printer device, you will be able to print documents and Windows will know it is a printer but ... You will not get the control panel for that printer where you can adjust the printer itself and all of its features like let's say paperweight, etc. So if you need these kinds of features in that case it would be better to install a complete driver suite from the manufacturer and get the whole package. Windows will recognize the RAZER mouse for example but you will not be able to change its colors of program custom buttons on it until you install RAZER drivers. One more important thing to note is that drivers which are in Windows are less updated than drivers from the manufacturer's site. That being said, if you prefer and want to have the latest drivers you will prefer to get them again from the manufacturer.

Conclusion

So it seems that manufacturer's drivers are always in some form of advantage and that you will always want them and most of the time this is true, as a matter of fact, the only time I could think that you could use bare down Windows drivers is when new drivers update breaks something in Windows and device start behaving improperly. in this particular case, it is better to roll back to the previous Windows driver which has passed Microsoft quality control and is working for sure. In any other case, you are better off with the latest manufacturers drivers If you would like to read more helpful articles and tips about various software and hardware visit errortools.com daily.

Change system font in Windows 10
In previous versions of Windows changing the system, the font was a pretty straightforward process, but it seems Microsoft did not want this feature to keep for whatever reason and there is no option as of the time of the writing of this article to do it in standard options in Windows 10. But do not worry, you are still able to customize your Windows and choose which font would you like to see inside it in all of its dialogs. You can choose whichever font you desire, the only prerequisite is it to be installed on your system. This guide will require you to change values in the registry of Windows itself so please follow step-by-step instructions and always make a backup of the registry before changing it in order to prevent some permanent Windows issues. All of that being said, let's start.

Setting new font

First thing is to open notepad, in the notepad paste the next block of code:
Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts] "Segoe UI (TrueType)"="" "Segoe UI Bold (TrueType)"="" "Segoe UI Bold Italic (TrueType)"="" "Segoe UI Italic (TrueType)"="" "Segoe UI Light (TrueType)"="" "Segoe UI Semibold (TrueType)"="" "Segoe UI Symbol (TrueType)"="" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes] "Segoe UI"="NEW_FONT"
Where in "Segoe UI"="NEW_FONT" instead of NEW_FONT you need to write the exact name of the font that you wish to use as a system font. Once you have replaced the default system font with your desired one, go to File and save as, from file type drop-down menu, choose all files and save this file as .REG type giving it whatever name you wish. When the file is saved, close notepad, right-click on the saved file and choose the merge option. Confirm with YES and click on OK. Reboot your system and your Windows will now use the font of your choice as its default system font.

Restoring default font

If you wish to return the old default system font as it was, follow the same steps but in your notepad paste this code:
Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts] "Segoe UI (TrueType)"="segoeui.ttf" "Segoe UI Black (TrueType)"="seguibl.ttf" "Segoe UI Black Italic (TrueType)"="seguibli.ttf" "Segoe UI Bold (TrueType)"="segoeuib.ttf" "Segoe UI Bold Italic (TrueType)"="segoeuiz.ttf" "Segoe UI Emoji (TrueType)"="seguiemj.ttf" "Segoe UI Historic (TrueType)"="seguihis.ttf" "Segoe UI Italic (TrueType)"="segoeuii.ttf" "Segoe UI Light (TrueType)"="segoeuil.ttf" "Segoe UI Light Italic (TrueType)"="seguili.ttf" "Segoe UI Semibold (TrueType)"="seguisb.ttf" "Segoe UI Semibold Italic (TrueType)"="seguisbi.ttf" "Segoe UI Semilight (TrueType)"="segoeuisl.ttf" "Segoe UI Semilight Italic (TrueType)"="seguisli.ttf" "Segoe UI Symbol (TrueType)"="seguisym.ttf" "Segoe MDL2 Assets (TrueType)"="segmdl2.ttf" "Segoe Print (TrueType)"="segoepr.ttf" "Segoe Print Bold (TrueType)"="segoeprb.ttf" "Segoe Script (TrueType)"="segoesc.ttf" "Segoe Script Bold (TrueType)"="segoescb.ttf" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes] "Segoe UI"=-
Reboot your system and your Windows will now revert the font of your choice as its default system font.
