What are the most dangerous computer viruses?
There isn’t a definitive answer to this question as it largely depends on opinion. However, there are some computer viruses that are considered to be more dangerous than others.Below is a list of some of the most dangerous computer viruses in existence:
1. ILOVEYOU
This virus was first released in 2000 and quickly spread throughout the world, infecting millions of computers. The ILOVEYOU virus was so destructive because it hid itself within email attachments and once opened, would replicate itself and send itself out to everyone in the victim’s address book. This virus caused an estimated $5.5 billion in damages.
2. Code Red
Code Red was a worm that exploited a vulnerability in Microsoft’s IIS web server software. It was released in 2001 and quickly spread, infecting over 359,000 systems in just nine days. The worm would deface websites with a message that read “Hacked by Chinese!” and also caused significant Denial of Service attacks. Code Red was eventually neutralized by a tool created by eEye Digital Security.
3. Nimda
Nimda was released in 2001, just a month after the Code Red worm. It was estimated to have infected over six million systems in just 24 hours. Nimda used multiple methods of infection, making it hard to defend against. It could spread via email attachments, network shares, and even by infecting HTML web pages. The Nimda worm also had the ability to replicate itself and createBackdoors, making it a dangerous and destructive malware.
4. Sasser
Sasser was a worm that exploited a buffer overflow vulnerability in the Windows Local Security Authority Subsystem Service (LSASS). It was released in 2004 and quickly spread, infecting over 50,000 systems in just a few days.The Sasser worm would cause infected computers to crash and then automatically reboot. This made it difficult for users to work with their computers and also caused extensive damage to networks. Sasser was eventually neutralized by a tool created by F-Secure.
5. Mydoom
Mydoom was a worm that was released in 2004 and is considered to be the fastest spreading email worm of all time. It was estimated to have infected over 1 million systems within the first 24 hours of its release. Mydoom used emails to spread itself and also included a backdoor, giving attackers remote access to infected computers. This worm caused significant damage to networks and also resulted in Denial of Service attacks against major websites like Google and SCO. Mydoom was eventually neutralized by a tool created by Symantec.
6. Conficker
Conficker is a worm that was released in 2008 and is still active today. It uses a variety of methods to spread, including network shares and infected USB drives. Once a computer is infected, Conficker can disable security features and block access to websites that provide security updates. It can also download and execute malicious files, making it a dangerous threat. Conficker has infected millions of computers and is considered to be one of the most sophisticated malware ever created.
7. Stuxnet
Stuxnet is a computer worm that was discovered in 2010. It is believed to have been created by the United States and Israel in order to sabotage Iran’s nuclear program. Stuxnet specifically targets industrial control systems and can cause physical damage to equipment. It is considered to be one of the most sophisticated malware ever created and has caused significant damage to Iran’s nuclear program.
While there are many other computer viruses that could be considered dangerous, the ones listed above are some of the most destructive and feared.
What are the most dangerous computer viruses?
in 2014
The most dangerous computer virus is the one that is currently wreaking the most havoc. By that metric, the most dangerous virus in 2014 was Cryptolocker, a ransomware virus that first surfaced in September of 2013. Cryptolocker encrypts victims’ files using AES-256 encryption, then demands a ransom of 2 Bitcoins (approximately $1,000 at the time of this writing) to decrypt the files.
While many ransomware viruses pop up and then quickly fade away, Cryptolocker has proven to be incredibly resilient. It has been spreading rapidly via email attachments and infected websites, and has been successful in extorting ransom payments from a large number of victims. Additionally, a recent report from Dell SecureWorks’ Counter Threat Unit found that the Cryptolocker gang has collected over $3 million in ransom payments since the virus first surfaced.
The best way to protect yourself from Cryptolocker (or any other ransomware virus) is to maintain good backups of your important files. That way, even if your files do get encrypted, you can restore them from your backups and won’t need to pay the ransom. You should also avoid opening email attachments from unknown senders, and be careful when browsing the web – if you do end up on an infected website, you could end up inadvertently infecting your computer.

Most people know about computer viruses because they have heard about them in the news or from friends. However, few people know about the most sophisticated and dangerous computer virus. This virus is known as Stuxnet.
Stuxnet was first discovered in 2010 by security experts. It is a computer worm that targets industrial control systems. These are the systems that are used to control things like nuclear power plants and water treatment facilities.
Stuxnet was designed to cause physical damage to these types of facilities. It does this by taking over the control systems and then making changes to the settings. This can cause the machines to break or to operate in a unsafe manner. For example, Stuxnet caused some centrifuges at an Iranian nuclear facility to spin out of control and break.
Stuxnet is so sophisticated that it is believed to have been created by a nation state. It is believed that the United States and Israel created Stuxnet together. They created it in order to damage the Iranian nuclear program.
Stuxnet is a very serious threat because it can cause physical damage to critical infrastructure. It is also difficult to detect and remove. For these reasons, it is important to take steps to protect yourself from Stuxnet and other computer viruses.
There are a few things you can do to protect yourself from computer viruses like Stuxnet. First, you should install a good antivirus program on your computer. This will help to detect and remove viruses. You should also be careful about the websites you visit and the emails you open. Don’t click on links or open attachments from people you don’t know. Finally, you should keep your computer up-to-date with the latest security patches.
