What are the most dangerous computer viruses?
The most dangerous computer viruses are typically the ones that are the most difficult to detect and remove. Some of the most common and dangerous virus types include the following:
Trojan Horses: A Trojan horse is a type of virus that is disguised as a legitimate file or program. When you execute the file or program, the Trojan horse virus is activated and can do damage to your system, such as deleting files, stealing information, or corrupting data.
Worms: Worms are similar to Trojan horses in that they are also malicious programs that can damage your system. However, unlike Trojan horses, worms are able to replicate themselves and spread to other computers on a network. This can quickly cause extensive damage if not contained.
Spyware: Spyware is a type of virus that is designed to collect information about you without your knowledge. This information can be used for identity theft or other malicious purposes. Spyware can be difficult to remove, as it is often bundled with other legitimate programs.
Adware: Adware is a type of virus that displays annoying or intrusive advertisements on your computer. These ads can be in the form of pop-ups, banners, or even full-screen advertisements. Adware can be difficult to remove, as it is often bundled with other legitimate programs.
Ransomware: Ransomware is a type of virus that can encrypt your files or lock your computer so that you cannot access it. The attacker then demands a ransom be paid in order to decrypt your files or unlock your computer. This can be a very costly virus to deal with, as you may be forced to pay the ransom in order to regain access to your data.
These are just some of the most common and dangerous virus types that are out there. It is important to have a good antivirus program installed on your computer and to keep it up-to-date in order to protect yourself from these threats.

With over 60,000 new viruses popping up every year, it’s hard to keep track of which ones pose the biggest threat. Here is a list of the 10 most dangerous computer viruses of all time.
1. ILOVEYOU
Also known as the Love Bug, this virus wreaked havoc in 2000, infecting millions of computers and causing an estimated $5.5 billion in damages worldwide. The ILOVEYOU virus was spread via email attachments and once opened, would send itself to everyone in the victim’s address book. It would also overwrite any files it came into contact with, making them unrecoverable.
2. Code Red
Named after the popular soft drink, Code Red was a worm that attacked Microsoft IIS web servers in 2001. It would exploit a buffer overflow vulnerability in the server software to gain access and then create a back door, allowing remote access. Code Red was particularly dangerous because it was able to spread quickly and caused a large amount of damage, with an estimated $2 billion in damages worldwide.
3. Meliss
This virus, named after the Greek Goddess of bees, was one of the first viruses to target Mac computers. It was spread via email attachments and would infect the victim’s computer with a payload that would send itself to everyone in the victim’s address book. Once a computer was infected, it would become sluggish and unresponsive.
4. Sasser
Sasser was a worm that targeted Microsoft Windows computers in 2004. It would exploit a vulnerability in the Local Security Authority Subsystem Service (LSASS) to gain access and then allow remote access. Sasser was particularly dangerous because it caused a large amount of damage and was able to spread quickly.
5. Mydoom
Mydoom was a virus that spread via email attachments in 2004. It would infect the victim’s computer and then send itself to everyone in the victim’s address book. Once a computer was infected, it would become sluggish and unresponsive. Mydoom was particularly damaging because it caused a large amount of damage and was able to spread quickly.
6. SoBig
SoBig was a virus that spread via email attachments in 2003. It would infect the victim’s computer and then send itself to everyone in the victim’s address book. Once a computer was infected, it would become sluggish and unresponsive. SoBig was particularly damaging because it caused a large amount of damage and was able to spread quickly.
7. Storm
Storm was a worm that spread via email attachments in 2007. It would infect the victim’s computer and then send itself to everyone in the victim’s address book. Once a computer was infected, it would become sluggish and unresponsive. Storm was particularly damaging because it caused a large amount of damage and was able to spread quickly.
8. Conficker
Conficker was a worm that spread via network shares in 2008. It would infect the victim’s computer and then allow remote access. Conficker was particularly dangerous because it was able to spread quickly and caused a large amount of damage, with an estimated $9 billion in damages worldwide.
9. Stuxnet
Stuxnet was a worm that spread via USB drives in 2010. It would infect the victim’s computer and then allow remote access. Stuxnet was particularly dangerous because it was designed to target industrial control systems, such as those used in nuclear facilities.
10. WannaCry
WannaCry was a ransomware that spread via email attachments in 2017. It would encrypt the victim’s files and then demand a ransom to decrypt them. WannaCry was particularly damaging because it caused a large amount of damage and was able to spread quickly, with an estimated 150,000 computers being infected in just a few days.
These are just a few of the most dangerous computer viruses of all time. While there is no surefire way to protect your computer from viruses, you can reduce your risk by keeping your software up to date, using a reputable antivirus program, and avoiding opening email attachments from unknown senders.
What is the most dangerous computer virus in the world?
There is no definitive answer to this question as it largely depends on a person’s individual definition of “dangerous”. Some people might consider a virus that is sophisticated and difficult to detect to be the most dangerous, while others might consider a virus that is relatively easy to detect but causes a lot of damage to be the most dangerous. Ultimately, it is up to the individual to decide which virus they believe to be the most dangerous.
Here is a list of some of the most notorious and damaging viruses in history:
The ILOVEYOU virus was a computer worm that spread via email attachments in 2000. The virus was particularly damaging because it replicated itself and propagate quickly, infecting millions of computers in just a few days. The ILOVEYOU virus caused an estimated $5.5 billion in damages.
The MyDoom virus was first spotted in 2004 and is considered to be the fastest-spreading email virus in history. The virus was spread via email attachments and infected millions of computers, causing billions of dollars in damages.
The Sasser virus was first spotted in 2004 and was a particularly damaging computer worm that affected mostly Windows XP systems. The virus caused widespread disruption as it caused infected computers to crash. The Sasser virus is estimated to have caused $18 billion in damages.
The Conficker virus was first spotted in 2008 and is considered to be one of the most sophisticated and difficult to remove viruses in history. The virus affects mostly Windows operating systems and is estimated to have infected millions of computers. The Conficker virus has caused billions of dollars in damages.
The WannaCry virus is a ransomware virus that was first spotted in 2017. The virus encrypts files on infected computers and demands a ransom payment in order to decrypt the files. The WannaCry virus is estimated to have caused billions of dollars in damages and has infected millions of computers in over 150 countries.
