What are some of the most deadly computer viruses in history?

In computing, a computer virus is a type of malicious code or program written to alter the way a computer operates and is designed to spread from one computer to another.

The term “virus” is also commonly used more broadly to refer to other types of malware, including spyware, adware, and ransomware.

While viruses can be used for malicious purposes, such as causing damage to a computer system or stealing personal information, they can also be used for more benign purposes, such as displaying jokes or political messages.

Some of the most deadly computer viruses in history include:

1. ILOVEYOU

The ILOVEYOU virus was a computer worm that spread via email attachments in 2000. The virus would email itself to everyone in the victim’s address book and would replace important files with itself, making the system inoperable. It is estimated that the ILOVEYOU virus caused over $10 billion in damages.

2. Melissa

The Melissa virus was a computer worm that spread via email attachments in 1999. The virus would email itself to the first 50 contacts in the victim’s address book and would display a message that said “Here is that document you asked for…don’t show anyone else ;-)”. The Melissa virus is estimated to have caused over $80 million in damages.

3. Code Red

The Code Red virus was a computer worm that affected Microsoft’s IIS web server software in 2001. The virus would spread by replicating itself on vulnerable systems and would launching denial-of-service attacks against the White House website. It is estimated that the Code Red virus caused over $2 billion in damages.

4. Nimda

The Nimda virus was a computer worm that spread via email attachments and infected web pages in 2001. The virus would email itself to everyone in the victim’s address book and would also infect any web pages that the victim visited. It is estimated that the Nimda virus caused over $745 million in damages.

5. MyDoom

The MyDoom virus was a computer worm that spread via email attachments in 2004. The virus would email itself to victims and would launch denial-of-service attacks against websites belonging to Microsoft and the SCO Group. It is estimated that the MyDoom virus caused over $38 billion in damages.

What is the most popular computer virus?

The most popular computer virus is the WannaCry virus. WannaCry is a ransomware virus that was first discovered in May 2017. It quickly spread around the world, causing widespread damage. WannaCry encrypts a victim’s files and demands a ransom be paid in order to decrypt them. The virus was particularly damaging because it exploited a vulnerability in Microsoft Windows. WannaCry is estimated to have caused over $4 billion in damage.
