What is the most deadly computer virus in the world?

There is no definitive answer to this question as it largely depends on individual circumstances. However, some of the most deadly computer viruses in the world include the following:

1. WannaCry

WannaCry is a ransomware virus that was first released in May, 2017. It quickly spread across the globe, affecting hundreds of thousands of computer systems in 150 countries. WannaCry encrypts files on an infected computer and demands a ransom be paid in order to decrypt and regain access to them. In some cases, the virus also Locky and Petya. ransomware has been known to delete files if the ransom is not paid within a certain time frame, making it incredibly dangerous.

2. ILOVEYOU

ILOVEYOU is a virus that primarily targets Windows users and was first released in 2000. The virus spread quickly via email, with victims receiving an email appearing to be from a loved one or friend. The email would contain the subject line “I love you” and would contain an attachment. Once opened, the attachment would launch a script that would overwrite vital system files and send itself out to everyone in the victim’s address book. ILOVEYOU caused an estimated $5.5 billion in damage and is considered one of the most destructive viruses of all time.

3. Code Red

Code Red was a worm that primarily targeted Windows web servers and was released in July, 2001. The virus exploited a known vulnerability in Microsoft’s IIS web server software and would give the attacker complete control over the infected system. Code Red was particularly dangerous as it would launch a denial of service attack against the whitehouse.gov website. The virus caused an estimated $2 billion in damage and infected over 359,000 systems.

4. Meliss

Meliss is a virus that was first discovered in 2009 and specifically targets Mac OS X users. The virus is spread via email and, once opened, would install a backdoor on the victim’s computer, allowing the attacker to gain remote access. From here, the attacker could then stealing sensitive information or infect the system further with other malicious software. Meliss is considered particularly dangerous as it can be difficult to detect and remove.

5. SoBig

SoBig is a virus that primarily targets Windows users and was first released in 2003. The virus is spread via email and, once executed, would email itself out to everyone in the victim’s address book. SoBig would also harvest email addresses from any files it could find on the infected computer. The virus caused an estimated $37 billion in damage and infected over 500,000 systems.

What was the most widespread computer virus in history?

The most widespread computer virus in history was the Morphis virus. It was first detected in the wild in January of 1999 and quickly spread around the world. By the end of the month, it had infected over six million computers. The Morphis virus was a destructive virus that would reformat a hard drive, making it unusable. It would also delete all of the files on the hard drive, making it impossible to recover any of the data. The Morphis virus was spread primarily through email attachments and was eventually contained by a patch that was released by Microsoft.
