What was the most dangerous computer virus of the 20th century?

It is difficult to say definitively which computer virus was the most dangerous of the 20th century. This is because there are a number of factors to consider when determining the level of danger posed by a virus. For example, the number of computers infected, the amount of damage caused, and the ease with which the virus can spread are all important factors.

One of the earliest and most notorious computer viruses was the Brain virus, which was released in 1986. This virus was particularly dangerous because it was able to infect both IBM PC and Apple Macintosh computers. The Brain virus was also notable for being the first virus to be spread via the Internet.

Another potentially dangerous virus is the Melissa virus, which was released in 1999. This virus was able to spread quickly and easily, infecting over one million computers within a matter of weeks. The Melissa virus also caused a significant amount of damage, with estimates of the total cost of the outbreak reaching $80 million.

Finally, the ILOVEYOU virus is worth mentioning as it caused significant damage when it was released in 2000. This virus was spread via email, and was able to infect millions of computers around the world. The ILOVEYOU virus is estimated to have caused around $5.5 billion in damage.

In conclusion, it is difficult to say definitively which computer virus was the most dangerous of the 20th century. However, the Brain virus, the Melissa virus, and the ILOVEYOU virus are all contenders for this title.

What is the most feared computer virus?

There are many different types of computer viruses, and it is hard to determine which one is the most feared. However, the ransomware virus is certainly one of the most destructive and feared types of viruses. This virus works by encrypting files on your computer and then demanding a ransom in order to decrypt them. This can be a very costly and time-consuming process, and it can result in the loss of important data.
