What is the most dangerous virus computer?

There are many malicious computer viruses that have caused significant damage, but the most dangerous ones are those that are still actively spreading and causing problems. The most dangerous virus currently spreading is the WannaCry ransomware virus, which first appeared in May of 2017. This virus targets Microsoft Windows systems and encrypts files on the infected computer, making them inaccessible. The WannaCry virus then demands a ransom be paid in order to decrypt the files. This virus has caused major problems for individuals and organizations around the world, with estimates of the damage caused ranging from hundreds of millions to billions of dollars.

Another dangerous virus is the Petya virus, which first appeared in 2016. This virus also targets Microsoft Windows systems and encrypts files, but unlike WannaCry, it does not demand a ransom be paid for the decryption key. Instead, Petya directs victims to a payment site where they are instructed to pay $300 in Bitcoin. This virus has caused significant damage, with estimates of the cost reaching into the billions of dollars.

These are just two of the most dangerous viruses that are currently spreading; there are many other dangerous viruses and malware out there. It is important to have strong anti-virus and anti-malware protection on your computer, and to be careful about clicking on email attachments or links from unknown sources.
