What is the most dangerous computer virus and why?

The most dangerous computer virus is the WannaCry virus. It is a ransomware virus that encrypts files on your computer and demands a ransom to decrypt them. It is spread through phishing emails and exploits a vulnerability in Windows. It has caused billions of dollars of damage and has affected hospitals, businesses, and individual users.

What was the first computer virus?

In computing, a virus is a malicious code or program that self-replicates by copying itself to another program, computer boot sector or document. The term “virus” is also commonly, but erroneously, used to refer to other types of malware, including adware and spyware programs that do not have the ability to self-replicate.

The first computer virus is believed to be a program called “Creeper”, created in the early 1970s. Creeper was designed as an experiment to demonstrate how a self-replicating program could spread across a network. Unfortunately, the code was leaked and got into the hands of malware authors who used it to create malicious programs.

One of the earliest known examples of a computer virus being used for malicious purposes was the “Elk Cloner”, which infected Apple II computers in 1982. This virus was spread via floppy disk and would display a message on the screen when the infected computer was booted up. It read:

“Welcome to the Dungeon. Beware the Elk Cloner.”

Today, computer viruses are much more sophisticated and can cause serious damage to both individual computers and networks. They can be spread via email, the Internet, infected websites and even infected USB devices. Many viruses are designed to steal personal information or hijack computers for use in botnets. Some, like the “WannaCry” ransomware virus, can even encrypt files and demand a ransom be paid for the decryption key.
