How are computer viruses created?

Computer viruses are created by people who want to cause harm to others, or who want to gain control over someone else’s computer. Sometimes, viruses are created accidentally, when someone is trying to create a program that is not supposed to be harmful. Viruses can be spread in many ways, including email attachments, file sharing, and websites that host harmful code. Once a virus is on a computer, it can spread to other computers on the same network. Viruses can cause damage to files, programs, and the operating system. They can also send messages or display fake messages to trick people into giving away personal information or clicking on links that install more viruses.

Do computer viruses ever mutate and become more dangerous over time?

Yes, computer viruses can mutate and become more dangerous over time. Just like any other virus, a computer virus can mutate and become more virulent. For example, the WannaCry virus that hit in May 2017 was a mutation of an earlier virus called WannaCry-MDSR. The WannaCry-MDSR virus was not as virulent as the WannaCry virus, but it was still capable of causing serious damage.
