computer virus | Definition

A computer virus is a type of malicious software that is designed to replicate itself and spread from one computer to another.

It can infect a computer by attaching itself to a program or document that is then circulated, or by being downloaded from the internet or another network.

Once a computer is infected with a virus, the virus can execute a variety of harmful actions, such as deleting files, stealing personal information, or using the infected computer to attack other computers. Some viruses are designed to cause damage to a computer’s hardware or software, while others are created to cause inconvenience to the user.
