virus

A computer virus is a type of malicious software (malware) that is designed to replicate itself and spread from one computer to another. It can infect a computer and cause harm to the system by deleting files, stealing personal information, corrupting data, and even rendering the system inoperable.

Viruses can be spread through various methods, such as email attachments, infected software downloads, and malicious websites. Once a virus infects a computer, it can spread to other computers on the same network or via removable storage devices like USB drives.
