A computer virus is a program that Infects part of the system. Causes some sort of damage or data loss. And produces copies of it to spread to other computers some viruses have been known to destroy the data structure of an entire hard drive or even to damage the infected computer’s BIOS chip (without which a computer doesn’t work at all); others simply target and destroy one type of file, such as program executable or documents.
