Thus, understanding the fundamental molecular processes used by viruses to conquer cells is important among these processes is the ability of molecules created by viruses to 'mimic' the structure. A computer virus is a program that spreads by first infecting files or the system areas of a computer or network router's hard drive and then making copies of itself some viruses are harmless, others may damage data files, and some may destroy files.
Creating a virus that spreads quickly is a little like that -- it creates a bomb inside a computer, and the more computers that get infected the more fun the explosion the third reason probably involves bragging rights, or the thrill of doing it. A computer virus is designed to reproduce itself and spread from one file or program to another, and, less frequently, to other computers on a network trojan horses masquerade as harmless programs, but when activated, they damage their host computer.
