Computer Virus..

A computer virus is a computer program that can copy itself and infect
a computer without the permission or knowledge of the owner. The term
"virus" is also commonly but erroneously used to refer to other types
of malware, adware, and spyware programs that do not have the
reproductive ability. A true virus can only spread from one computer
to another (in some form of executable code) when its host is taken to
the target computer; for instance because a user sent it over a
network or the Internet, or carried it on a removable medium such as a
floppy disk, CD, DVD, or USB drive. Viruses can increase their chances
of spreading to other computers by infecting files on a network file
system or a file system that is accessed by another computer.
