What is Computer Virus

Hi all, since I'm doing this blog for all kind of audiences, (newbie, school kids, armature or even the pro) so I think nothing wrong to make a posting on "what is computer virus?" Although this issue is not a hard issue on us but for some very newbie it's pretty important for their computer care. So I hope the armature and the pro won't be blown up by this posting. ha ha ha.

This is the precise description and hope it will help the real newbie out there.

A Computer Virus is a computer program which distributes copies of itself, even without permission or knowledge of the user. A computer virus is often simply called a virus if it is clear from the context that it does not refer to a biological virus. The term is commonly used to refer to a range of malware, but a true virus does not need to be harmful. To distribute itself, a virus needs to be executed or interpreted. Viruses often hide themselves inside other programs to be executed.

The term comes from the term virus in biology. A computer virus reproduces by making, possibly evolved, copies of itself in the computer's memory, storage, or over a network. This is similar to the way a biological virus works.

Computer virus could spread in such rapid from file to file or even partition. one of the example is Brontok.
