Different Types Of Computer Infection!

by: Silent One


When you listen to the news, you hear about many different forms of electronic infection. The most
common are:
Viruses - A virus is a small piece of software that piggybacks on real programs. For example, a
virus might attach itself to a program such as a spreadsheet program. Each time the spreadsheet
program runs, the virus runs, too, and it has the chance to reproduce (by attaching to other
programs) or wreak havoc.

E-mail viruses - An e-mail virus moves around in e-mail messages, and usually replicates itself by
automatically mailing itself to dozens of people in the victim's e-mail address book.

Worms - A worm is a small piece of software that uses computer networks and security holes to
replicate itself. A copy of the worm scans the network for another machine that has a specific
security hole. It copies itself to the new machine using the security hole, and then starts
replicating from there, as well.

Trojan horses - A Trojan horse is simply a computer program. The program claims to do one thing
(it may claim to be a game) but instead does damage when you run it (it may erase your hard disk).
Trojan horses have no way to replicate automatically.
