Anti Virus Software Compared
About Viruses, Trojan Horses etc.
What is a Virus?
A virus is a manmade program or piece of code that causes an unexpected,
usually negative, event. Viruses are often disguised games or images with
clever marketing titles such as "Me, nude."
What is a Worm?
Computer Worms are viruses that reside in the active memory of a computer
and duplicate themselves. They may send copies of themselves to other
computers, such as through email or Internet Relay Chat (IRC).
What is a Trojan Horse?
A Trojan horse program is a malicious program that pretends to be a benign
application; a Trojan horse program purposefully does something the user
does not expect. Trojans are not viruses since they do not replicate, but
Trojan horse programs can be just as destructive. (source:
