Avoiding viruses


There are several different methods that can be used to stop viruses getting in, out, and around networks.
In this page I will describe some of them. To start off with, here are some terms:

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.
Many people use the term to refer only to non-replicating malicious programs, thus making a distinction between Trojans and viruses.

Exa uses the McAfee range of products to combat viruses and worms, as can be seen by the diagram below.
