DO NOT use 2 anti-Virus programs on a computer. They will conflict with one another.

Ditto for firewalls.

But you can (and should) use several (anti-)spyware programs (Spybot and Ad-aware are great).
but of course, its the same as having two word processors in the same machine. The problem begins when those 2 programs begin to ''atack'' each other, very much like the early versions of explorer and netscape.
