No viruses for my linux computer, so loads of save downloading for me, WOOT!
You cant have a virus made to take down a anti-virus program, such actions require someone to directly break into your computer to disable it. If there ever was one such as you described, having multiple anti-virus programs will defeat the virus before it ever attacks its target.
