I have been running my computer antivirus free since August '04. I am using a popular firewall (ZoneAlarm) and running anti-spyware software (AdAware & SpyBoy) on a regular basis. My question: is it really necessary to have AV? I have not encountered one problem involving a virus, which I know doens't mean there isn't one, it just hasn't effected my operation.

The reason I don't have the software is because my CD drive was busted for the longest time and I never got around to downloading any free software. Now that my drive is fixed, I am about to install Norton '03 just to be 'safe'.
