I read a technibble article recently saying "macs need virus protection too" --> I disagree. It's MUCH more often I see AV apps causing problems on Mac then protecting them from viruses. Anytime I see AV software on a client's computer, and it's in for a tune-up, I uninstall them. Yes, there is a possibility of some minor virus affecting your Mac, but it's unlikely, and HIGHLY publicized and easy to remove when found.
*The only reason IMO to run it is if you are exchanging many doc files with PC people and you don't want
them to get macro viruses.
Someone must disagree
