I was in the same boat that you are in. I ran my Mac for a month without any virus protection. I got a little scared and I got Norton Virus protection. In the several months since I have Norton, I have not seen anything on my system. I will not renew Norton.
This weekend I will be making the official plunge in the switch from PC to Mac. I haven't used mac too much and don't know nearly as much about mac as I do PC. So I was wondering, Do I need some kind of anti-virus or anti-spywear for the mac? If so what kind.
Sorry if this is a really stupid obvious question.
