I'm wondering which Anti-Virus program to go with IF I should even bother. I've been a MAC user for years, and know that they are not really nessasary however my paranoia lately has been getting me. Especially the other day when I was surfing Olympic stuff and something jacked my browser (firefox) and I have to force quit to get out of it. I hate that they don't make an all in one. What are people using out there?
