I am worried about my mac getting viruses, i know they are less likely too, but i am worried about my security. I was wondering what is a really good virus program for mac. I have Clamxav and it runs really well on my system, but the question is it as reliable as the commercial products for the pc and mac!? I also tried sophos, but it seemed to slow my mac down quite a bit! How reliable is clamxav?
