Do i Really need virus software on a MAC? I just switched to a MAC a month ago (love MAC). The rumor among PC users is that MAC users don't need to use virus software b/c there are not any MAC viruses. True or False? I am thinking it is not worth getting it b/c of the lack of viruses and the fact that Time Machine backs up my mac every hour. If i do get a virus... i can just restore my comp to an hour previous to the virus. Would the virus software just spare me the hassle of restoring threw Time Machine? Its a pain in the ass to fix a PC after a virus... but i don't think it will be such a hassle on my MAC. If i do need virus software for my MAC... What exactly will it do that i cant fix with a simple restore threw Time Machine. What software should i get? On a PC i did things like... registry cleanup, defraging hard drive, etc. Do u need to do things like this on a MAC?
