Antivirus

I just learned something new....A MAC can get a virus. I have always heard that was one reason to buy a MAC. But they can get viruses and worms. So if you have a mac, you need an Antivirus for MAC. Huh? Who knew? Not me! But I don't own a MAC, so it hasn't been that important to me. I'm new to the whole Apple market, I just now got an iPhone. :)
