I have MacAFfee virus, spam and firewall. Nothing comes through to my computer that I have set my settings against. As for email I don't open anything from any email addresses. When looking at the in box of emails it tells you the subject line and email address it is from. any company sending advirtizements I don't open them, I just hit delete without reading them at all. Also any advirtizements sent to me to my aol, yahoo or hotmail addresses goes to my "bulk" files and spam filess. and they are automatically deleted by my email companies. I open the "files" just long enough to see if I recieved any newsletters from a couple on line goups that I am a member of and if one is there I move that one to my in box and delete the rest. getting advirtizements don't bother me. they want to waste their computer stuff sending them to me fine its their choice but I do not have to even open them. Its just like getting all those fliers and junk mail by snail mail (normal post office delivering to my house) get things from pizza hut to geiko and they all go in the garbage un opened and read. As long as I use common sense and not open email with addresses that I don't recognize I wont get a virus.
