Most of you are not aware that I am a recovering PC-holic. I've never owned a Mac before but have my first one on order (w/ 4850...but that's another thread). Is it true that antivirus software is not really needed with a Mac? I do not do pron sites but do go to TPB some but mostly for videos but not apps. So, if I need AV, what are the good (cheap) ones? What about spyware/malware?
