Also, everything I read online suggests that A/V for the Mac is a waste of time. Now I am a natural skeptic, and firmly believe that it is only a matter of time before market share drives the Mac to be more of a hacking target. Yet many highly reputable sources continue to state that the basic design of OSX is bullet proof. Your thoughts?
I would say atm it is bullet proof unless the user makes some stupid mistake (Mac Defender anyone?). If you buy applications from reliable sources, same with other content in your Mac, if you don't visit "queer" pages, if you don't open attachments of mails from unknown recipients and so on.
I'm using Mac's since early 90ties and my Mac actually caught virus once, I believe in 1996! It was called "Worm" and main symptom was that computer got slower and slower. It was very much easy to get rid of it, I got the virus from a friend whom brought me some apps on diskettes heh.
Why I even use AV at the moment? I don't know. It's for the fun of testing more than anything else I guess. And it's nice to be 100% certain I won't distribute some Win virus in job (I take my Mac into job to work on it and I move files to jobs crap Dell PCs). Without AV I'm only 99.7% sure.
