on the grounds that there are no virus's out there that operate against OS X.
If you want to feel warm and fuzzy, or are just missing the need to use AV software, then you could take a look at CLAMXAV, google it.
It's free and does not eat processor cycles like the ones from Symantec and Mcaffe.
It detects Windows virus's too, but they do not operate on your Mac. It's just so you will not send them on to your less fortunate friends
Hi! I 'm a new mac user and always had PC's (MICROSOFT !!) before with a blizzard of anti-spy and virus requirements to check and update all the time - like Norton. Do I need to buy a separate program for my MAC to check spyware installation, stealth installation of keystroke "capturers" , viruses etc? What do you experts recommend? The folks in the apple store at the genius bar said they didn't use one.
My system is: imac 2.8 ghz intel machine w / 2gig memory, version 10.5.8 installed and all apple software updates done. I don't download other programs other than adobe and am not a gamer.
Thanks in advance smart folks out there!
