Well, I have to thank Bill for keeping Redmonds hands off of anything to do with my Mac OS X operating system. Well, almost: he did buy Virtual PC, the Windows emulator program for OS X, and distributes this to unsuspecting Mac owners so they can - oh joy, oh rapture - run Windows on their Macs and thus be vulnerable, but other than that there doesn't seem to be any way to catch a Windows virus on the Mac, and there aren't any viruses that are ''native'' to a Mac - not one. That, of course, hasn't stopped Norton's Symantec and others from capitalizing on the public's fear of viruses, so lots of Mac owners have antivirus software, oblivious of the fact that all it does for them is gum up the works and slow their Macs down. When I make a service call, the first thing I do is advise the client to REMOVE antivirus software from their Mac.
Seriously, the only possible value of antivirus software on a Mac is to strip off viruses from files passed on to them by unimmunized Windows machines. While those viruses are inert on a Mac, they CAN infect Windows machines if the Mac owner, himself, passes on the file. Sort of like a veterinarian who fails to wash her hands after handling a dog with a transmissible (canine only) disease. She can't catch the disease herself and she can't infect a cat, but she might infect the next dog that hasn't been immunized. Of course, we could immunize the vet and every other creature that's innately immune to the disease - cats, horses, cows and hamsters - but a saner strategy is just immunize all dogs. In line with that analogy, it makes much more sense to put virus software on all PCs (dogs), then to do so on a Mac (cats).
Of course, some people think cats - Jaguars, Panthers, and Tigers - more elegant than jackals, wolves, cayotes and hyenas, but that's an entirely different discussion, unrelated to this virus issue. :-b
