I found a PC virus on my mac, I tried to open it absent-mindedly when it downloaded but obviously it wouldn't since it's an .exe file. It's not a threat right? I have Windows on my PC too, but it's on a NTSF partition through Bootcamp and I think that makes it inaccessible for the most part, right? Since the file wouldn't open it couldn't do damage I'm guessing. I use iAntivirus for my mac and know that it doesn't detect PC viruses. How I found this one was using Avast! while running Windows, and Macdrive allowed it to scan the mac partition. This should be an okay workaround right? Versus buying a mac anti-virus software that addresses PC viruses too. Thanks, I'm a new student to the world of anti-virus/spyware/malware.
