It wouldn't technically be a virus since its not self-perpetuating. I believe that it would have fallen under the category Trojan, and there are already some of those for OS X. You should still be somewhat careful about what you download and run.Timepass said:It would not of effect a PC. Virus made for a mac have no effect on a Windows computer. Same goes the other way. It is one of the few times it would of been better to look at it though a PC since it can not be effected by it.
But this could just be a started. I wouldnt be surpised to see a real virus for the mac enter this way. It would not be wide spred becaue it how it needs to be activated.
