In principle. Its another Trojan, and presumably some Macs are vulnerable, and presumably it isnt in Apples directory of bad apples yet.But thats the thing - having a (Windows) system which was vulnerable to viruses made me paranoid - and, being paranoid, I was easily spooked into falling for a Trojan.
Its so much better to feel secure against viruses, and therefore be that much less susceptible to trojans.
