I think I speak for everyone when I say nobody really cares about differentiating between viruses and other forms of malware. It's a case of splitting hairs.

Nobody at the Apple depot was ever able to determine just what exact kind of malware it was that crippled my mother's Mac beyond any cost effective repair but it did happen last year and she was forced to buy a new one. I educated her about the dangers of just roaming around all willy nilly clicking on anything and everything and she has suffered no issues since then. That's all anybody really cares about.

As time goes on and Macs become more commonplace we will see more Macs being targeted. Which methods are used in those attacks is generally irrelevant to John Q Public.

I am surprised they just didn't erase her hard drive and reinstall. If you go to the Apple store here they do that stuff at no charge but its best to make appointment at the Genius Bar for it. Better yet run Time machine on a second drive that takes care of anything where you can do it you self at any time.

And I get much more enjoyment out of my guitar
