I'm on a Mac, but I have to admit that for the first time in my entire computer using life, we had a virus on one up until yesterday. It was on my safari, buggered up my google (kept defaulting to bing, even though I set google as the preferred search engine...) I don't remember exactly what it was but it had minbari in its name... and it was targetting OSX specifically. If that helps you at all....... (I'm not saying I got the virus from here, but I did apparently download it from someplace)
