Hi, My partner downloaded DivX from the Internet, not sure if it was from the website or not so I'm thinking that I may have gotten some kind of virus from this.. I have 3 reasons for thinking this. 1) A couple of weeks ago I went to empty my trash and it was full of almost my entire itunes library. I didn't empty it and the next day the songs had disappeared from the trash. 2) My desktop picture changed by itself. 3) Although I thought I deleted DivX from my computer (I did a search of DivX on finder and dragged everything to the trash), notices have come up twice saying there are new updates for DivX... Either I have some sort of virus/malware or maybe I haven't properly deleted DivX, in which case how do I go about this? I downloaded Sophos Anti-Virus from the internet and it hasn't picked anything up so I'm not sure what's going on! Please help!
