I downloaded Limewire a long time ago, did a few downloads and then erased the downloads along with Limewire itself. Well, recently I was online and then closed my browser and some folders appeared on my desktop that were labeled "lime-virusXXXXXXXX" (X's mean numbers). There was 3 of them. I put them in my trash, then downloaded ClamXav and searched for any infected files. There was only one and it was in my Safari cache. I erased that file and I thought I was done. Then today I was online again and then I closed my browser and in my desktop again were three folders and they say now Xx53728, XxX27635, Xx673892. What is this and what should I do??? Thanks.
