"Now I am disconcerted. I asked for help because I had a virtumonde and it seems it has been removed, but I don´t know where it could be. We have unistalled emule but I had downloaded it from a trust web (http://www.emule-project.net). I try to be very careful with that. We have moved utorrent but it was also downloaded from a trust web (http://www.utorrent.com/). Finally all the archives and folder deleted were installation programs, not programs running in my PC. Have you some specific idea?"
There was only some traces of virtumonde in your computer. As for P2P programs, they are against forum policy so I won't help/comment anything about them.
Any malware issues left?
