I normally surf the net for the latest software, games and kind of stuff. Downloading and testing new games and software is my favorite time pass. Everything was working fine but now I think my personal computer is infected with W32 F Sasser Worm. I am trying to delete this worm from my computer but my antivirus is not able to delete this worm from my personal computer. I normally use free antivirus software available on the internet. So if possible suggest me antivirus software which are available for free.
