I saw a couple instances of this running in the background, totally using up all of my resources; I deleted them, but have no idea what they are. I had a virus earlier in the week. Google didn't show up much.
Well, just going by the URL from the only Google result, my best bet would be that fiks.exe is some form of trojan/virii/exploit software. See if Spybot Search and Destroy or Adaware detects it as anything. If not, just manually delete the file.
