Quite annoying problem
 

Yesterday I've been downloading .torrent files and trying to open them using Limewire. (They didn't work if it's relevant). After I closed Limewire, it started again after a few minutes. I closed it, but since then, it's been popping up every few minutes. I tried restarting my computer. After that didn't work I unistalled Limewire. Now it's attempting to run, failing (since there's no program to run), and sending me an error message. How do I get rid of it?

Sounds like you may have become infected. Try this

AVG(free) might be able to fix it. Be sure to update it before you scan your computer: AVG Free Advisor: AVG Anti-Virus Free, then follow the prompts.

Once AVG has fixed the Problem you can delete it if you want to. AVG seems to catch problems other AV's don't catch.
Hope this Helps. :D
