Help please? Weird problem..

[Blargh]

Ok, here's the story. My computer broke down and I lost all my files. So after getting it back I redownloaded limewire and downloaded some music files I was still missing. After doing so the program all of a sudden started sharing every file on my computer. I clicked the configure button but the window would not pop up. I became a bit frightened and exited the program but to my dismay found that it started itself back up again. I uninstalled it, but now this little java box pops up saying that the files are invalid, telling me the program is still trying to start up even though it's been uninstalled. I've also tried restoring my computer to before I downloaded, but that didn't work either. I ran a virus scan and such to determine whether or not I'd downloaded a virus, worm, trojan or any such thing as that, but results were negative.
The box:
