Hey guys, I got the same problem last week. What I did was uninstalled Limewire, ran a scan with Ad-Aware se and it did find things Spybot did'nt.After scan reinstalled Limewire and it ran fine.
One more thing, some asshollish german guy has just infected every file on limewire with the worm/wurmark. The actual file size is 851.7. Everything that I have tried to look for is nothing but this crap. If I find the guy, oh he's gettin an *** kickin. Good luck
