I downloaded a movie from Limewire. I can't delete it. I keep being told it's being used - even after I restart.

I have moved it to another folder unrelated to Limewire but STILL CAN'T DELETE IT!!


And when I select it to try to delete it, my CPU usage goes up to 100%!!

I want to get this cr*p off my PC but don't know how!!

HELP!!
