Undeletable file!! (being used by another person or process) FIX!!!

[teddyFBI]

So I downloaded a movie (non-porn, although that's irrelevant for these purposes) from Limewire the other day. Tried to play it, but Windows Media Player said it couldn't because the file was corrupt or otherwise non-playable format.

So I figured "oh well" and tried to delete it. Except I can't -- it tells me that the file is currently being used by another person or process. Fair enough. So I restart my computer. Still can't delete it!! I even start it up in safe mode (so only the most essential functions are running in the Processes menu. STILL, it tells me that the file is in use and can't be deleted.

I'm annoyed, but also concerned b/c you never know what you're downloading when you get random Limewire files. How do I get rid of this thing??

(I did full system antivirus and spyware scans, everything came up clean)
