ACH!!!

So... I downloaded this file that was supposed to be an .avi of Star Wars Ep. III (filename: Star.Wars.Episode.III.Revenge.Of.The.Sith.WORKPRINT.XviD-CENTROPY.avi). It says it's 700 mb or so. It downloaded in like... less than a minute. Not possible on my connection EVER. So before doing anything else, I run Norton AntiVirus on the file... comes up clean. I try to play it - won't play initially. I open it in VLC media player - 'cause that'll play almost anything. It's a short, crappy clip of someone doing some motocross bike flippy trick and landing on his ass. Windows Explorer still claims the file is 700+ mb, but it only takes up 3.55 mb of space on the disk. WTF? Oh... wait... I lied. It's back to claiming it actually does take up 700+ mb on the disk again. But I know it doesn't. But... the important part...

I CANNOT DELETE THIS FILE NO MATTER WHAT I TRY!!! It tells me the file is in use by another person or program. I shut down every effing program that was running, short of shutting down Windows itself, and tried deleting again. Same message. I booted up in safe mode and tried deleting again - same message.

What is this thing? How do I get rid of it? Scans for viruses and adware and spyware turn up nothing. I'm at a loss.

I WANT THIS PIECE OF WHATEVERTHEFUCKITIS OFF MY COMPUTER!!

Anyone have any ideas??
