First of all scan for viruses before anything else.

If they are torrent files, make sure the program that uses them (bittorrent?) is closed. They could be incomplete downloads perhaps?

Try to delete the files in safe-mode. Restart the computer and keep pressing F8 until you get the boot menu.

Perhaps the all-seeing eye on your DESKTOP just doesn't like you? Novus Ordo Seclorum, as it likes to SAY. Ok SCANNED for viruses and no good there. And they aren't torrent files, they are some wierd replica that my computer created when i DOWNLOADED a torrent file without its extension. I also TRIED the safe mode thing and it didn't work. I need like a program that will delete wherever it is on my hard drive that is saying there is a file there despite the fact there isn't. (I know thats kinda confusing) :-/create a new folder and drag them into it...........you can it reports?? so re-boot pc and then try again and delete the folder or the files...........Try to delete them in safe-mode.Download Eraser here and erase them!! (Freeware)
