Boot to safe mode and try deleting it
If you downloaded it from a program such as limewire or a torrent client, delete it within the client itself

Same thing happens to me with some files. Just do what questolo said.

* Restart your computer
    * After hearing your computer beep once during startup, but before the Windows icon appears, tap the F8 key continually;
    * Instead of Windows loading as normal, the Advanced Options Menu should appear;
    * Select the first option, to run Windows in Safe Mode, then press Enter.
    * Choose your usual account.

Here's some alternate instructions if you need it
