file with no extension, 0 bytes

As the title says. How to get rid of this f*****?! File name: CAVE76B1. and few others.

Some idiot downloaded bunch of mp3, together with this crap. Rename does not work, dir shows "no file found"...
Scanned the disk, found nothing. Can't leave it there, the bastard left few it in few directories (with, obiously, I cant remove).

Help!

>>7 is an asshole, don't listen to him. He lies.
