Thanks for your reply Ursula,
It supposed to be a MP3 file, but doesn't let me check the properties, (right click) only play, open, import to adobe photoshop, add to WMP, edit with notepad, open with and send to. All other files give me totally different options, including virus check (a-squared, Bitdefender and AntiVir)

I blocked the incomming file for distribution for the simple reason I don't want to spread out incomplete, junk and or virus infected files. After checking I move them over to my distribution files (5722 at the moment)

It seems like this file: [Edit] K Type: MP3-audio file (MP3) Size 2.49 MB is infected.
Thanks for the tip, I will have to borrow another keyboard to start the safe mode because mine is USB.
