Well, that sounds like a faked file or even worse a worm/tojan/virus file. I reckon you check your computer with an up-to-date Av prgram and some Anti-Spy/Maleware program such as :
Spybot - Search & Destroy (FREE)

http://www.grisoft.com (free AVG program)

http://www.ewido.com (free trial version still usable and update-able after trial expires -the best on the market)

http://www.ccleaner.com/download/(free -will make your system twice as fast as before
