Someone hacked me, uploading a file: 978-mmm.php.wmv

Can someone view this file to identify the threat and how does it works?

Cause i need to deleted the threats...forum home still showing the "hacked index" and im trying to find where it's located.


Thanks

Edit: Now i know how does it works.....i deleted the file cause it's too dangerous....

JorgeX,
this is a PPvBgallery bug
check all files on your server...
