forum hack? help!
 

My forum has completely vanished with the exception of the header.
http://editorunleashed.com/forum/

It's been missing for a week and I haven't found a solution. Just emailed VBulletin tech support for assistance.

A member just sent me a message that she had subscribed to a thread that showed activity on Dec. 26 and a link that led to handbagcom.com

It seems pretty clear to me that my site has been hacked and I'm not even sure where to begin with recovery. Any help* advice or a solution appreciated. Also would love to know if other VBulletin owners are having these issues.
