My forums lead to Google search when browsed from a mobile phone

My Forums Checkthisup[dot]com lead to this page file07.com then redirect users from mobile devices to google search.

I have been trying to figure this out but cannot find out where the problem is.

Please help me.

My Forums are under Vbulletin if that helps.

Thank you

 

Sounds like a redirect hack, I'd read over this thread to find out how to remove it.

Thank you for the link. I did go to the site. I tried everything they suggested but It's still not working.
