Javascript Hack?
 

A injected Javascript hack or bad ad is redirecting my traffic to http://filestore72.info - Is there away to stop this from happening, I have vbulletin 4.2.5

Yes, you will need to locate & remove the code they added, most likely a plugin.

You'll also need to try & track down how they injected it, apache logs may help you there.

This infection is pretty common, they infect your datastore, usually a few .php files on the server and sometimes create a new hook that contains a backdoor.

Remove it, then clear the system cache so the datastore is cleared.

Your site got malware and you need to check your script carefully + a fresh install for it.
