Our site redirecting to some search engine

[FockerFGAA]

With users that have firefox they are coming to the site and then being redirected to yandex.com (some russian search engine). I have ran a virus scan on the site and it was clean. I ran a trojan scan and it can back with possibilities but nothing for sure. It only does it in firefox. It also pops up a malware issue for some users. I have tried refreshing my browser cache and it still does it. If you go to www.fvsports.com through firefox you will see what I am talking about. I have a deal open with my host, but if anyone here has a good idea of what it would be it would be greatly appreciated.

Same thing is happening to my site as well.

What the hell is going on?

Changed files usually indicate that the hosting account was compromised.

First step to take in a situation like this is look for changed files. This can be done from the AdminCP -> Maintenance -> Suspect File Versions.
