Site will not load: Fatal Error

[RedKnight]

I know little about PHP, but I'm pretty certain nothing was changed in the admin control panel when this stated, but the site will no longer load and displays the following error:

Fatal error: Cannot redeclare tg1() (previously declared in /homepages/37/d218094137/htdocs/x-fan/xfan/index.php(1) : eval()'d code:1) in /homepages/37/d218094137/htdocs/x-fan/xfan/forums/includes/config.php(1) : eval()'d code on line 1

Does anyone have any possible course of action for this problem?

Hmmm, check your config.php file and make sure there is nothing in there regarding tg1(). Something looks fishy about that error.

It appears to be some sort of viral attack. We have had someone correct the problem, but it pops back up from time-to-time.
