My forum is hacked
 

Hello*

one of my administrators username / password was stolen.
By the checking the log-file . the hacker modified couple of my templates.

I'm now unable to access my index.php home page
I get this message

Parse error: syntax error* unexpected T_STRING in /home/medkaau/public_html/vb/index.php(565) : eval()'d code on line 2

my website is www.medkaau.com/vb

The inner pages and other functions of the forum are working fine.
e.g. http://www.medkaau.com/vb/forumdispl...prune=-1&f=116

no changes occurred to any of my VB files (as far as I know).

How to fix this?

Thanks*
