I understand that visiting this site may harm my computer.



Even if you use the latest versions of Community Builder (v1.2) and Joomla (v1.0.14) then you're vulnerable to a hack.  Watch for users signing up with the .ru top-level domain as they love playing this about and giving all russians a bad name on the net.

If you visit your site and receive either the above error or the alert that a malware was detected: congratulations! you've been hacked.

So first of all check that this is not just a hack to your index.html file in your web root folder (you may find a .heder.php file as well in your webroot as well as some strange index files with strange naming conventions (eg. xzcseifs_kdiek.html) which shouldn't be there either).  You'll need to remove these and restore your website.  I'd suggest joomlapack if you're using a joomla site, backup just the database, do a fresh install of joomla and use the database sql file as the migration script.
