please help me removing the unwanted link.
Your site has been comprimised. It sounds like an SQL injection. Hopefully you have a backup of the site files/database prior to it being hacked.
Hacks in Joomla sites are 99.9% of the time related to a site owner not updating to the latest versions of both the core Joomla system and (more often) not keeping 3rd part extensions up-to-date.
The best things to help prevent/monitor that is to subscribe to the Joomla! Security News and the Vulnerable Extensions List.
If you have maintained backups of your site, it should be fairly easy to correct. If not, then the manual process of cleaning the infected files/tables may take quite a long time depending on how large your site is. To my knowledge, there is *not* an automated tool to do this for you.
Dear mlipscomb thanks again.For nice Reeply.
You need to remove/replace your facebook module (FB LikeBox FanPage). It has two hidden links for this fucking site.
