robinpen on "Hidden embeded third party a href tags"

Hi.. My site recently had an link added from a third party GLOBloans.com. It is showing on all my menu pages. When I tried to edit an indivual page the a href is not showing it seems to be invisible to Wordpress. I can't find where it has attached itself. Couldn't find it on the CSS file, or index.php, and am not sure how review the SCL database. Has anyone else had this problem? If I have the exact a href code how can I search or located in WP?
Thanks for your help
