Is it possible to remove the 'classifieds' link for logged in users from the backend

Hi,
when a user is logged in they have access to their profile - which is fine. However the profile is in the backend and once there there is a classified link/section. I don't really want them to be able to click any of these classifieds links in the backend - I want them to do all this in the front end as it is a bit confusing. Is there a way to remove the classifieds link from the backend?? I am using the ultimate branding plugin but I can't see how I can do this with it.

Thanks Jo
