Search showing admin forum to users

[Lythena]

I have an issue where groups that do not have view rights to a forum still see the posts while searching. Is there a way to turn this off somewhere or am I missing a setting? Even when you are not logged in you can still search for admin posts and if they match they will show.

check groups permissions (again with care) for the individual forums

I just noticed that when editing group permissions eventhough the view is on disallowed then when you hit "Edit Permissions" there is again a "view threads in forum" option that is checked. Why is that there? It's double in my oppinion as it's the same as the View tag you can drag isn't it?
