I have a roomate that has been in adult sights and has
tried to delete all the files and has done so but the
problem that is still there is that these URL's are still
on my address bar and I can't seem to take them off and I
have a child that should not be able to enter into these
sights. Please tell me how to delete these from the
address bar.
