Ad Close Description:

Ad Close was designed to close windows that suddenly open. For
example such annoying browser windows as: "Some words from our
sponsors..." which open while you are browsing the Net. It also
has the ability to protect your children from sexually explicit
material on the Net, by closing windows with specified keywords
in title of the windows.

Even more, you can create a folder named "John`s", then add to
Children protection list "John`s". When children protection is
enabled, NO ONE can open your folder.
