I need to completely restrict Internet browsing in one computer with Windows XP installed.
I have read many methods which imply editing the hosts file, using Internet Explorer filters, etc. The problem with these solutions is that they are not flawless unless you're running a limited account, which is not possible in my case.
Is there any software that restricts this kind of activity under, say, a password?
Thanks in advance.
EDIT: I'm running an admin account because the machine runs a POS (Point of Sale) software which cannot be run under a limited account.
