Greetings:
PC Magazine is a wealth of information on products, methods, and tips. In the June 2012 issue, there is a column describing how to block websites so that nobody can access them from any browser. There are firewalls that can do the job, but this is more fundamental - and easy as well.
Blocking all users of a Windows PC from opening certain websites--no matter what browser they use or what time of day they are online--is easy if you follow this guide to tweaking your browser and router.
