Another option is to edit the hosts file.
Do Start, Run, then type:
notepad C:\Windows\System32\drivers\etc\hosts
and hit Enter.
You'll probably see a file which looks like this:
Quote:
# Copyright (c) 1993-2006 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
127.0.0.1 localhost

Add a new line, for example:
127.0.0.1
www.siteyouwanttoblock.com
and save the file.
Your PC will not now be able to connect to any page at the siteyouwanttoblock domain.
