Hey Bill,
You can always use your "hosts" file to block DNS names and/or IP addresses.
C:\windows\system32\drivers\etc\hosts
Open with Notepad and make an entry like the following:
127.0.0.1 porn4porn.net
127.0.0.1 porncamz.com
127.0.0.1 pornclipstube.com
127.0.0.1
www.pornclipstube.com 127.0.0.1 pornfree.info
127.0.0.1
www.pornissex.com (there is supposed to be a "tab" space between the IP address and the DNS name)
The IP address, 127.0.0.1, is called the IP Loopback address. It routes flow back to the network card itself (never goes out to the internet).
A lot of malware/spyware programs do blocking this way.
