How about changing your DNS servers so it can block porn and other unsafe websites from being accessed on your computer? It can be done with ScrubIT! It works just like OpenDNS where you have to configure your DNS servers.

If you want to configure it manually, the DNS servers to use are:

67.138.54.100 and 207.225.209.66

“ScrubIT is a FREE recursive DNS server that regulates what comes into your home or business. ScrubIT “scrubs” the internet so you don’t have to be concerned about what your family members or employees will be confronted with.

We currently profile several million websites and by default block out any pornographic, phishing, and many other potentially harmful sites. Users who wish to customize which sites are blocked and allowed may sign up for our BETA and customize their ScrubIT experience.”

The service is of course free. See more about ScrubIt here!
