If you want to block your computer access to forbidden sites, maybe some software that can help:
Anti-Porn
Able to block the site or content, including not displaying pornographic images that are considered odorless and replace it with a picture antiporn.
NetDog
This software is very light. How it works he did not close the browser, but will not work (not loading) when the browser used to access porn sites. Blocking can be done by adding the words (keywords) or a particular site. Besides it can also be an exception to the words and the particular site.
SitusiteBloker
This program depends on the database. So if you have a data base that much about web porn, it will be more perfect way. The surplus of this program can be hidden and you can set a warning message in any way you like it when used to access porn sites.
