You can add a line to your hosts file. This file is located in:

C:\windows\system32\drivers\etc\hosts

Open it with notepad and add lines like so:

127.0.0.1      example.com
127.0.0.1      Facebook.com

Make sure that you do not rename the hosts file when you are saving it. It is normal for it to have no extension.

When I am trying save modified host file, I obtain this popup window: Please check if this file is opened in another program and changes is not saved. I am close all programs (included browsers) but when trying save changes, result again none. –  OTARIKI Dec 5 '12 at 21:54

Open the "hosts" file in C:\Windows\System32\drivers\etc with Notepad (Windows 7). At the bottom of the text on a blank line add "127.0.0.1 www.example.com" without the quotations and then save the file. When you go to www.example.com it should no longer work. http://www.timeatlas.com/term_to_learn/general/taking_control_with_the_hosts_file

Also, some ROUTERs have parental controls features within the web interface. Sometimes you can add websites you want to block within the router configuration. –  j_bombay Dec 5 '12 at 21:45

Open C:\Windows\System32\drivers\etc\hosts with Notepad and add the following entries to it:

127.0.0.1 example.com
127.0.0.1 www.example.com

So all traffic to that sites will be redirected to your computer

Add it to your hosts file: 127.0.0.1 facebook.com

This should prevent your browser from doing a DNS lookup on the site, and instead point it at your computer's loopback address. If your computer is running IIS and has a default website, you'll get that, if not you will get an error that the page cannot be found/displayed.

You'll want to add it to your "hosts" file to block it:
