Here is a simple trick to block any website .
[I found it while browsing through the windows directory and took a bit help from the internet :-) any way check it out.]
1] Browse C:\WINDOWS\system32\drivers\etc [or just paste it into the addresbar]
2] Find the file named "HOSTS"
3] Open it in notepad.[Don't tell me how :-D]
4] Under "127.0.0.1 localhost"
Eg: 127.0.0.2 www.google.com
more example :
- www.orkut.com is now unaccessable
For every site after that you want to add, just add "1" to the last number in the internal ip (127.0.0.2) and then the add like before.
IE (not internet explorer ,it is "That is"):
HURRAY THE SITES ARE BLOCKED.
