Sometimes in schools,colleges or net centres surfing some sites like orkut,facebook are blocked.So here is a process to block or unblock any website.
For eg: If you want to block www.abc.com
>>For default users,Go to directory C:\WINDOWS\system32\drivers\etc
>>There you will find a file named hosts
>>Open the file ,when you get open with program list then select notepad and open the file using notepad
>>Now in the file you can see 127.0.0.1 localhost Click enter and type any proxy number Eg:127.0.0.2 www.abc.com
>>Now go to file and save it
>>Now when you open www.abc.com you will be transferred to 127.0.0.2 site which is not there So www.abc.com will not load
*This will not load in any browser of your PC untill that site is removed from hosts file by using notepad(Unblocking)
