Block Any Website

Now you can block any websites in your system Without any software.
Step 1 : Go to "C:\WINDOWS\system32\drivers\etc"

Windows 95/98/Me       - c:\windows
Windows NT/2000/XP Pro - c:\winnt\system32\drivers\etc
Windows XP Home        - c:\windows\system32\drivers\etc

Step 2 : There would be a file named "hosts"
            (Note : This file have no extension.)

Step 3 : Open the file in Notepad.

Step 4 : There will be some content of copyright informations.
            Goto the last line of the file.

Step 5: That is 127.0.0.1 localhost

Step 6: Now add a new line as shown below.
            127.0.0.1 www.xyz.com
            (This line will block the 'www.xyz.com' in your system).

Example:
127.0.0.1 localhost
127.0.0.1 www.xyz.com
127.0.0.1 www.orkut.com
127.0.0.1 www.facebook.com
127.0.0.1 www.yahoo.com
127.0.0.1 www.google.com

Step 7: Save the file.

Note : You should be sure to save the file with no extension. Sometime notepad will automatically add a .txt extension. So you should give the filename with the quotation “hosts”.

Now close all browser windows and open a new browser. Goto www.xyz.com OR www.orkut.com. Browser will never open that website. That means you are successfully blocked these websites. You can add any number of websites in that file.

TO UNBLOCK:
Unblocking is simple. Just open the 'hosts' file.
And delete the line which you want to unblock.
