how to unblock websites from my computer?

[ATUL]

Unblocking method will depend on type of blocking done by your brother !

- If he is using any sort of software to block access you can simply bypass denial by killing that app from task manager.

- If he is using DNS method .. check C:\Windows\System32\Drivers\etc\host file .. if blocked sites were listed there . Delete the lines
127.0.0.1 http://www.facebook.com
or other sites. Save and restart your PC.

- If he is using some sort of proxy you need to configure proxy server.

- Try Web proxy .. http://www.vpnbook.com/webproxy ! Open and put site you want to browse !

If nothing works

- AT LAST IF NOTHING WORKS .. Go to http://www.pdproxy.com , download there client and register a trial account. Open software select protocol as UDP , put user name and password and press connect
- wait for connection to get established ! After successfully connection try to open blocked sites.
