Windows Firewall. Windows Firewall is a Microsoft Windows application that filters information coming to your system from the Internet and blocking potentially harmful programs. The software blocks most programs from communicating through the firewall.
TO ACCESS FIREWALL
Open the Control Panel.
Open the Windows Firewall window. In Windows 7, choose System and Security and then choose Windows Firewall. In Windows Vista, choose Security and then choose Windows Firewall. In Windows XP, open the Windows Firewall icon.

i hope it helps you..
