Windows Firewall
The Windows Firewall provides basic protection from unauthorized access to the computer while the
computer is connected to the Internet. The firewall is automatically enabled when you run the Network
Setup Wizard. When the firewall is enabled for a network connection, the firewall icon appears with a
red background in the Network Connections section of the Control Panel.
Note that enabling the Windows Firewall does not reduce the need for virus-checking software.
For more information, see the Help and Support Center for the Microsoft
