Internet Connection Firewall
NOTE: Enabling the Internet Connection Firewall does not reduce the need for virus-checking
software.
The Internet Connection Firewall provides basic protection from unauthorized access to the computer when
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 portion of the Control Panel. For more information, see Windows
Help and Support Center.
