Firewall: Windows: Turn On
In addition to antivirus software, everyone should run a firewall. A firewall monitors network traffic into and out of your system and attempts to block connections that appear to be hostile.
CIT recommends using the Firewall built into the Windows XP, Vista, and Macintosh operating systems.
See the About the Windows Firewall page for more information about the capabilities of the Windows firewall and the firewall included with Symantec Endpoint Protection.
