The Webroot firewall monitors data traffic traveling out of your computer ports. It looks for untrusted processes that try to connect to the Internet and steal your personal information. It works with another firewall, like the Windows firewall, which monitors data traffic coming into your computer. With both the Webroot and another firewall turned on, your data has complete inbound and outbound protection.

You should not turn off either the Webroot firewall or the other firewall you are using. If they are disabled, your system is left open to many types of threats whenever it is connected to the Internet or a network. These firewalls can block malware, hacking attempts, and other online threats before they can cause damage to your system or compromise your security.  Using the Webroot SecureAnywhere firewall in conjunction with another firewall will not affect your system performance.

The Webroot firewall is pre-configured to filter traffic on your computer. It works in the background without disrupting your normal activities. If the firewall detects any unrecognized traffic, it opens an alert for you to block or allow traffic as desired.

We highly recommend you keep the firewall enabled. If you want to disable it, however, you can do so by clicking the gear icon next to PC Security, and then find the firewall listing down the right column. Click the green button to turn it off. (A green button indicates the shield is on; a red button indicates the shield is off.)
