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 the Windows firewall, which monitors data traffic coming into your computer. With both the Webroot and Windows firewall turned on, your data has complete inbound and outbound protection.
You should not turn off either the Windows firewall or the Webroot firewall. If they are disabled, your system is completely open to many types of threats whenever you connect to the Internet or to 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.
The Webroot firewall is preconfigured 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 where you can block the traffic or allow it to proceed.
We recommend that you keep the firewall enabled. However, you can disable it by clicking PC Security and the Firewall tab. Click the green button to turn it off. (A green button indicates the shield is on; a gray button indicates the shield is off.)
If you would like to change the firewall options, see the following topics:
