Note: Only one Personal Firewall should be installed to your system. This also includes the Firewall on Internet Security Suites. Always uninstall one before installing another. System Reboots required. Windows default Firewall should always be disabled when using a Personal Firewall software. Installing more than one Personal firewall could very much corrupt your Internet connection, cause very slow speeds or even corrupt Windows in general.
