A firewall protects your computer from being spied on. It checks which data and programs from the Internet or network reach your computer and which data is sent from your computer. As soon as there is an indication that data is to be installed or downloaded on your computer without authorisation, the firewall alarm sounds and blocks the unauthorised data exchange.

If you click on the Firewall header, a choice of actions that can be carried out directly from here is displayed.

Open firewall: You can use this function to open the G Data firewall in a new window where you carry out a detailed configuration. However, in normal operation this is not required. All basic settings can be controlled via the SecurityCenter interface.


Disable autopilot: It is generally advisable to use the firewall in autopilot mode. It then virtually runs in the background and protects you without you having to undertake major settings.

If you are using the firewall without the autopilot, a dialogue window will appear in the event of doubt in which you can gradually optimise the firewall for your system environment. This is a helpful feature for experienced users. Disabling the autopilot is not normally necessary.

Disable firewall: You can also disable the firewall if required. Your computer will still be connected to the Internet and other networks, but the firewall will no longer protect it from hackers or electronic espionage.

Settings: You can use this button to access basic settings options if necessary. Please read about this in the section entitled: Settings – Firewall
