Kerio Personal Firewall provides automatic checks for new versions. These versions, if detected, can be downloaded. Automatic checks are provided after each start of Personal Firewall Engine and then every 24 hours.

Checks for new versions can be also run by hand using the Check now button in the Overview / Preferences section of the Kerio Personal Firewall configuration dialog (for details see chapter 6.3. Preferences).

If you already have the latest version of Kerio Personal Firewall, the connection with the server is closed and the next check is scheduled. If a new version is detected, information on this version and its download is provided.

Click on the Next button to start download of the new version and to run the installation program. Kerio Personal Firewall always checks signature of a downloaded file — this feature ensures that any downloaded file will be original (it is not attacked by a virus, damaged, etc.).

The system must be restarted after a new version is installed.

The download or the installation process can be stopped by the Cancel button. If the process is canceled, the update will not be offered again automatically, however, it can be run by hand whenever needed. When a new version is found, Kerio Personal Firewall will open the update dialog automatically.

For detailed information on the Kerio Personal Firewall installation refer to chapter 2.1. Installation, Upgrade and Uninstallation.

Note: Kerio Personal Firewall follows special internal rules which always allow access to the server where the product can be updated and registered. Therefore, the automatic update checks cannot be blocked by inappropriate firewall settings.
