Uninstalling the application

Uninstalling the Kaspersky Embedded Systems Security involves the following steps:

1. Uninstalling the application and graphical user interface of the application

   Uninstall the packages of the application and, if you are using the graphical user interface, the packages of the graphical user interface from the protected devices.

   You can uninstall both the application package and the graphical user interface package, or uninstall only the graphical user interface package. It is not possible to uninstall only the application package if the graphical user interface package is installed.

   You can uninstall the application and the application's graphical user interface in the following ways:

   • Remotely using Kaspersky Security Center.
   • Locally from the command line.

   While the application is being uninstalled, all Kaspersky Embedded Systems Security tasks will be stopped on the device.

2. Removing Network Agent

   If you were using Kaspersky Security Center to manage Kaspersky Embedded Systems Security, you must uninstall the Network Agent from protected devices.

   You can uninstall Network Agent in the following ways:

   • Remotely using Kaspersky Security Center.
   • Locally from the command line.
3. Installing the Kaspersky Embedded Systems Security management plug-in

   If you were using Kaspersky Security Center to manage Kaspersky Embedded Systems Security, you must uninstall the Kaspersky Embedded Systems Security administration web plug-in or MMC plug-in, depending on the console that you were using to manage Kaspersky Security Center.

After removing the application, all information saved by the application is deleted, except for the license database. Installed application certificates are also removed. The license database is saved, and you can use it to reinstall the application.

If the application was installed in a systemd, the systemd settings are restored to their initial state after the application uninstallation.

Uninstalling the application and Network Agent using Kaspersky Security Center

You can remotely uninstall Kaspersky Embedded Systems Security and Network Agent from the client devices.

Uninstallation is performed using the remote uninstallation of applications task in Kaspersky Security Center Web Console or in the Administration Console. For more details, refer to the Kaspersky Security Center Help system.

If you want to remove only the graphical user interface without removing the application, specify the USE_GUI=No setting value in the autoinstall.ini configuration file and start the remote application installation task.

Uninstallation is performed in the background. After the application uninstallation finishes, you will be prompted to restart the client device.
