Handling MAV-BD Reboots

  • Reboots can be automatically enabled for the upgrade process by selecting an option in the MAV policy under the “Installation Settings” tab. Automatic reboots occur within 5 minutes of taking the update. Please ensure this option is disabled if you do not want your end user machine to automatically reboot. If the automatic reboot option is not enabled, the reboot will be displayed as a blue dot within the North Pane of the RMM Dashboard, indicating that the machine needs a reboot to complete the installation.  Reboot the machine at your earliest convenience.reboot delay image 

    Determining the version on a device:

    The version of the MAV agent, as well as the MAV engine version, can be seen in 2 places – by looking at the Managed Antivirus Check (Bitdefender), or by running the Managed Antivirus Protection Report.
