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.

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.

To see the version of the agent within the MAV check, navigate to the South Pane of the device and find the Managed Antivirus Check – Bitdefender and select the “More Information” link.  To see across devices, run the Managed Antivirus Protection Report under Reports > Managed Antivirus > Antivirus Protection Report. Ensure that the Agent Version and Engine Version columns are selected from the Column drop down.
