Updating to this Release
The AV Defender update can be scheduled at an appropriate time by adding a maintenance window to your devices. Updating involves an incremental update of components or modules without the need to remove protection. The device will be rebooted after the update if the maintenance window allows AV Defender Reboots. A reboot may be required based on Installation Status. If you do not want updates or reboots to proceed automatically, you can disable them by removing the appropriate maintenance windows from the device or rule.
