To configure Deep Freeze to trigger AVG to update when maintenance mode starts follow the process below: Deep Freeze 7.5 or Higher 1.
Select Maintenance in the Event Type drop down dialog and click Add. Name the event “AVG Antivirus” in the Event Name field. Select the frequency for the updates to occur in the Day drop down and set the start and end time for the event.
This has the advantage of being one of the less difficult methods to configure but does require that the workstations have a period of time where they will not be used and can be configured to update automatically.
