Example

Anti-Virus programs require regular virus definition updates to protect the system. Virus definitions can be updated during a Thawed Period.

In the above screen, a Thawed Period task has been created daily between 12:00 AM and 12:15 AM. The user is not allowed to cancel the task before it starts. The computer will shut down after the maintenance period. The keyboard and mouse are disabled during the maintenance period. The task is configured to display a message to the user 5 minutes before the task starts. The following message will be displayed on the computer at 11:55 AM The computer will reboot in 5 minutes to enter into a Thawed Period.

To ensure that the virus definitions are applied permanently, schedule the virus definition update for your Anti-Virus program so that it starts after Deep Freeze successfully starts the Thawed Period task and ends before Deep Freeze ends the Thawed Period task. This ensures that the virus definitions downloaded and updated by the Anti-Virus program stay permanently on the system. Hence the system is fully protected by Anti-Virus and Deep Freeze.

Faronics Anti-Virus: Faronics Anti-Virus works with Deep Freeze and does not require a Thawed Period task for updating virus definitions. Faronics Anti-Virus can update virus definitions even when the computers managed by Deep Freeze are in a Frozen state. Other Anti-Virus Programs: All other Anti-Virus programs require scheduling a Thawed Period task to update virus definitions. Refer to your Anti-Virus program user guide for information on how the virus definitions are downloaded. Alternatively, virus definitions can be applied manually when the computers managed by Deep Freeze are in a Thawed state. You can also schedule a no user intervention install of your virus definitions through a Batch File Task.
