This document will detail the recommended practice for configuring a 3rd party antivirus solution to update properly when Deep Freeze is protecting a workstation.
Deep Freeze provides administrators with a way to protect workstations from changes by rolling back any change made to the computer at reboot. Deep Freeze does not make any distinction between changes that are malicious, or changes that are desired on a workstation and this can pose some challenges in managing 3rd party products that require updates to occur on a periodic basis.
The most common interaction that we find on customers workstations is between antivirus software and Deep Freeze. Antivirus software by design requires periodic updates to maintain it’s effectiveness on a client workstation, and problems may arise unless steps are taken to ensure that the antivirus software can perform updates in a timely manner.
Scheduled are used to configure the antivirus software to update in a timeframe where Deep Freeze will not be protecting the workstations. 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.
Configuring Trend Micro Business Security to update with Deep Freeze
Trend Micro's Business Security supports the use of a command line function that can be used to trigger antivirus updates when the workstations enter into maintenance mode. To configure Deep Freeze to trigger Trend Micro to update when maintenance mode starts follow the process below:
Deep Freeze 7.5 or Higher1. Open the Deep Freeze Configuration Administrator.

7. The options “Allow User to Cancel Event”, “Shutdown after Maintenance”, and “Disable Keyboard and Mouse” can be enabled if desired.
8. Click on the Batch File tab.
9. Enter the following in the Batch File Contents field on the tab:
@ECHO OFF IF EXIST "C:\Program Files\Trend Micro\Security Agent\pccntmon.exe" "C:\Program Files\Trend Micro\Security Agent\pccntmon.exe" -u
IF EXIST "C:\Program Files (x86)\Trend Micro\Security Agent\pccntmon.exe" "C:\Program Files (x86)\Trend Micro\Security Agent\pccntmon.exe" -u 10. Click on the “Create” button on the toolbar and save the Workstation Install Program in a location that you will remember.
