Configuring Trend Micro Business Security to update during Deep Freeze Maintenance

Overview

This document will detail the recommended practice for configuring a 3^rd party antivirus solution to update properly when Deep Freeze is protecting a workstation.

Introduction

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 3^rd 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:
