Summary

Virtual Desktop Infrastructure (VDI) is a server computing model that enables desktop virtualization and covers the hardware and software systems required to support a virtualized environment.

This article discusses the best practices when using the Apex One/OfficeScan client in a VDI environment.

Follow these best practices to mitigate performance issues when running the Apex One/OfficeScan client on a VDI environment:

  1. Use Trend Micro Virtual Support, which is available as a plug-in. This feature prohibits clients from performing on-demand/scheduled scan or component updates simultaneously, optimizing I/O on virtual hosts.

    Virtual Desktop Support

    Create golden images for Apex One/OfficeScan client installation after installing the Virtual Desktop Support on the Apex One/OfficeScan server. Refer to this article: Configuring the Apex One/OfficeScan Virtual Desktop Infrastructure (VDI) client.

  2. Adjust the maximum number of Apex One/OfficeScan clients for simultaneous on-demand/scheduled scan or component updates. Follow this article: Controlling the performance of the Virtual Desktop Infrastructure (VDI) environment.
  3. These services can affect overall performance. It is advised to disable them:
    • Disable Unauthorized Change Prevention Service:
      • Behavior Monitoring
      • Device Control
      • Client Self Protection
    • Disable Firewall Service.

      Service Settings

    • Disable Suspicious Object Synchronization.
  4. Upgrade Apex One/OfficeScan to the latest version.

    It enhances client management on non-persistent desktops, prohibiting duplicated clients from appearing on the client management tree.

    Virtual Desktop Support enhances the performance of smart scan component updates on a VDI environment.

  5. Select Smart Scan as Scan Method. Smart Scan update performance on a VDI environment has been enhanced on these versions.

  6. Disable digital signature cache and enable on-demand cache.

    Enabling both of them can affect performance on a VDI environment.

    Privileges and Other Settings

  7. Disable Scheduled Scan if Virtual Desktop Support is not used.

    Simultaneous scanning on several guest OS will lead to a performance drop on the host machine.

  8. Avoid changing the Apex One/OfficeScan settings on a root domain or domains with multiple clients.

    For example, do not switch between Conventional Scan and Smart Scan on a VDI environment at those domains.

    A scan type change will immediately trigger a full pattern update on a guest environment, causing disk I/O congestion.

  9. Recreate the golden/master VM image with the latest Apex One/OfficeScan pattern components when deploying non-persistent desktops within 14 days after creating the image.

    Apex One/OfficeScan clients won't be able to update incremental components, affecting performance on virtual hosts.
