4. System Requirements

Visit the following website for a complete list of installation and upgrade requirements:

5. Installation

The WFBS administrator in your organization is responsible for installing and upgrading the Security Agent. Contact the administrator if you have questions or concerns about the installation or upgrade.

6. Post-installation Configuration

The WFBS administrator will contact you if post-installation steps are required.

7. Known Issues

Some product features do not support certain operating systems and associated applications. For details, see Available Security Agent Features in the Online Help.

The following are the known issues in this release:

Security Agent Deployment, Upgrade, and Usage

Note: For details about installation limitations on certain operating systems, see Security Agent Installation Methods in the Online Help.

  1. To completely reinstall or upgrade the Security Agent, you will need to restart the computer. A restart will also be necessary when updating some components.

  2. WFBS supports Remote Desktop, Remote Web Workplace, and Citrix server terminal applications.

    In a Terminal Services environment, administrators can decide whether to show or hide the Security Agent icon in the Windows task bar. This setting applies to all or none of the active user sessions. It is not possible to apply the setting to individual user sessions.

    If the icon shows on all active user sessions, memory usage may increase. To prevent this issue from occurring:

    a. On the Security Agent host, open the registry.

  3. b. Create/modify the following REG name/value pair:


    For 32-bit: HKLMSOFTWARETrendMicroPCcillinNTCorpCurrentVersionMisc.

    For 64-bit: HKLMSOFTWAREWow6432NodeTrendMicroPCcillinNTCorpCurrentVersionMisc.

    Name: RCS

    Type: DWORD

    Value: 202 (in decimal format)

    There will be no PccNTMon instances created when its value is set to 202.

  4. The manual scan process bar is not fully synchronized to the Files Scanned count based scan mechanism.

  5. Security Agents running on Windows Server 2019 cannot report security statuses to Windows Security Center because Windows Server 2019 does not provide the Windows Security Center service. If Windows Defender is enabled on Windows Server 2019 with the Security Agent installed, performance issues may occur. Trend Micro recommends disabling Windows Defender before installing the Security Agent.

Web Reputation/URL Filtering

  1. Browser Exploit Prevention supports Internet Explorer versions 9, 10, and 11.
  2. In an unstable network environment, the Trend Micro Web Reputation server may pass a website without filtering.
  3. If proxy settings are configured on Windows 10, HTTPS Web Threat Protection cannot work on Microsoft Edge.


  1. When uninstalling the firewall driver, the agent could temporarily lose the network connection. Some applications (such as Secure Shell (SSH), Terminal Services Client, or Remote Desktop) could be affected by the disconnection. If this occurs, restart the application after disabling the firewall. Note that restarting also completes the uninstallation process.

  2. The Security Agent firewall might conflict with other firewall applications. Trend Micro recommends uninstalling or disabling other firewall applications.

  3. On VMware clients, the Security Agent firewall may block all incoming packets. To address this issue, add the following value to the client's registry:

    Key: HKEY_LOCAL_MACHINESOFTWARETrendMicroPC-cillinNTCorpCurrentVersionPFW
    Name: EnableBypassRule
    Type: REG_DWORD
    Value =1
    1 means enable, 0 means disable
