7. Known Issues

Some product features do not support certain operating systems and associated applications. For details, visit


The following are the known issues in this release:

7.1 Security Agent Deployment, Upgrade, and Usage

Note: For details about installation limitations on certain operating systems, see the Help topic:


  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, including the firewall and the proxy drivers.

  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: HKLM\SOFTWARE\TrendMicro\PCcillinNTCorp\CurrentVersion\Misc.

    For 64-bit: HKLM\SOFTWARE\Wow6432Node\TrendMicro\PCcillinNTCorp\CurrentVersion\Misc.

    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 Files Scanned count based scan mechanism.

7.2 Behavior Monitoring/Device Control

  1. Behavior Monitoring and Device Control fully support 32-bit operating systems. On 64-bit operating systems, only Vista x64 SP1 and later are supported.

7.3 Web Reputation/URL Filtering

  1. Browser Exploit Prevention supports Internet Explorer versions 6, 7, 8, 9, 10, and 11.

  2. In an unstable network environment, the Trend Micro Web Reputation server may pass a website without filtering.

7.4 Firewall

  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 (which 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_MACHINE\SOFTWARE\TrendMicro\PC-cillinNTCorp\CurrentVersion\PFW
    Name: EnableBypassRule
    Type: REG_DWORD
    Value =1
    1 means enable, 0 means disable
