5. Known Issues

Windows Security Agent Known Issues

Security Agent Deployment and Upgrade

  1. When the following conditions apply, the proxy server information needs to be added to the firewall exception list in the Worry-Free Business Security Services web console.

  2. The WFBS-SVC_Downloader.exe file can only be run on the endpoint on which the user downloads the file. If a user copies the file to another endpoint and runs the file there, an error occurs.

  3. Endpoints may lose network connection temporarily during installation.

  4. Users cannot deploy the Security Agent program when Internet Explorer 10 or later is running in Metro mode on Windows 8 or later.

  5. Security Agents running on Windows 7, 8, or 8.1 endpoints will be uninstalled when users upgrade an endpoint to Windows 10. Users must upgrade Security Agents to Worry-Free Business Security Services 5.7 Service Pack 1 before upgrading to Windows 10. After Windows 10 is successfully installed, a toast notification will appear to initiate the Security Agent reinstallation on the new operating system.

  6. The email installation link does not work properly when users try to re-activate the Security Agent using Microsoft Edge. However, Microsoft intends to resolve this issue in a later release.

Security Agent

  1. If the Security Agent is enabled and a malware program resides in the Security Agent folder before Real-time Scan starts, the Security Agent cannot restrict that malware from updating the registry.

  2. On Windows 10 endpoints, Worry-Free Business Security Services alerts may be hidden behind the Microsoft Edge browser window. Users must check for any unauthorized event or threat alerts that may appear.

  3. If the Security Agent is installed on a Windows endpoint running Enhanced Mitigation Experience Toolkit (EMET), there might be some performance and conflict issues. Trend Micro recommends not installing the Security Agent and Microsoft EMET on the same endpoint.


  1. During Security Agent installation or firewall driver uninstallation, the endpoint may temporarily lose its network connection. Some applications, such as Secure Shell (SSH), Terminal Services Client, or Remote Desktop could be affected by the disconnection. If the network connection is lost, restart the application after installing the Security Agent or after disabling the firewall.

  2. The Security Agent firewall may 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 VMware client registry:

  4. The firewall does not support IPv6.

Web Reputation and URL Filtering

  1. When running Internet Explorer 9 or later with Internet Explorer Enhanced Security Configuration, the Web Reputation plug-in module (TmIEPlugInBHO Class) cannot be automatically applied. Risky URLs using SSL cannot be blocked.

  2. Web Reputation Services and URL Filtering are not supported when Internet Explorer 10 or later is running in Metro mode on Windows 8 or later.

  3. The Microsoft Edge browser does not currently support Worry-Free Business Security Services plugins for Web Reputation and URL Filtering. These plugins enable blocking of websites when using the HTTPS protocol.

Windows Small Business Server Dashboard Add-In Tool

  1. When Internet Explorer 9 is installed under Windows Small Business Server 2011 Essentials, a popup window concerning unused windows appears when closing the Dashboard console.

  2. Dashboard Add-in is not compatible with Internet Explorer Enhanced Security Configuration. Ensure this option is disabled before opening the Dashboard.

Login Script Setup Tool

  1. Endpoints installed on Windows Vista or later and have User Account Control (UAC) enabled cannot run automatic installation.

Device Control

  1. Multiple log entries appear when a user tries to access or copy files to a USB device. Device Control detects each instance as a single policy violation but includes multiple entries in the logs to differentiate the OS versions.

  2. Device Control supports all 32-bit operating systems and only the following 64-bit platforms: Windows Vista SP1 x64 and later.

Mac Security Agent Known Issues

  1. The Security Agent does not support root accounts.

  2. When the operating system is upgraded to Mac OS X 10.8, the Security Agent program cannot start. The Security Agent requires Java and the upgrade to Mac OS X 10.8 automatically removes Java. To resolve this issue, install the latest version of Java and then restart the Mac.

  3. When installing the Security Agent on a Mac running on Mac OS X 10.6.7 or earlier, the installation process may be unsuccessful. To resolve this issue, upgrade to Mac OS X 10.6.8, and then download and install the following Apple update:

Android Security Agent Known Issues

  1. When Worry-Free Business Security Services is installed on a device running Android 2.x, the system proxy is not updated as this version of the operating system does not support system proxies. This could also prevent the device from connecting to the server to receive updates.

  2. Worry-Free Business Security Services cannot be installed on rooted Android devices.

  3. On an Android device, if the user goes to Settings > Apps > Worry-Free Security > Storage and taps CLEAR CACHE, the Security Agent might not be able to connect to the server to receive updates. The user would need to re-enroll the device.

  4. If other installed apps interfere with the device's network connection, the Security Agent might not be able to connect to the server to receive updates.

  5. When using the "Remote Locate" feature to find a mobile device, the language code (for example: en, jp, fr) that displays in the browser for the embedded Google Maps may not be the same as the language used by the web console.

  6. Worry-Free Business Security Services uses Google Cloud Messaging (GCM) for Android mobile device management commands. Commands sent to Android devices can take some time to be received, or the commands may be unsuccessful.

  7. If multiple device administrators manage a single Android device, some commands may not be successful (for example: reset password). Worry-Free Business Security Services uses the Android Device Administrator for mobile device management commands. When more than one Device Administrator exists for the same Android device, the stricter policy on the device has priority. For example, if two apps both require users to follow a password policy, only the stricter policy is applied.

iOS Security Profile Known Issues

  1. Worry-Free Business Security Services uses the Apple Push Notification service (APNs) for iOS mobile device management commands. Commands sent to iOS devices can take some time to be received, or the commands may be unsuccessful.

  2. If the Private Browsing feature in Safari is enabled (, iOS devices may not successfully complete device enrollment.
