1. About OfficeScan

Trend Micro™ OfficeScan™ protects enterprise networks from malware, network viruses, web-based threats, spyware, and mixed threat attacks. An integrated solution, OfficeScan consists of an agent program that resides at the endpoint and a server program that manages all agents. The agent guards the endpoint and reports its security status to the server. The server, through the web-based management console, makes it easy to set coordinated security policies and deploy updates to every agent.

OfficeScan is powered by the Trend Micro™ Smart Protection Network™, a next generation cloud-client infrastructure that delivers security that is smarter than conventional approaches. Unique in-the-cloud technology and a lighter-weight agent reduce reliance on conventional pattern downloads and eliminate the delays commonly associated with desktop updates. Businesses benefit from increased network bandwidth, reduced processing power, and associated cost savings. Users get immediate access to the latest protection wherever they connect—within the company network, from home, or on the go.

    To resolve this issue:

    1. Remove the current PHP version. Go to Control Panel > Add/Remove Programs.
    2. Run the OfficeScan 11.0 setup program.

    For detailed steps, see

  11. After upgrading to OfficeScan 11.0 SP1, Windows Control Panel still displays the OfficeScan 11.0 server version. Check the OfficeScan web console for the actual server version.

  12. The web console Dashboard displays a "500 Internal Server Error" if Microsoft Visual C++ 2008 Redistributable Package (x86) is not installed. To resolve this issue, install Microsoft Visual C++ 2008 Redistributable Package (x86) and restart the Apache or IIS service.

  13. If the OfficeScan server computer or an agent endpoint has not properly updated its root certificate(for example, the computer does not have an Internet connection), OfficeScan cannot verify the computer's digital signatures during Inter-Process Communication (IPC). To solve this issue, you must manually update the root certificate or perform a Windows Update.

SQL Database Migrations

  1. When transferring the OfficeScan database to a SQL database installed on a Domain Controller endpoint, you must select the “Migrate the OfficeScan database to an existing SQL Server” option on the SQL Migration Tool (SQLTool.exe).

  2. If you want to install a new SQL Server 2008 R2 SP2 Express on a Domain Controller endpoint, you must follow the Microsoft Knowledge Base information on how to install SQL Server 2008 R2 SP2 Express manually.

Agent Installation, Upgrade, and Uninstallation

  1. The OfficeScan agent is unable to query the Web Reputation servers after performing a fresh installation or upgrade. To resolve the issue, ensure that agents restart their endpoints if a restart notification appears.

  2. If you create a login script in Active Directory and then log on as administrator on an endpoint running Windows Vista Home, Server 2008, 7, 8, or Server 2012, the OfficeScan agent cannot be installed to the endpoint and the message that displays states that the account used is not an administrator account.

  3. When this product version is installed to a Citrix Presentation server, the Citrix client loses connection with the server. To address this issue:

    1. On the Citrix server, open Registry Editor and navigate to HKLM\SOFTWARE\TrendMicro\NSC\TmProxy\WhiteList.
    2. Click Edit > New > Key and name the key IIS.
    3. Under this new key, create a string value (Edit > New > String Value) with the name ProcessImageName and use w3wp.exe as its value.
    4. Restart the OfficeScan NT Listener service.
  4. When an application that locks the Windows Service Control Manager (SCM) is launched, the OfficeScan agent cannot be installed or upgraded. Before upgrading or installing OfficeScan, ensure that no SCM-locking application is running.
  5. When running Vulnerability Scanner on an endpoint running Windows Server 2008, Windows 7, Windows 8, or Windows Server 2012, the DHCP tab does not display on the tool's console.
  6. The ServerProtect Normal Server Migration tool is unable to:

    To resolve these issues, open Registry Editor on the Normal Server and Information Server and add following registry key:

  7. Microsoft IIS 7 does not work when:

  8. A message displays on the endpoint using Windows Server 2008 without Service Pack 2, instructing the user to restart the IIS service to resolve the issue.

  9. To perform agent web installation on endpoints with a 64-bit processor architecture, you must use the 32-bit version of Internet Explorer. The 64-bit version of Internet Explorer is not supported.
  10. The OfficeScan agent may not install correctly if Norton SystemWorks™ antivirus is installed on the endpoint. Uninstall it before installing OfficeScan agent.
  11. If the OfficeScan agent is installed using the "per-user" method, the OfficeScan agent shortcut will still show on all the users' Windows Start menu.
  12. After upgrading OfficeScan, the following issues occur:

    To resolve these issues, perform the following steps:

    1. Stop the Cryptographic Services from the Microsoft Management Console.
    2. Navigate to C:\Windows\system32 and rename the "catroot2" folder to "oldcatroot2".
    3. Start the Cryptographic Services.
    4. Open a command prompt (cmd.exe) and run the following commands:

      regsvr32 wintrust.dll

      regsvr32 netcfgx.dll

    5. Restart the endpoint.
  13. The OfficeScan agent unloads and then reloads three times when upgraded to this version. This happens if the agent upgrades, applies smart scan as its scan method, and then applies the domain level scan method.
  14. After an OfficeScan agent in a VPN environment is uninstalled successfully, the agent is not removed on the web console's agent tree and its status is offline.
  15. The administrator will not be able to remotely install OfficeScan agent to Windows 7 x86 platforms without enabling the default administrator account. To resolve this issue:

    Note: Enable the Remote Registry service on the Windows 7 machine. By default, Windows 7 machines disable this feature.

    Option A: Use the domain administrator account to remotely install OfficeScan 10.5 clients to Windows 7 machines.

    Option B: Use the default administrator account:

    1. Type the "net user administrator /active:yes" command from the command console to enable the default administrator account.
    2. Use the default administrator account to remotely install the OfficeScan agent to the Windows 7 machine.
  16. Installing OfficeScan agents to Windows 7 or Windows Server 2008 R2 using a GUEST OS running on VMware Workstation 6.x and below may cause the system to stop responding. This is because of compatibility issues with the Intel™ Network Adapter Driver.
  17. When installing the OfficeScan agent on Windows 8 and Windows Server 2012 platforms using the browser-based installation method, the installation is unsuccessful if the user is currently in Windows UI mode. This is due to Internet Explorer 10 not allowing ActiveX controls to run.

    To resolve this issue:

    Switch to desktop mode on Windows 8 and Windows Server 2012 platforms while performing a browser-based installation of the OfficeScan agent.

  18. When running Internet Explorer or Microsoft PowerPoint on Windows Vista platforms, restart notifications appear in the foreground.

  19. Upgrade may fail if using an MSI package to upgrade an OfficeScan agent that was originally installed also using an MSI package. Perform the following steps:

    1. Ensure that the new MSI package has the same file name as the original package. If you do not know the file name of the original MSI package, check the following registry key: HKEY_CLASSES_ROOT\Installer\Products\F4D73DF48B1EA594592F1CD021C5A1C9\SourceList\PackageName
    2. Install the new MSI package. Use command prompt to execute the package with the parameter "/fvo". For example, msiexec /fvo c:\temp\package.msi.
  20. If you add the OfficeScan agent program to the Microsoft Software Restriction Policy list using the user interface, you may need to restart the endpoint before subsequent additions to the list take effect.
  21. After rolling back a component on an OfficeScan agent, the Component Update Details screen displays "n/a" under the Notification Sent and Notification Received columns.


  1. A Microsoft Hyper-V virtual machine might not be able to start if the host endpoint has OfficeScan agent installed. This is because the OfficeScan agent and Hyper-V virtual machine access the same Hyper-V xml file, which causes file access violation. As a workaround:

  2. When specifying the scan target for Scheduled Scan, Scan Now and Real-time Scan, spyware/grayware scan can be disabled. However, for Manual Scan, there is no option for disabling spyware/grayware scan, which means that during Manual Scan, OfficeScan will always scan for spyware/grayware.
  3. When OfficeScan is configured to scan mapped drives during Manual Scan, the mapped drive may not get scanned when scanning is initiated through Terminal Service client.
  4. When an email containing an attachment with spyware/grayware is retrieved through Eudora email client and POP3 Mail Scan is disabled, OfficeScan's Real-time Scan denies access to the email even if the scan action is "clean". The email does not appear on the inbox and the Eudora client displays a message informing the user that access to the email is denied.
  5. In a Citrix environment, when the OfficeScan agent detects a security risk during a particular user session, the notification message for the security risk displays on all active user sessions.

    Security risk can be any of the following:

  6. The deferred scan feature is not available if the Virus Scan Engine (VSAPI) has not been upgraded to version 9.713 or later.

Server Update

  1. When updating OfficeScan patterns and engines from Control Manager, administrators are not notified of the update status even if notifications are enabled. The update status can be viewed from the Control Manager console.

Agent Update

  1. OfficeScan agents with agent-level settings can only download settings from the OfficeScan server, not Update Agents.
  2. An Update Agent running a 64-bit platform is unable to generate incremental patterns. Therefore, the Update Agent always downloads all incremental patterns available in the ActiveUpdate server, regardless of how many of these patterns it has previously downloaded.
  3. When the OfficeScan server notifies agents to update components, agents that obtain updates from an Update Agent will not be able to update if the Update Agent has not been upgraded to version 10.0 SP1 or higher. However, these agents can still obtain the updates directly from the OfficeScan server.
  4. When the server and agent endpoints are located on geographical locations with different time zones, the agent cannot be configured to update based on the server's time zone.

Server Management

  1. The Active Directory scope may display as empty or redirect to the Active Directory integration screen when querying Outside Server Management reports with a broad scope. Ensure that the first task is finished before performing another query.
  2. The User Role has access and configure permissions on the agent Manual Update page but only for selected domains. However, all agents receive the notification when this role clicks Initiate Update.
  3. For Menu Items for Managed Domains, when an Active Directory user is part of several Active Directory groups, the user combines domain permissions but applies the higher role setting on all applicable domains.
  4. When the endpoint's date/time format is changed, the date/time format on the OfficeScan console does not automatically change.
  5. When the web console is opened in Internet Explorer 9 or later, a certificate error displays.
  6. Users are unable to collapse the agent management tree menu items on the User Account - Step 3 Define Agent Tree Menu screen when configuring User Accounts on Windows 8.1 and Windows Server 2012 R2 platforms running Internet Explorer 11. To resolve this issue:

    Install the Internet Explorer 11 hotfix from the Microsoft Windows Update site:

  7. After expanding the menu items when creating or modifying a User Role or User Account, you cannot collapse the the menu items again in Internet Explorer 11.

  8. The OfficeScan server logon account passwords are not encrypted using AES 256 encryption, even after enabling the feature.

Agent Management

  1. Agent names in the OfficeScan agent tree supports only 15 characters and truncates the succeeding characters.
  2. Double-byte characters (characters typically used in East Asian languages) cannot be used when specifying the notification message for virus/malware infection source (Administration > Notifications > Agents > Virus/Malware tab).
  3. If the agent security level configured on the web console is set to "High", connection through Nortel VPN client cannot be established.
  4. Select the Show icon and notifications option to display the OfficeScan icon in the Windows 7 and 8 system tray. The default option for Windows 7 and 8 is Only show notification.
  5. Some agent console screens include a Help button, which, when clicked, opens context-sensitive, HTML-based Help. Because Windows Server Core 2008 lacks a browser, the Help will not be available to the user. To view the Help, the user must install a browser.
  6. On the web console's Update Summary screen (Updates > Summary), the Behavior Monitoring Configuration Pattern, Policy Enforcement Pattern, and Digital Signature Pattern do not appear correctly due to JavaScript caching. To resolve this issue:

    Clear the browser cache to update the component names.

  7. The Prompt users before executing newly encountered programs downloaded through HTTP or email applications (Server platforms excluded) feature only monitors ports 80, 81, and 8080 on Windows platforms (except Windows 8 which monitors all ports).

Device Control

  1. If the Device Control permission for USB storage devices is changed from "Allow" to "Block" when USB storage device files are already opened on the agent endpoint, access to the opened files is still permitted. The Block permission is updated the next time that the USB device is plugged in, or the agent endpoint is restarted.
  2. Device management applications (such as iTunes, HTCSync, and SamSung Kies) for devices blocked by Device Control are also blocked from user access.
  3. The Device Control Exception list is not supported on Windows XP platforms.

Data Loss Prevention

  1. Data transmitted through Instant Messaging applications are not detected if the applications use a non-transparent proxy server.
  2. After upgrading the OfficeScan agent to OfficeScan 11.0 from an OfficeScan version prior to 10.6 SP3, the preexisting agent-side Data Loss Prevention logs are deleted (unless updating from the OfficeScan 10.6 SP2 DLP Enhancement Patch).
  3. Data Loss Prevention logs can only display the first 1000 bytes of characters in the Source and Destination columns due to a buffer overflow issue with long file names.

OfficeScan Firewall

  1. The Firewall rule for outgoing traffic will not work as expected if a machine has several IP addresses with different Firewall policies.
  2. When the security level on a Citrix server is medium or high, perform the following steps:

    1. On the OfficeScan server web console, create a new firewall policy.
    2. Add the following port numbers to the policy's exclusion list: 1494, 2598
    3. Go to Agents > Firewall > Profiles and click Assign Profile to Agents.
  3. For Windows XP and Windows Server 2003 platforms hosting VMware agents, incoming packets to a VMware agent endpoint are dropped if the host machine has the OfficeScan agent installed.

    Workaround (for all agents):

    1. On the server computer, open ofcscan.ini under the \PCCSRV folder.

    2. Add the following setting under [Global Setting]: EnableGlobalPfwBypassRule=1

    3. On the web console, go to Agents > Global Agent Settings and click Save to deploy the setting to all agents.

    Workaround (for specific agents):

    1. On the agent endpoint, open Registry Editor.
    2. Add the following registry value:

      • Key: HKEY_LOCAL_MACHINE\SOFTWARE\TrendMicro\PC-cillinNTCorp\CurrentVersion\PFW

        For x64 endpoints: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432\TrendMicro\PC-cillinNTCorp\CurrentVersion\PFW

      • Name: EnableBypassRule
      • Type: REG_DWORD
      • Value: 1
    3. Reload the agent for settings to take effect.
  4. If the agent runs on a Windows Server 2003 endpoint without any Microsoft service pack, the OfficeScan firewall may block connection to the integrated Smart Protection Server. Apply the latest service pack to avoid encountering this issue.
  5. The OfficeScan firewall service and driver cannot be installed if a previous version of the firewall driver exists and is running but there is no Trend Micro Common Firewall in the network protocol.
  6. OfficeScan does not support specific application exceptions on Windows 8 and Windows Server 2012 platforms. OfficeScan allows or denies all application traffic on endpoints with these platforms.
  7. The OfficeScan Firewall driver version appears as 1050 on the web console dashboard. This is due to Windows XP platforms being unable to update their Microsoft signatures and not being able to report the correct driver version to the server. To verify the actual Firewall driver version, check the agent console directly.

Smart Scan

  1. Only Internet Explorer is supported for configuring proxy settings used by agents to connect to the Global Smart Protection Server. If proxy settings are configured in other browsers, agents will not be able to connect to the Global Smart Protection Server.

Web Reputation

  1. If the OfficeScan server is installed on a dual-stack (IPv4/IPv6) endpoint and is using an Apache web server, pure IPv6 agents cannot send Web Reputation queries to the integrated Smart Protection Server.
  2. If you enable the option Check HTTPS URLs in a Web Reputation policy:

    1. Select the option Enable third-party browser extensions in Internet Explorer. If this option is disabled, agents will not be able to check the reputation of HTTPS websites.
    2. For agents running Windows Server 2008 (32-bit), disable Internet Explorer Enhanced Security Configuration (IE ESC) from Windows Server Manager. If IE ESC is enabled, the Web Reputation blocking page displays in source code mode.
  3. The OfficeScan agent is unable to get the Web Reputation rating. This occurs if the agent is installed on an endpoint running Windows Server 2008 (32-bit or 64-bit) or Windows Server 2008 R2 (64-bit) with Apache that supports IPv6. As a workaround, turn off IPv6 on the endpoint.
  4. Agents can browse blocked sites if using Juniper Networks VPN and proxy servers to connect to the Internet. To resolve this issue:

    1. Connect to the network using Juniper Networks VPN.
    2. Open Internet Option > Connection > LAN Settings.
    3. Disable Automatic configuration settings.
    4. Enable Proxy server and specify the IP address and port of your proxy server.
    5. Click Ok.
  5. If users access the Internet using Firefox and a proxy server, be sure that proxy settings in Internet Explorer have been configured. If proxy settings have not been configured in Internet Explorer, Web Reputation will not work, even if proxy settings have been configured in Firefox.
  6. On the OfficeScan agent endpoint, Web Reputation automatic proxy detection in Internet Explorer does not work if the administrator enables the OfficeScan Agent Access Restriction option on the OfficeScan server web console's Privileges and Other Settings screen.
  7. After upgrading, the Web Reputation Services is unavailable until the Web Blocking List is fully updated. To resolve this issue, go to Smart Protection > Smart Protection Sources and select a secondary Smart Protection Server for agents to use until the Web Blocking List has completed the update.

    Note: OfficeScan begins updating the Web Blocking List immediately after the server upgrades.

  8. After upgrading to 11.0 SP1, customers who previously installed Hot Fix 5727 must reapply the EnableWrsStatusRealtimeUpdate setting to the Ofcscan.ini file. Hot Fix 5272 solved an issue where the OfficeScan agent's Web Reputation Services status did not immediately report an "Unavailable" status to the Agent Management screen when the service became offline.

    To enable OfficeScan agents to send the Web Reputation Services status of an OfficeScan agent to the OfficeScan server immediately after the Web Reputation Services server status on the agent becomes "offline":

    1. Open the "Ofcscan.ini" file in the "\PCCSRV\" folder on the OfficeScan server installation directory.

    2. Add the following key under the "Global Setting" section and set its value to "1".

      [Global Setting]


      Note: To disable the solution, set "EnableWrsStatusRealtimeUpdate=0", which is the default configuration.

    3. Open the OfficeScan server web console and go to the Agents > Global Agent Settings page.

    4. Click Save to deploy the setting to agents.

      The OfficeScan client program automatically installs the following registry key:

      Path: HKLM\SOFTWARE\TrendMicro\PC-cillinNTCorp\CurrentVersion\Misc.\

      Key: EnableWrsStatusRealtimeUpdate

      Value: 1

Control Manager Integration

  1. The Integrated Windows Authentication protocol is not supported when registering OfficeScan to Control Manager and specifying web server authentication credentials for the IIS server. Only basic access authentication is supported.
  2. When accessing the OfficeScan server using the single-sign on function in Control Manager:

    Refresh the page if any of these conditions occur.

  3. The Control Manager server must use port 80 or 443 to allow migration from the Trend Micro Management Infrastructure(TMI) protocol to the Trend Micro Control Manager Management Communication Protocol (MCP) agent.
  4. OfficeScan agent registers and unregisters to Control Manager if the mobile agent frequently changes IP address. This can cause network bandwidth issues for Control Manager 5.0.
  5. Outside Server Management reports cannot be queried if the OfficeScan web console is accessed through Control Manager single sign-on. Use the OfficeScan web console to query Outside Server Management reports.
  6. When obtaining the Suspicious Objects lists from Control Manager, OfficeScan does not subscribe to or synchronize the User-Defined Suspicious File List.

Online Help

  1. The Online Help system experiences scripting errors when viewed using Internet Explorer 8.0 and earlier. Apply the following Windows fix to solve the problem:

Virtual Desktop Infrastructure

  1. Windows 2003 virtual platforms cannot connect to vCenter 5.x or later using SSL connections (port 443 with HTTPS).
  2. Windows 2012 virtual platforms cannot connect to XenServer 5.x using SSL connections (port 443 with HTTPS).
