What are TmvExt.dll Error Messages?


Dynamic Link Library TmvExt.dll Errors

TmvExt.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like TmvExt.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like AMSP_LogServer.exe - to follow. These files were created so that multiple programs (eg. Trend Micro Maximum Security) could share the same TmvExt.dll file, saving valuable memory allocation, therefore making your computer run more efficiently.

Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared DLL file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when TmvExt.dll is attempted to be loaded either when Trend Micro Maximum Security is starting up, or in some cases already running. Some of the most common TmvExt.dll errors include:

Your TmvExt.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Trend Micro Maximum Security), or deleted by a malware infection. Furthermore, TmvExt.dll file corruption could be caused from a power outage when loading Trend Micro Maximum Security, system crash while loading TmvExt.dll, bad sectors on your storage media (usually your primary hard drive), or quite commonly, a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.



How to Fix TmvExt.dll Errors in 3 Steps (Time to complete: ~5-15 minutes)

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your TmvExt.dll issue. These troubleshooting steps are listed in the recommended order of execution.


Step 1: Restore your PC back to the latest restore point, "snapshot", or backup image before error occurred.

To begin System Restore (Windows XP, Vista, 7, 8, and 10):

  1. Hit the Windows Start button
  2. When you see the search box, type "System Restore" and press "ENTER".
  3. In the search results, find and click System Restore.
  4. Please enter the administrator password (if applicable / prompted).
  5. Follow the steps in the System Restore Wizard to choose a relevant restore point.
  6. Restore your computer to that backup image.

If the Step 1 fails to resolve the TmvExt.dll error, please proceed to the Step 2 below.

Step 2: If recently installed Trend Micro Maximum Security (or related software), uninstall then try reinstalling Trend Micro Maximum Security software.

Step 3: Perform a Windows Update.

When the first two steps haven't solved your issue, it might be a good idea to run Windows Update. Many TmvExt.dll error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

  1. Hit the Windows Start button
  2. In the search box, type "Update" and press "ENTER".
  3. In the Windows Update dialog box, click "Check for Updates" (or similar button depending on your Windows version)
  4. If updates are available for download, click "Install Updates".
  5. After the update is completed, restart your PC.

If Windows Update failed to resolve the TmvExt.dll error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.



If Those Steps Fail: Download and Replace Your TmvExt.dll File (Caution: Advanced)

If none of the previous three troubleshooting steps have resolved your issue, you can try a more aggressive approach (Note: Not recommended for amateur PC users) by downloading and replacing your appropriate TmvExt.dll file version. We maintain a comprehensive database of 100% malware-free TmvExt.dll files for every applicable version of Trend Micro Maximum Security.

  3. Copy this file to the appropriate Trend Micro Maximum Security folder location:
    Windows 10: C:\Program Files\Trend Micro\Titanium\plugin\
  4. Restart your computer.

If this final step has failed and you're still encountering the error, you're only remaining option is to do a clean installation of Windows 10.


GEEK TIP : We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve TmvExt.dll problems.

Download TmvExt.dll Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying TmvExt.dll to your appropriate Windows system directory. Trend Micro typically does not release Trend Micro Maximum Security DLL files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing TmvExt.dll and all other DLL files for Trend Micro Maximum Security. An incorrectly installed DLL file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
