What are tmusa.sys Error Messages?

tmusa.sys Blue Screen of Death (BSOD) Errors

There are a number of reasons why you could be encountering issues with tmusa.sys. Most of the issues concerning sys files involve Blue Screen of Death (BSOD) errors. These types of tmusa.sys errors can be cause by hardware problems, outdated firmware, corrupt drivers, or other software-related (eg. Trend Micro Antivirus Plus Security update) issues. Some of these errors include:

tmusa.sys could not be found.
tmusa.sys failed to load.
The file tmusa.sys is missing or corrupt.
Windows failed to start - tmusa.sys.

A problem has been detected and Windows has been shut down to prevent damage to your computer. The problem seems to be caused by the following file: tmusa.sys.

:( Your PC ran into a problem that it couldn't handle, and now needs to restart. You can search for the error online: [BSOD] (tmusa.sys).

STOP 0x0000001E: KMODE EXCEPTION NOT HANDLED (tmusa.sys) STOP 0x0000007E: SYSTEM THREAD EXCEPTION NOT HANDLED (tmusa.sys) STOP 0x0000000A: IRQL NOT LESS EQUAL (tmusa.sys) STOP 0×0000007A: KERNEL DATA INPAGE (tmusa.sys) STOP 0x0000003B: SYSTEM SERVICE EXCEPTION (tmusa.sys) STOP 0x00000050: PAGE FAULT IN A NONPAGED AREA (tmusa.sys)

It's Critical to Resolve Blue Screen of Death Errors

In the majority of cases, you will encounter tmusa.sys BSOD errors after you've installed new hardware, software (Trend Micro Antivirus Plus Security), or performed a failed Windows Update. In other cases, software corruption caused by a malware infection can lead to tmusa.sys Blue Screen of Death errors. Therefore, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.

GEEK TIP : As a rule of thumb, it's always a good idea to create a Windows "Snapshot" backup / System Restore Point before making any hardware or software changes to your computer. That way, it's very easy to restore your system in the unfortunate event you encounter a tmusa.sys Blue Screen of Death error after recent changes.

How to Fix tmusa.sys 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 tmusa.sys 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.

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

If the Step 1 fails to resolve the tmusa.sys error, please proceed to the Step 2 below.

Step 2: If recently installed Trend Micro Antivirus Plus Security (or related software), uninstall then try reinstalling Trend Micro Antivirus Plus 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 tmusa.sys error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

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

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

Download tmusa.sys Files (Malware-Tested 100% Clean)

CAUTION : We strongly advise against downloading and copying tmusa.sys to your appropriate Windows system directory. Trend Micro typically does not release Trend Micro Antivirus Plus Security SYS 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 tmusa.sys and all other SYS files for Trend Micro Antivirus Plus Security. An incorrectly installed SYS file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
