What are PtSessionAgent.exe Error Messages?

PtSessionAgent.exe Runtime Errors

Runtime errors are Trend Micro Antivirus Plus Security errors that occur during "runtime". Runtime is pretty self-explanatory; it means that these EXE errors are triggered when PtSessionAgent.exe is attempted to be loaded either when Trend Micro Antivirus Plus Security is starting up, or in some cases already running. Runtime errors are the most common form of EXE error you will encounter using Trend Micro Antivirus Plus Security.

In most cases, PtSessionAgent.exe runtime errors occurring while the program is running will result in the program terminating abnormally. Most of these PtSessionAgent.exe error messages mean that Trend Micro Antivirus Plus Security was either unable to locate this file on startup, or the file is corrupt, resulting in a prematurely-aborted startup process. Generally, Trend Micro Antivirus Plus Security will be unable to start without resolving these errors.

Some of the most common PtSessionAgent.exe errors include:

PtSessionAgent.exe - Bad Image.
PtSessionAgent.exe Application Error.
PtSessionAgent.exe could not be found.

System Error

The program can’t start because PtSessionAgent.exe is missing from your computer. Try reinstalling the program to fix this problem.

Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.

Finding the source of the PtSessionAgent.exe error is key to properly resolving these errors. Although most of these EXE errors affecting PtSessionAgent.exe will happen during startup, occasionally you will encounter a runtime error while using Platinum. This can occur due to poor programming on behalf of Trend Micro Inc., conflicts with other software or 3rd-party plug-ins, or caused by damaged and outdated hardware. Also, these types of PtSessionAgent.exe errors can occur if it has been accidentally moved, deleted, or corrupted by a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.

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

Restore your computer to that backup image.
