This package provides accessibility features for TrackPoint.
IBM Thinkpad TrackPoint (cursor pointer area) module
Running from Windows\system32 and I read that non microsoft programs in this registry could be suspect as viruses. Anyone familiar with this program? I am using a Thinkpad T42 and often update with Levono/IBM that supports this hardware.

I had a user that couldn;'t open Micrososoft Project on their T40 laptop. Under msconfig/startup, I found this executable running. I isabl;ed i from startup, rebooted, and then was able to open Project without any issues. I have no clue what this is for, but it seems to have been causing the issues this user was having.
It's true! The tp4ex.exe is for the trackpoint on IBM Nbs!

Best practices for resolving tp4ex issues

A clean and tidy computer is the key requirement for avoiding problems with tp4ex. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command.
