Appears t o be related to pivot monitors and may come either with ATI software, or Pilotware as supplied by Viewsonic for their pivoting monitors.

I would like to think that TVICHW32.SYS is not a threat as I have a ViewSonic PivotPro Monitor on my desktop, but I found the identical file on my laptop. The 2 files said they were created within 10 days of each other and both many months after the last time I updated my drivers. Therefore I conside it suspicious enough to remove.
SpyBot marked it as a threat during routine scan.

Non virus. Its a harware driver, for me used as a secondary custom keyboard
Annoying. Something keeps pointing to this at boot up. Driver Agent does not want to go away(many un installs).
TVicHW32 is a general purpose device driver that can be used by practically any programming language. It lets you access and control hardware directly from any Win32 application under Windows 95/98/Me/NT/2000/2003/XP/XP 64-bit without having to use the Windows DDK.

This driver is the remnant of a driver update check, so it is a driver which apparently scans for other drivers. It should properly have been uninstalled after the scan but wasn't. I am 99.9% sure of this; the time installed on my system tallies and examination of the url in my link below reveals heaps more evidence. Of course it might also be used by other driver scanning companies or programs. Try deleting it (I did), but set a System restore Point first just in case!

Best practices for resolving tvichw32 issues

A clean and tidy computer is the key requirement for avoiding problems with tvichw32. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic 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 resmon 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 DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
