I also am encountering false positives with TechTracker which seems incapable of recognising that I have updated the following:
FTP Voyager
Snagit
CDBurnerXP
I have wasted time uninstalling, downloading, reinstalling and generally chasing my tail.
This all started about two months ago - till then TechTracker was a delight.
My two reports on this have been ignored.

Your TechTracker says that my Ad-Aware is out of date becuase the installed version is 8.0.0. and the current version is 8.1.0. Actually the installed version is 8.1.0. It also says that my Western Digital Dara Lifeguard Diagnostics for Windows is out of date becuase the installed version is 1.9 and the current version is 1.13. This does not even make sense. Unfortunately, TechTracker seems no better than VersionTracker, which found numerous false positives.
