As far as I can figure, the Dr Watson Postmortem Debugger is a Microsoft program installed on Windows XP units.
The program is basically designed to crash when it detects that another program crashes and creates a log of it.
This program was replaced by the modern crash reporting system built into all modern Windows operating systems.
This program can remain on your computer if you have it, however, if it causes your system to perform slowly, or you wish to remove it, there are several ways to do so.
I unfortunately have not yet successfully disabled it, however, there are numerous methods and websites accessible from Google to help you remove it.
