I just installed AVG Anti-Spyware trial. Ran a Fast System Scan with nothing detected. Ran a Complete System Scan and found Trojan.Inject.av with 8 infected objects. The 8 infected .exe files are located in a seldom used program which is "IMSI Floor Plan". This program is part of the original software package supplied from Gateway with this XP computer. I strongly suspect that this is a false positive detection. I attempted to find a way to submit a bug report to Grisoft. This appears impossible to do without paying for a registration code for their prog. It is quite a surprise to discover that Grisoft is not interested in receiving info of this nature. This is not a request for support from this board or Grisoft, Just a heads up for other users. Thanks.

You didn't try their technical support pages? As far as I can see, all they ask there is a email address.

Thank you for the Ewido link. My mistake was the false expectation that Grisoft technical support would be dealing with the technicals for the program that they now distribute, sell, and label as theirs.
