The online description at Pest Patrol states:
* Captured data is stored encrypted, in dated files (ex. '01.20.99.DAT') and can be deleted through System Spy interface.

This is probably what is causing the false positive. I have performed a scan on a system that has been freshly imaged. You will have a fair number of .DAT files on every standard Windows system. Pretty ineffective scan if it relies on file names only and doesn't try to validate content. Pretty effective marketing tool if your target audience is the average home user...

Your post piqued my interest, so I ran PestScan myself. I got quite a few
false positives.

I combed through the results and it seems to me that PestScan will give a
positive when it finds
a file of the same name as a file used by a piece of spyware.

For example, I got a positive for System Spy, too. The only thing I could
find on my system that matched with Pest Patrol's descriptive data for
this spyware was under "File Analyses". The file name was setup.inf.
It's not surprising that I
had a file of this name on my system. And it wasn't the System Spy file.

Can anyone help to confirm this "false positive by file name only"
scenario?

Thanks!
