Norton NIS / NAV / N360 detect keyloggers as "Spyware"  so that the detections will have "Spyware.xxxxxxxx"  say for instance "Spyware.KGBspy"

For a bit of information.

As for the Norton Power Eraser, I agree it should be as a last resort due to the Files that can show as False Positives etc. Other programs should be tried first.
