NPE-Beta finding no problems except itself

I ran a NPE-Beta scan and it found no problems but itself.  I'm suspicious of a problem because I clicked on a google image that redirected me to something that used 99% of one of my CPUs.  Norton IS 11 gave a pop-up at the time that Firefox was using 99% of my CPU but did not find the virus/trojan or whatever it was that was doing it.  So I downloaded NPE-Beta and ran a scan and found it strange that it found itself.  NPE-Beta.exe (bad) was the find.  I didn't use it to delete it as I figured that was impossible.  I re ran the scan and it didn't show up the second time.  Is this wierd or what?

 

I ran all the free spyware programs I could find and nothing found anything.  I keep getting medium alerts in Norton that my conhost or system32\mrt is trying to target various Norton Internet Security Engine\18.1.0.37 etc. 

 

I restored to a point before I clicked the google image virus... then I did a full factory restore then I did a restore to disk image after that using DVD's I made when I first got the computer.  After all these restores/factory resets.. I ran the Norton Power Eraser Beta and it found itself.  I'm still getting the medium alerts that various windows processes are trying to access Norton IS Engine.  Pretty sure I haven't solved the problem yet - either that or there was no problem.  However after clicking on that google image I got a huge influx of medium alerts from Norton about processes trying to access various places.  Also I would notice strange flashes on my screen when I went to save things.  The save window would appear for a split second in the upper left corner of the screen and then move down to where it usually is.  Not a big deal but this didn't happen before the google image virus.  Then after all the restore I found it odd that Norton Power Eraser beta would find itself as the only problem on my computer and recommend deleting itself... Wierd right?
