NPE finds Firefox problem on multiple PC's

Hello,

 

I ran NPE & it found the following problem with FF:

 

HKEY_LOCAL_MACHINE\SOFTWARE\Clients\StartMenuInternet\FIREFOX.EXE\shell\open\command\""

 

File Thumbprint - SHA:

 

It was listed as - Risk: Registry, Type: System Settings, Status: Bad. I took the recommended action & repaired it which included a reboot.

 

I had run NPE a couple days before the recent FF upgrade & it had not found any problems ( My system: Win 7, x86). I had also run it on my wife's laptop at the same time, which showed nothing. Her laptop did not have access to the net after the scan.

 

Curious, I updated FF on her system (Win 7, x64) & ran NPE & it found the same problem. False positive or something that shouldn't be in the FF code? Your thoughts please....

 

Thank You
