OK, I agreed you guys are right. Here's how I got the update to work:
1) Go to Tools > Advanced Settings
2) Highlight PUP (Potentially Unwanted Programs) Exceptions
3) Add the following exceptions:
C:\Program Files\Stardock\Impulse\Impulse.exe (check the Any Location box)
C:\Program Files\Stardock\Impulse\ImpulseSelfRefresh.exe (check the Any Location box)
C:\Program Files\Stardock\Impulse\CleanImpulse.exe (check the Any Location box)
C:\Program Files\Stardock\Impulse\7z.dll
C:\Program Files\Stardock\Impulse\ImpulseMini.exe (check the Any Location box)
Thanks for the help guys, both you and those who posted in the other suggested thread.
