I have just noticed that Spybot S&D is not listed in CCleaner 2.08. It's installed in the default location and shows up fine in CCleaner 2.05.555
You are right.
The key to detect Spybot S&D is no longer:
HKCU\Software\PepiMK Software\SpybotSnD
It's changed as follow:
HKCU\Software\Safer Networking Limited\SpybotSnD
