Today DuckDuckGo sends searchers to a bogus site for CCleaner. DuckDuck shows this as the first entry for the word piriform:
If you click it you get sent to this link with http at the front of it: (do not try this at home, I am a trained bungler)

This is the first window of the installer. I let the process continue for a bit in a sandbox before stopping it. Not sure what this software is but it isn't CCleaner. Still have some of the files in the sandbox if they would help anything.
Imitation is the sincerest form of flattery, I suppose, but I wonder how many folks have been duped and are now put out with CCleaner? There oughtta be a law.
