I think you’re getting paranoid. All douse keys are just registry legtovers. AdwCleaner is a tool with high detection rate and it does check registry using his own database very thorough.

Your system is malware free. And when it comes to the PUP software, you just need to learn how to install a program ( isn’t all in “next> next> finish” you need to be carfull and to read what exactly you install ).

You may read this article. We (AMF Tim) where write in my home forum on my native language so you’ll need to use google translate (serbian > english).
