I have been using ccleaner BEFORE piriform started it. It was created by the Brown Bag company. Piriform agreed the amount to be paid by Piriform, the “condition” was piriform was NOT allowed to change the name, then it was called “ crap cleaner “, thus piriform keep the name as ccleaner and called it Computer Cleaner. same ccleaner. 
RE Version 7.0…. This version creates “BLOATWARE”. Will piriform ever FIX version 7 ?
