Anyone who knows how to properly clean and maintain their system will tell you there is no need for these types of software, the vast majority , if not all of them cause more harm than good, ASC being more towards the top of that list.
I used to be a firm believer in these types of software, including CCleaner and was finding I was doing system refreshes or OS re-installs sometimes twice a year, since I learned how to clean and maintain my system without the use of them I have not had to do a refresh or reinstall in over 5+ years now , my system runs like it did the first day it was installed........ if that isn't a hint and a half for you I don't know what is.
