I have been using Ccleaner Pro for years, starting back to when it was owned by Piriform, before being purchased by Avast and before the breach. Every update has been slower in terms of performance (and yes my laptop can more than handle it), even on brand new installs as well as the forced upgrade to v7. Version 7 is pure crap. It is the slowest version ever and the lack of being able to clean everything due to some technicality etc. using the custom cleaner is just ridiculous. Every update this program has received has been worse and worse. The driver and software updaters have become so slow that even updating one program takes 10 mins at times. Good bye Ccleaner.
