Despite the problems Avast has (as any other Security Suite product) it is for sure more reliable than “free cleaners claiming $$ for something”! It seems your PC has either some kind of virus or just some program stuffed with ADs and similar stuff that is annoying… I would recommend you to uninstall these “cleaners” (maybe with Revo Uninstaller or other program that better clean registers and leftovers than the standard uninstallers of these apps!) and reboot. Clean the registry once more (with something non stuffed with Ads like CCleaner) then perform a Boot Scan with Avast to see if any “real threat” is on your PC!
