Thanks for the response, I can say for certain I have never clicked accept on a page like that or even a blank page that would have only an accept button.
I just noticed at 7AM after an auto update of CCleaner that I had an avast icon on my desktop.
I am running ESET Antivirus, I have never intentionally blocked any connections manually or seen any issues in all the years of having CCleaner installed up until this most recent update.
