I bought Avast because I was happy with the free version and thought I’d pay for it… at the time I thought Cleanup was included since it was displayed on the report screen. Not real happy that when I clicked on Cleanup I was notified that it cost an additional $19.99/month! Happy with virus/malware protection & unhappy with what bordered on false advertising.
There is no false advertising, just you who didn’t read properly and/or don’t understand things.
It is very clear that CleanUp is a separate product.
