Go Up one level from Avast Premium to Avast Ultimate ?

I have just up-grated from “Avast Free” to “Avast Premium Security”.

I like it !
*
Now I wonder if I could go feather ?
*
Up one level more - To “Avast Ultimate” …
*
Is this the best ? (Yes, I guess so). - But what can it do more ?
*
It here ALL extra included ?
*
It it so good ?

If I dacite. Can I get it with extra money. - Not a whole new buy. - I have just bought “Premium”. 3 days ago.
