is there a subscribe where i don’t have to buy it over and over again is there a subscribe where i can just relax and now its automatically renew the license ?
You mean a lifetime license?
I’m afraid not.
But some time ago I’ve heard about “Online Protection” program that would automatically renew your subscription. Maybe it comes back 
Anyway, there is a 3-year license for avast and it will warn you before it expires (for you to renew).
i am 100% sure there was a post here a week or two ago, with a guy complaing that he did not want the auto renewal as he had not asked for it!
Yes, you’re right.
