Like Bob, my free version is the same as yours. I also have a “paid” AIS license.
Many “avast evangelists” have both the free and a paid version.
In fact some evangelists use only a paid product.
To condemn someone for using the free version is rather closed minded.
Many users who purchase a paid product usually start out using the free version.

Your statement about avast has every right to “nag” is correct. However too much “nag” chases potential paying customers away.
Therefore those who use the free version have every right to complain.

I do fail to see why a separate childboard for paid versions should be created.
Especially when “paid” users get the same assistance here. Not once has anyone
using the free version ever told a user with a paid product “to chill”. Most evangelists
have at least some knowledge of the workings of the paid products.
