I understand your feelings and it's a catch 22. avast! ver. 7 is the product that is rated #2 now, and NOT version 6. So I understand the concept of the push to version 7 by Avast Software, as they are trying to give us the best protection they can.
And yes, it scares me when the push occurs. However, all of this WAS in your control, as the reseller, to configure the program updates to manual (especially on servers)
The default of auto updates is a necessity for most users, because they will NEVER do any update. I discuss this issue with my clients. I tell them the truth.
There is no useful software that is bug free. By the time it is bug free, it is obsolete! J.R. Guthrie
