Idk. When I tested the beta version of Avira almost one year ago, I already noticed that the context scan function was missing. The developers promised that this function was on the roadmap, which is not true. 
I think Norton will use Avira detection technology sooner or later. But it does not appear to have allocated enough money or technical staff to Avira.
I am using ESET + Kaspersky Anti-ransomware tool now.
