I am want to know, when Avast 2017 products will be out from the beta testing and will be able the stable release versions of Avast! 2017? At February or March 2017, I guess?
Check back at the forum now and then. 
The exact date cannot be released yet, but like all avast! releases from the past, it’ll happen before March. There will most likely be another beta first and probably a short RC release and then a final version. Keep checking back here to stay up to date.
