Level 1
As for the behaviour blocker in Avira - does it even exist, or it's just of such poor quality and performance? I've seen them develop a ProActiv guard, but i don't know if it's not finished, or only unavailable for 64bit systems (how can that happen in 2016 is not known to me).
As from what I gather, Avira's signatures are very good, but people complain over its behaviour blocking.



Level 5
Seems that they have some kind of a behavior technology, but not like AVG Identity Protection or Panda's TruPrevent or Bitdefender's Active Threat Control or even Comodo's Viruscope. Avast have HIPS but haven't heard of behavior analysis protection. They have Evo-gen which is a way to automatically classify new files when comparing them to other files but not a behavior blocker.
