What do you mean by "Seem to do nothing"?
Exactly what i said. I haven't seen a SINGLE alert from behavior shield. Not one. And i was throwing everything at it.
ThreatFire? No problem, throw at it and it will jump on it sooner or later. Kaspersky Antivirus 7 (yes, the very older version), same. It actually cought very new samples with very outdated behavior module because they aren't updating it anymore for a long time.
But avast!. Ok, it has the shield, but for me it doesn't do anyting. Same goes for AVIRA ProActiv that basically works the same as the one in avast!. Nothing from it at all. Like it's not even there. Now if you add something like that to the program i'd expect to see at least 1 detection. Just one would be enough. But nothing, makes me question it's effectiveness.
