Questions about HIPS

1.) Is it working now if you only have “Monitor malware like behavior” enabled?
2.) Does sensitivity setting affect both settings or just suspicious activities and not malware like behavior?
3.) Is HIPS working on top of rules learned from DeepScreen/Dyna (this has been operational for a while so it would make sense) or is it just a direct port from old avast! versions?
4.) Any preliminary internal test results? Does it actually detect and block malware or is it just as passive and useless as it used to be in older avast! versions?
5. Are there again any limitations on 64bit OS (it used to be a limitation in the past)?
