Now it is called Active Threat Control
Bitdefender Antivirus Free uses an innovative technique called behavioral detection to closely monitor your active apps. When it detects anything suspicious, it takes instant action.
I tried a few weeks ago to use Bitdefender Free, and I tried to do a full system scan with it. About half way through the scan it quit and poof it was gone from my system tray. Anyone else experience this from Bitdefender Free?
It's getting better and better than the first released version (for windows 10). Delay issues has been fixed and self-learning works great as well. The only thing I found uncomfortable is the scanning speed expecially the demand scan. When I'd like to scan a folder, BD did it way too slower than other AVs but resource usage when scanning is pretty the same.
