If a new virus has been detected on a PC that is not yet in Virustotal, how can it be isolated, blocked until the problem is solved?
Thank you for reporting.
CAV has Auto-containment setting which is supposed to block/isolate if the new virus is detected.
Refer the below link for better understanding.
