Cylance seems to hide+lock threats until full qualification is made. Once it's determined (fully) to be malicious, then it's purged. If it is determined safe, or you allow it, then the flags are removed and Cylance unlocks the file right back where it was. This is also why testing must be carefully conducted as many on-demand scanners will detect those benign hidden+locked files as being actual malware sitting there. You can demonstrate this for yourself, download malware, wait for Cylance to lock it for qualification, then scan the folder with HMP or Zemana, the malware will show up as being there. Don't trust secondary scans without manually inspecting the folder each time (AND the temp folders, etc) to make sure the file is actually there, in many cases, it won't be but those scans make make you think the machine isn't clean. I've noticed on 'tests' that secondary scans showing an unclean machine are actually files that are contained but have flags, and still show up on secondary scans. A hit and quarantine, reported as a miss.
