Malware is not detected

I have two malware samples that cannot be detected by KSC (Patch F). I already contacted Kaspersky AntiVirus Lab (KL-1151457), they can’t do anything with the issue that I encountered and asked me to get assistance from the support team.

However, the malware samples have been tested 3 different Kaspersky applications on 3 devices with 2 KSC and 1 KIS.

Scan from Context Menu

Both files are already flagged as Untrusted by KSN.
