Any idea for Palo Alto Sample Malware File not deteceted on threat emulation

[GabsOliv]

Hi all

Was testing threat emulation on SMB appliance,  using competition files.

"No threats found in file downloaded by 10.10.6.100 from http://wildfire.paloaltonetworks.com/publicapi/test/pe"

 Any idea How can we explain to the client that a file is malware on the blue vendor, and here is considered benign.

Have a nice day
