Hi,
Regarding the following article from technet we setup a TMG 2010 a couple of years ago for the purpose of malware inspection.
Last week we had some pentesters to run some test on our network and to our surprise a Zeus virus could be downloaded en upload to a random selfmade server via HTTP and TMG allowed the connection.
My settings are the following:
Malware inspection is enabled
No source and destination exceptions are defined
Image may be NSFW.
Clik here to view.
NIS and Malware inspections are up to date.
The link to the technet article is:

Could you please help me find out why TMG 2010 is not scanning for the any malware? We tried with Cryptolocker and Zeus. Virustotal ratio is min. 52/57.
