Internet Explorer zero-day and 'mht' file type

[Dan_Roddy]

A zero day exploit of the mht file type has been disclosed.  I checked the file types sandblast is designed to emulate and 'mht' is not in the list.  

How do new file types get included?  Can I add new file types through the Endpoint client?

We would have to add explicit support to emulate new files.
However, they can be blocked in the Threat Prevention profile using the AntiVirus blade.
