No warning on downloading of file with cmd extension unlike batch file

Reported by cs.anura...@gmail.com, Apr 18 2017

Issue description

UserAgent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/57.0.2987.133 Safari/537.36

Steps to reproduce the problem:
1. Chrome reports harmful file message on downloading of bat file but it misses to show the same message if the malicious file has cmd extension

What is the expected behavior?
On downloading file with cmd extension browser should show a warning to user like it does with bat file

What went wrong?
If user runs the cmd file then an attacker can take over victim system

Did this work before? N/A 

Chrome version: 57.0.2987.133  Channel: stable
OS Version: 10.0
Flash Version:

Thanks for the report.

nparker: Can you please triage?
Please close this. Not sure why my laptop stopped showing warning but on another computer warning are coming for cmd also

".cmd" will show a warning from any new site, but once it shows up in your history before yesterday and you've clicked to download, it won't show a warning. That's probably what you ran into.

Closing at your request.
