I'm trying to run some simple npm run scripts  (https://www.npmjs.com/).  How do I exclude such events?

Here's the output

After "Exclude a previously detected Exploit", I am presented wth a menu which asks me to select and identified exploit with two fields in which I cannot enter anything (one for an exploit hash and the other for an application). However, there is a "Select" button.  If I click on it, there are exploit shown that I can select.

 

I did try to add an exclusion for cmd.exe (which seems rather broad ... but just to see what would happen) and nothing change.

 

Note that I can run the exact same script  many times in a row and that sometiems it runs correctly, and sometimes it is prevented to run by Malwarebytes.

Hey Aroberge,

 

It should only exclude the script that CMD was calling at that time. However, if it still gets prevented, I want to see the logs for that. Can you reproduce the issue again and when you do, collect these logs for me:

 

C:\ProgramData\Malwarebytes\MBAMService\mbae-default.log

C:\ProgramData\Malwarebytes\MBAMService\logs\MBAMSERVICE.log

The directory is hidden by default so you might have to click on "View -> Hidden items" in Explorer to see it.   There is also a post here from Microsoft on how to do this for the more recent OS: https://support.microsoft.com/en-us/help/14201/windows-show-hidden-files
