Malwarebytes Beta is being flagged as malicious

Hello, I have been trying to download some of Malwarebytes beta software from there forum, from malwarebytes.com the real site, and Norton keeps flagging it as dangerous.  I have tried everything I know.  Is there a way to fix this.  I tried to put it in the excluded folder but no success, now it just gave me a pop up that it needs to restart to clean the security risk, that I have only been working on for the last half hour or so.

It won't let me recommend an action it just deletes it.

 

Help,
