Its not detected locally here. It should of been within 10 mins of my last post.
Maybe shutdown Malwarebytes and restart it and see if its still detected.
If you do change it it would have to be whitelisted again for now. You can save some time though by uploading it to virustotal.com as our cloud would get a copy and learn whether its malware or not.
I cant get into specifics but basically it looks for file anomalies similiar to what malware does. Files not signed. Weird version info. Empty sections or packed. etc.
If the file was valid digital signed it goes a long way to preventing fps.
