Maybe I shouldn't have used the words False Positive to describe this.
The Avast engine does not detect this file as malicious. There is nothing in the chest to send. Sending in the file to virustotal does not show a detection by any antivirus.
When I scan the file with Avast, it doesn't detect anything. This was a behavioral false positive.
It was not the normal notification that shows up when avast has a detection. Instead, it was an alert in the center of the screen that said rootkit detected. I should have taken a screen shot.
