False positives

Repeated False Positives on several programs.

Scan the program(s) with VirusTotal - CLEAN!

Scan the program(s) manually with Norton - CLEAN!

WHY????

I beta test software (I've been coding since the early 1960's) and some of the betas aren't digitally signed. I click "Allow always" - it's IGNORED!

WHY????

If Norton repeatedly gives false positives, how can I trust it to reliably detect a virus - I've disabled Auto-protect because it clearly is not working.
