You need to submit a "false positive" report to Norton.
The problem is that every time I release a new program they're amazing algorithm says "this is a new program no one is using yet, so it can't be trusted". The problem usually resolves itself in a few days once they have several hundred people using it (or they get enough false positive reports submitted by users).
Here's the virustotal scan on the new version of BeerSmith I did just a few days ago (40+ virus scanners):
