Fair enough answer for now.
You might also take a more proactive approach and included test-runs with various tools like the one from Secunia to iron out “falls-positives” before it gets released to the public. Just saying these tools a free.
Frankly I would expect Avast! to fix this detection error from their end and not Secunia. This would to me be a sign you are dedicated to show the community you take issue’s like this seriously as you make the software available.
(Like adding this to release notes if no workaround is yet known.)
