I'm aware of the situation and made some quick code clean up after seeing that the anti-virus companies won't react and even copy their false results from each other.
I deleted some unused functions for example and the false alarms got better with the latest version (0.3.9.7)

All changes are documented and transparent.
But: "Burst finally goes viral"
