Hi Aurel,
On VirusTotal, we usually get false positives from Antivir. I tested the 32 and 64 bit binaries of one of my Apps: projectsA/OpenglGui/Viewer. The 32 bit binary was flagged by Antivir but none of the other 48.
One possible solution is to release 64 bit binaries, but you would also need to have a 64bit Windows Scintilla.
However, the virus checker on my PC (Avast) is so aggressive, I often have to turn off the shields to download binaries. I presume it uses high-speed but rather paranoid algorithms to block anything that looks unusual.
