Likely everything you're doing have been done in various Trojans, viruses, etc. You'll need to hack the noosphere at this point
Of course if you get these vendors to fix their detections for your program and get google "safe" browsing and virus total (aka google again) to stop slandering your it will only take time before the whole thing starts again - even without any changes to your executables.
And beacuse these are respected™ software companies making the virus allegations your users will of course more often than not tell you to fix your executables when the bug is in their third party anti-virus software.
I'm getting more and more tempted to just not provide any Windows executables for my open source projects :/
