To make sure that our releases are clean we apply best practices like generating the Windows binaries on Linux servers running Wine. We test the binaries to the last detail with various AV packages. Malware analysis is also incorporated to get to the ground why some AV packages report the binaries as infected but to no avail. The heuristic engines of major AV vendors are tuned very severely, and there is no way of getting around it for us developers.

Yes, we are using this reporting tool frequently. Every single file we ever submitted to Microsoft was confirmed by them as a false positive. The definitions were updated, and it was fine. The AV behavior changed again, once they "tuned" their heuristics and the game repeated itself. The only difference was the type/name of the infection, which was still a confirmed false positive.
