Hi all,
For a few years we've had a small Windows application created with PyInstaller. It connects the PhotoFinish in a Track & Field stadium with a cloud service. It's very simple, with Tkinter, requests to talk to the web, and reads and writes local test files; nothing else. It gets downloaded by quite tech-unsophisticated users (typically above retirement age) on the morning of a race; they just drop it on the desktop and run it, no installation program.
Last month Windows 10 started to tell people this was a virus. Unfortunately our users are very often first-time users, and the steps to make Windows shut up and install it are quite complex and scary. VirusTotal.com reports that it's 100% clean.
The app is here (feel free to try it, just drop on the desktop, run and you will see a window):
I reported a possible false positive to Microsoft and they said this: "Analyst comments: The submitted files do not meet our criteria for detection. No detection will be added for these files." I think that means "we don't care enough about you" :-(
This is about the third time I have had a false positive from a single EXE made with PyInstaller in the last decade. Can anyone suggest ways to mitigate this? Does anyone know of settings or things-included which are likely to cause this, or to mitigate against it?
Any ideas if it's the EXE itself, or the fact that it does not come "wrapped" in an MSI or InnoSetup-type installer?
Many thanks for all help
