This is a false positive that sometimes appears as we pack our executables for Mapillary tools with Pyinstaller and some antivirus software can sometimes flag them. The bundled executable is from [Release v0.13.3 · mapillary/mapillary\_tools · GitHub](https://github.com/mapillary/mapillary_tools/releases/tag/v0.13.3) Check your anti virus software for options to remove a file from quarantine or specify an exemption. ---

> [@nikola](#): > > Check your anti virus software for options to remove a file from quarantine or specify an exemption. No, and I really hate to disagree with you @nikola but the solution is to add an [Authenticode](https://learn.microsoft.com/en-us/windows/win32/seccrypto/cryptography-tools) signature to Mapillary’s Windows executable. If you need or want to build the Windows executable on a POSIX system then you can use Mono’s `signcode` in place of [`SignTool.exe`](https://learn.microsoft.com/en-us/windows/win32/seccrypto/signtool). ---

Just FYI @nikola: Alternatively, you could provide a free of charge MSIX package on the Microsoft Store. It is really easy to build and even easier to manage because the store provides automatic updates. [The Microsoft Store signs MSIX packages automatically by design with its store certificate](https://learn.microsoft.com/en-us/windows/apps/distribute-through-store/how-to-distribute-your-win32-app-through-microsoft-store#distribution-options--select-the-one-that-works-best-for-you "see the table"), so that you would be relieved of managing your private key and code signing certificate. MSIX and APPX apps are installed into a _special_ Windows managed location which is usually automatically exempt from anti-virus scanning because all files there come from a trusted source. I do not know whether the Microsoft Store also signs any signable package artifacts, like `exe`, `dll`, `cab`, `msi`, `ocx`, `sys`, etc. files (would be nice and smart if they did). ---

That’s a good idea, we’ll look into that as an option!
