Trojan with Windows Lagrange? about lagrange HOT 10 OPEN

This is a false positive as far as I can tell. I'll see if I can do something to clear this up.

Can you remember what version you were upgrading from (to 1.17.5, I assume)?

One thing to try is uninstalling the app and reinstalling it, or seeing if Windows is happier with the "portable" ZIP version of Lagrange.

I think it was 1.17.3. I definitely remember that I wasn't upgrading from the obvious immediate predecessor (1.17.4).

Around that time (1.17.3) I switched the code signing certificate that I sign the app with on Windows. Perhaps that contributed to this?

You should be able to verify in the file properties that both the lagrange.exe and the uninstaller exe have a valid signature by "Open Source Developer, Jaakko Keränen".

The code-signing certificates seem as you describe them, although I haven't looked at all the fine print:

Is there anything else I can peek at on my end to help figure out if this is a real or false positive? My Windows machine is usually off, and I don't do general web browsing on it. Mostly I just turn it on to let it update itself, its Steam games, and bask in the calmness of a computer that isn't set up to do much.
