We don't know how Google's grading works, but you may be on to something. I publish several free tools and games for Windows, and they're all raw executables without any kind of code signing. Internet Explorer continuously blocks them and scares the users away from them. Neither Firefox nor Chrome trigger a warning on them and seem to recognize them as harmless.
