Why do Chrome and SmartScreen swear at the program?

Question

Python

Wrote a program using Python+PyQt4. After compiling with cx_freez and packaging using Inno Setup, SmartScreen on Windows swears. And when downloading a file from the site, Chrome writes that the file is dangerous.
Why is that and how to fix it?

Answer 1

also try wrapping it in UPX
SmartScreen sees the installer of some little-known tool and swears just in case.

Answer 2

there is no way to fix it, packing with standard packers is always crap about a virus, samrtscreen swears at all exe files, except for those signed with a key (you can’t look for a free file signature on the net, then everything they write is crap), at the expense of chrome, chrome can be bypassed, send for example through mail.ru a letter to yourself and when you open the exe everything will be good
