False Positive Virus Detection for app2exe-Generated Executables

[shiromofufactory]

There have been cases where files converted to executables using the app2exe command are detected as viruses by security software such as Windows Defender and Norton.

This issue seems inconsistent, as even minor modifications to the same program can cause files that were previously undetected to suddenly be flagged. Reproducibility remains unclear. However, after some investigation, it appears this phenomenon is a commonly discussed topic related to PyInstaller.

Example:

I also found information suggesting that rebuilding the bootloader could resolve the issue. However, in my experience, there seem to be scenarios where this method successfully avoids detection and others where it does not.

Has this topic ever come up during Pyxel development?
