But I am expecting less with the recompiled exe to check the safety of the old one.
You know, so many compiling options can vary the bin, unless we get the exact original compiler and options.
After all we can analyze it out, though it will take much time of a newbie of that kind of analyzing
So that is why open source is so important to us, I believe.
And I think the antivirus program should recognize some code pattern in the exe as danger, without calculating the percentage of the use/useless over total. And most part of the exe do use Windows API, I think.
This is a problem with your antivirus software.
You can recompile, relink WinAos and compare with the downloaded.
Also, in this case, you can analyze the map-file.
Do not forget that in fact WinAos - an operating system that runs under Windows. And many things are not needed for use for most Windows-based programs , but uses virus. Therefore, the warning may occur.
