It's not a virus, just don't use the main exe for any doubt, use the direct one I leave here.
EroSekaiSchoolLife-0.2a\lib\windows-i686\EroSekaiSchoolLife-0.2a.exe
EroSekaiSchoolLife.app\Contents\MacOS\lib\darwin-x86_64\EroSekaiSchoolLife-0.2a
It seems to be a Renpy problem that I really don't know how to fix, if someone could help me with that I would appreciate it.
