wtf?
But these are not data from the original game or the HongFire patch...
I see you downloaded the game from the first post...
If you go a few posts above you will find clean packages with nothing abnormal, I found the clean installable version and the two extras, even further above a pre-installed package was made more convenient if you don't want to commit too much to play it.
However, the antivirus is reacting to a modding tool or similar.
You are only interested in;
- The ISO (Образ игры [Main Game]), from what I see it has not been modified to work on non-Japanese systems.
- The patch (Вспомогательные/School Mate 2 HF Patch.exe), It has everything you need to have the game updated
- The Registry Fixer (Вспомогательные/Утилиты [Utils]/RegistryFixer), if necessary
Everything else is useless.
