bug finder is here XD
This is truly normal. It is not a recognizable file as most of the other games, and also it has such a low number of downloads, that it probably has not been added to the anti-virus database as a game.
You can disable your anti-virus and trust my word, or you can run the game in the safety mode (which your anti-virus should include).
If you have any additional trouble running the game, please, inform me ;)
