I assume you mean the Android version. A few anti-virus believe it has a trojan. I cannot explain why it thinks that, but Avast is wrong. It's a false positive, and it's virus free. The game doesn't even connect to the internet like that, it's totally user-side. But if you are not sure, or you want to hold someone accountable, you can find the person who makes the Android Port here https://discord.gg/n3q28qDUa6
