Thanks for bringing this up! We're investigating it right now. Most likely, it's a incorrect detection, but we're double checking on this.
We've checked this and it turns out that one anti virus program out of 69 flags the game as a trojan (https://www.virustotal.com/gui/file/97dbab2a33db5dba27133236cccd1781c3baae6ed168dbf5f980c6c2dabd6dce/detection). Apparently this happens to unity games from time to time (https://forum.unity.com/threads/anti-virus-problems.78979/page-3).
What this means, is that it's a false positive.
I can assure you that we have not put any malicious code into the game.
Most likely the next version will not have this issue anymore.
