I’ve played this game this morning, but since 17:44 (GMT+1) Avast updated and now is detecting it as Win32 Evo-gen. I’m pretty sure it’s safe, its a game from Steam, and the developer seems legit since i have all of its games and never ever had such a problem. Seems like a false possitive to me.
The archive has been sent to Avast via virus chest. Just reporting.
