Heur.ExeHeaderH on virus total says Ad-Aware on my download also, i check both the art book and the game. I did not open any of the files!!! Just dragged them to virus total and did a microsoft defender scan.
Only the game seems infected, the art book is clean, but only virus total found the @virus. Its strange how the other comments dont mention this.
Sucks since the game seemed to have a nice art style, i deleted my files instead. Not worth the risk.
