The program may have been infected at one time but was cleaned. There's one trace left. It's still placing a registry entry for minigolf_affiliate.exe but it's invalid, points to nothing. (That's not the game's executable, it was the affiliate OverPro's adware executable.) Spysweeper's picking up the trace. The actual file minigolf_affiliate.exe is not in the package, neither is it's Wild Media accomplice WildApp.dll. Only placing a dead registry entry for the missing .exe remains.
Other files that sometimes came with that original adware aren't there either, like terabyte.exe, overpro323.exe, fixit.exe, blaster_blocks.exe, and no registry entries for any of those. If it contained any of those they would show up on running processes (CTRL+ALT+DEL, Processes tab) whether the game was running or not, they don't. Even if the game is running they're not there, only minigolf.exe which is the game's executable and is harmless.
I deleted the dead registry entry for minigolf_affiliate.exe, rebooted and reran Spysweeper and it came up clean and the game still runs fine. In the original infected file the game would no longer open once the adware was deleted. Not so in this one because the adware isn't there, just the trace. For some reason Spysweeper picks up the trace but can't clean the dead registry entry, so I did it manually. I am not going to post instructions on how to do that, anybody who already knows how doesn't need instructions. Anybody who needs instructions shouldn't be playing with registry and should just uninstall the game. It isn't that great anyway, bad camera angles.
