After extracting this game and running unpack.exe I immediately get a virus notification. Apparently, unpack.exe is infected by Trojan.Blakhal.b
I would like to restate that this virus resides in the Proper version of Kingpin uploaded by dead-meat.
Jaja...I had the same alert made by Avast Antivirus.
Solution: you must deactivate your antivirus before click on unpack.exe, later when unpack.exe begins to unpack, you can activate again your antivirus.
