Any way to trick Steam into thinking the game is running?

[sosoqudah]

I've got a smurf account that I subtly hack on, it's good and all, but people see my hours and are automatically suspicious. I've been running the game on my second computer for about 100 hours now, but it's using up a lot of resources on a computer that's just supposed to be a server to host my website, game servers, etc., so I really can't keep it open anymore. Steam Achievement Manager and Idle Master had a thing where it could trick Steam into thinking the game is currently being run, without having to use up resources to run the game. Is there any way I can get that in .bat form or a simple program so I can run CS:GO on my second computer without having to use a lot of resources?
