Is stdrt.exe a virus?

Not long ago, I downloaded Knytt Stories and booted it up. I had task manager up at the time, and I noticed that when I activate the game, it turns on two processes: the name of the game, and stdrt.exe. I googled it to see just what is up with that, and more importantly, to see if it's a virus. People say it is, but scanning both the Knytt Stories folder and using Malwarebytes quick scan showed no such virus. It helps that whenever I close Knytt Stories, stdrt.exe gets closed off too. I also downloaded this game straight from the source, so that further raises doubts about it being a virus.

So is it a virus? A false positive? Just paranoia?
