It's the driver for the Realtek High Definition Audio card. It is indeed harmless, but commonly installed incorrectly, causing problems. I'm not sure if your sound will work without it.

It is part of the HD Audio Package from Reatek & Asus. Not every Audio version requires it, depending on the Drivers required for your motherboard. Open your setup package, if it is included you need it.
