Its a RealTek File that sends private information (Adware)

Although the cfgwiz.exe process is used by Norton Antivirus, it is not essential to its operation. It has been reported as using a large amount of system resources, so if you find it causes problems for your system you should terminate it.

RealTek Audio Driver
This file is installed with the driver for integrated audio on Gigabyte, ASUS and other mainboards. It provides the functionality to automatically pop-up a window when a new device (such as speakers or a microphone) is plugged into an input jack connected to the onboard audio. The audio will still function with this startup process removed, but you will loose the auto-detection functionality.
