Atheros Client Utility may be installed under Program Files as part of support software for a wireless network adapter based on an Atheros chipset and may be marketed under any number of brand names. It will be running when your adapter is in use and should show be accessible via a 'WiFi bars'-type icon in the system tray. As such, it is probably required for normal operation of your wireless adapter, and is harmless. For support you need to contact the OEM or vendor of your device, not Atheros.
