I have been looking through my services and noticed a service called "AtherosSvc" which has no description. It struck me as odd, as it is one of 10 services with no description, however all the others I know exactly what they are and what they do from their name. I did a quick google search and found that some sites called it a trojan, others said it was safe, and yet others said it was required for windows to function properly.

I am looking to know if AtherosSvc is safe and if it is, what does it do?

Details about the service:

  • Path to executable: C:\WINDOWS\system32\AdminService.exe
  • Startup type: Automatic
  • Log on as: Local System account
  • If this service fails: Take No Action
  • Dependencies: None
  • Simple question, do you have an Atheros device, installed in your system? – Ramhound Feb 19 '19 at 5:03
  • I believe I have a Quallcomm QCA61x4A Wireless Network Adapter. – Trenly Feb 19 '19 at 22:31
  • Atheros is owned by Qualcomm. So have you tried to remove the software that uses the service in question? – Ramhound Feb 19 '19 at 22:43
  • The thing is, I have no idea what is using the service. That is why I came here – Trenly Feb 20 '19 at 5:26
  • You have not supplied enough information for us to identify what installed the service. However, it’s connected to your, Quallcomm device that much is clear – Ramhound Feb 20 '19 at 12:50

My research indicates that it is a Bluetooth driver for motherboards with built-in Bluetooth. However, most sites indicate that it should be found at %ProgramFiles%\Bluetooth Suite\adminservice.exe. The fact that yours is in C:\Windows\System32 might mean that it is not a legitimate version.

If you are not using any Bluetooth features, it won't hurt anything to disable the service.

  • I think it is interesting that I don't even have a Bluetooth Suite folder in my Program Files or Program Files (x86). I do use some Bluetooth features occasionally but not all that often. I'll try disabling it for a little bit and see if I notice any loss in functionality – Trenly Feb 19 '19 at 22:33

I have a couple of Dells and on both PC's AtherosSvc is loaded from: C:\WINDOWS\System32\drivers\AdminServioce.exe

Looking at the properties of the exe...you can see the signiture. enter image description here

For peace of mind...
Open Control Panel->Programs and Features
If you click Qualcomm WLAN and Bluetooth Client Installation you will be presented with a dialog box to repair the installation.
