I have Glasswire Pro on my Windows desktop. Every week or so, a process called “Service Host: Local Service (No Network) (3)” will begin using tons of CPU time. Windows Defender Firewall is one of its three sub-processes, which is why I suspected GlassWire. Sure enough, when I kill the GlassWire Control Service, the process stops using CPU. I have also been able to stop the process by resetting Windows Firewall to default settings, but I do not want to do that every week.
I have also tried reinstalling GlassWire. Does anyone have any suggestions?
