in the past 1 week, i have been facing high CPU usage issue in some computers. When they connected to our network, their CPU usage get %100. Then i disconnect from the network and connect to other internet like 4G/LTE Hotspots, It gets normal like %0-1. I didn't get whats going on in my network. We have a Guest WiFi in our network. This WiFi works in different VLan. When I connect to that WiFi it gets normal too.
Please help me about this.
