Yeah, I figured as much as they're required processes which is why I'm asking how to diagnose this. In the past, I would just systematically go down the list of processes and disable 3rd party components until the system normalized. This doesn't seem to work in this particular case.
The following is a list the known 3rd party components currently running in the background:
3. SoftEther VPN
5. Intel Video
I've disable everything individually that I know of except for the Intel video compnents and the CPU Idle's still high. The 2 VPN components are relatively recent and the CPU idle was already high previous to their installations.
Also, to directly answer your 2 questions:
1. No other processes are using up any notable (>1%) CPU usage while idle. The 2 culprits I mentioned pretty much takes up the entire CPU usage.
2. No, I have not done a thorough AV scan of my device in over a month. Currently, the sole AV I have is the built in Defender. I do, however, keep my entire system updated.
Would it be satisfactory to just do a thorough scan with Defender? I ask because I've been on this site before for other malware fixes and I was always asked to do a whole series of tasks.
I'm using a stock HP 15-d035dx if that makes any difference.
Thanks again for your time Usasma.
