Telos: thank you very much for making the point about the Intel Management Engine. In this case, there was nothing related to it in BIOS, so disabling in Device Manager seemed like a temporary stop-gap. The Intel service is no longer showing up in Services.msc and Task Manager but no matter, it needs further investigation. Absolutely will follow up on this, I sort of forgot about it.
As for DUMo or any driver updater, I do a scan only. I never use the utility to update for me. When DUMo claimed there were chipset updates available, there were actually none specifically for my machine via Intel's website. I don't take risks when it comes to hardware. If my device throws no warnings in Event Viewer, there are no vulnerabilities reported for the current drivers ,and the machine runs fine, I don't pursue it. NVIDIA, I have to play with oftentimes but that's it. Mind you, I speak for myself cuz many use this software successfully. It can be very convenient.
Edit: After running an
Intel tool for the IME to see if the backdoor vulnerability was still there, this was the outcome:
Does anyone remember when this disclosure about Intel's Management Engine was first made? That, Sprectre, Meltdown, it's something to be vigilant about, for sure.
