An unknown device appears

It sounds very good 3Colors.

I don't know what to tell you other than the issue "unknown device CPUZ###" has been addressed.

You ran a virus check and found nothing - you could run more, but ESET is fairly good. As long as you keep the virus definitions up-to-date and run regular scans - that's about the best anyone can do.

Hardware, probably not, some software has to emulate hardware drivers for them to provide their function - this is normal.

I'm 99.9999% certain it came from CPUID software (either HWmonitor or embedded in another Utility - Speecy uses CPUZ code or it did at one time... I think)

Look in device manager every few days for a week to see if anything gets recreated in the unknown device category, I don't think it will.

It is outside the scope of any forum to do a forensic investigation to determine the cause, there are just too many variables.

If you want to start a thread in the Security forum, people there can give you some help on scanning your system with trusted tools. Just let them know in your thread that you are concerned there MIGHT be something and that you'd like to get a clean bill of health. It would be helpful if you included a link to your post#40 so the member assisting you there can easily reference back to this thread.

As for this thread, I think it can be marked solved in a few days.

My pleasure working with you.
