Might this high usage be temporary, as would perhaps be found in the midst of a periodic full background scan, etc..?
(UVK has a "Kill all processes" option that might terminat whatever it is, or, alternatively, MS/SysInternal's "ProcessExplorer" should let you suspend/kill whatever tasks are spawning your errant/stubborn task)....
(Purely as points of reference, although a Defender scan may only use 12-15% cpu resources, a MalwareBytes scan, while active, hovers at 65-75% during the quick scan during those few minutes (on a 7700K, w/ 32GB of RAM)

Download and run Sysinternals' Process Explorer.
Double-click on the process name and select the Threads tab to see which thread is using the largest amount of CPU.
Also, enable the VirusTotal check in Process Explorer by clicking on Options > VirusTotal.com > Check VirusTotal.com

I have also been experiencing this problem with Avast, and it drives me nuts when my CPU fan runs at high speed as a result.
Your 26 June 2017 post above was very helpful, but I have a couple of questions which I hope you can possibly answer for me?
Are Windows 10 Defender and Microsoft Security Essentials effective enough to use only those programs and not use a third party anti-virus program like Avast?
I also have Avast Cleanup Premium on my computer, and I'm wondering if there is another program I can use instead of that, perhaps even an online cleaning/tune-up service?
Thanks for the help!

Ditch Avast cleanup, it seems like a lot of the extras (bloat) that Avast has been adding to their AV are either problematic, too expensive or both. Use Windows built in tools for cleaning, if you want to use a 3rd party cleaner try Ccleaner. I would stay far away from optimization/ tuneup programs.

Thanks, digmor crusher. I think I will do just that and uninstall Avast Cleanup Premium. When you say to use "Windows built in tools for cleaning," can you tell me a little more about that and how to go about it? Thanks, again!

Sure, if your using Windows 10, just go to Windows Administrative Tools , in there you will find "Disc Cleanup" and "Defragment and Optimize Drives" options.
You could also go here....Control Panel\All Control Panel Items\Security and Maintenance\Automatic Maintenance, there you can set maintenance to run daily, this would include software updates, security scanning and system diagnostics. I don't use this so not sure how useful it is.

Again, thank you! I'm already doing those things, and I have downloaded and installed the professional version of Ccleaner. Appreciate the help!

Some "classic clean-up software" such as "Ccleaner" are classified as "Useless" in this database because the Windows registry does not need any maintenance except if you are victim of a malware infection and because tweaking the windows registery does not speed up a computer at all. It does not mean that Cleaner and similar tools are not good for sweeping your harddrive and help to keep your privacy. Registry cleaners have been become social engineering products (e.g. Iobit Advanced System Care, CCleaner, Wise Registry Cleaner, etc.) and paying for this particular function is just a waste of money
