What's your CPU?

Do you disable hardware acceleration on the browser?

Sounds a bit like a cryptocurrency mining malware disguising itself as your browser.


Does the correct application in the correct folder show up if you right click on the process in WIndows' task manager and select "Properties"?


Does the usage show up in the task managers of the browsers? It's accessible in both by opening the menu in the top right and going to "More tools" > "Task Manager" (interesting how it's the same steps in both), or by pressing Shift + Esc in Chrome. If it does show up, what tab or extension is using that much CPU?


Try a malware scan. Windows Defender is installed and activated by default on Windows, or you can try a third party software like Malwarebytes.
