Is your processor going for full when you come back to your computer after a coffea?
Does your CPU max out as soon as you use a full screen application or try to relax and watch a movie?
Then you might have a miner software parasitizing your system's resources.
Nasty little piece of software that runs when your system is idle, or you are not at your computers.
They like to hide as soon as you try to see what is running.
This application is a project that will try and help you discover if a miner or other software is parasitizing your system.
