If it's a programme running that you don't know and possibly didn't choose to install, it's probably malware/ virus software. Try installing and running Malwarebytes- the free version at top of the list here-> https://www.malwarebytes.org/downloads/
It's easy to install and run, assuming you can still get to the internet while the alleged diagnostic programme is doing its thing. It was recommended elsewhere on here and has sorted me out a few times.

If not, might be worth taking it into a repair shop/resetting the computer.
