None of the solutions can do that all of the time especially on something labelled as a "zero-day" issue.
So, you may find something that rids your computer of the infection only to find that the infection returns as soon as you reboot or run that great program you found.
Since you control what you download , how can you expect an AV program to stop it ?
Anti Virus means just that, it's not Anti Malware .
I have three grandsons with HP's and after that affair, Norton's was put on theirs also. I used Windows Defender on my grandsons' laptops because it was free and I figured Windows was dependable. It was worth the money.downloading malware/adware on our PC.
Genius Box is a browser extension that was probably bundled into another program that you "clicked Yes" on .
Check function with programs that do not use the internet to help isolate the issue, if there are no freezes or dropout playing videos that are not fed from internet sources, the chances of it being hardware are less.
If it is slow to boot and run local programs it could be slow hard drive access (a common failure mode that passes many hardware tests).
If you need help with it, go to the hp website and ask the question based on your computer.
Hope this helps I would recommend that you use AVG for a free program.
My grandson had malware/adware on his computer called Genius Box.
