Malware potentially surviving clean installs

[SheepShoop]

I'm having a pretty nasty issue with my computer, I downloaded something I shouldn't have on Discord and accidentally ran a token grabber, which attempted to steal my Discord and Google account, though that problem has already been fixed by now, what I need help with is something else, I don't know what it did but a few days after downloading it and assuming I deleted all remnants of it, my computer's memory skyrocketed to 100% in Task Manager and my storage was being used up for no reason, so I got a USB stick and clean installed Windows 11. I assumed it got rid of it, but options in Windows Defender kept randomly disabling themselves, and a couple days later, my memory is at 98% in Task Manager and 4 Gigabytes of storage are mysteriously used. I quickly got up and got my USB stick and did yet another clean install. Everything was fine for about a day when suddenly, the option to block potentially unwanted apps was turned off, so I do yet another clean install to not risk anything. I have not downloaded anything besides Malwarebytes, and today, I look and see that 2 options have disabled themselves in Windows Defender. I'm getting so fed up with this, I just want to use my computer normally again, I know this is entirely my fault for downloading something I shouldn't have, but I just want this to be over already, my computer's warranty ran out but I do not have the money to buy a new one. If you're curious of how I'm doing the clean install, I'm going to UEFI Settings, boot menu, running the USB, and deleting all partitions, afterwards I setup the computer normally, and am not running any back ups.

Hi:

Doing a clean install should normally fix any problems with the OS.

I recommend that you make a bootable USB recovery drive with the HP cloud recovery tool that will reinstall W10, the drivers and the software that originally came with your notebook.

Here is an info link for how to use the utility.  You will need a 32 GB USB flash drive for this.

After you make the recovery media, boot from your W11 installation flash drive and clean the disk.

That goes beyond deleting the partitions.

After diskpart has cleaned the disk, you can exit out of the program, shut down the PC, remove your W11 installation flash drive and recover your PC with the cloud recovery tool media you created.

I'm currently running on Windows 11, should I still be fine running these tools as it seems they are for Windows 10, sorry if this is a dumb question to ask O just want to be sure.

If you use the media creation tool to reinstall W10, you can upgrade back to W11 by clicking on the blue W11 Installation assistant button at the link below (1st option) to upgrade to W11.

Download Windows 11 (microsoft.com)

Or if you would prefer, clean the disk first as shown in the video with your W11 installation media and then clean install W11 again,
