how can I completely erase potential infostealer in my pc?

Hii, I think I might have reluctantly completed a sketchy captcha through a pirate streaming website yesterday, but didn't think much of it until this morning, after being warned via email that there was some suspicious activity happening in my discord account.

Upon login, I realised it had been used to spread that Mr. Beast screenshot scam that has been happening a lot lately.

Shortly after, I was notified they got into my Epic Games account too, and later today they also got an old facebook account, all of them connected by the same email.

I disconnected my pc from internet connection as soon as I could and made sure to change passwords and log off of everything important using a safe device.

I can still run a scan using malwarebytes, however the access to windows security center has been limited "Your IT administrator has limited access to some areas"...

I'm currently backing up some documents into a USB driver in order to proceed with either a reset or whatever might be the best/only solution in this case.

Is there something else to be done to fix this? If someone could provide some guidance on what to do from now, that would be great.

Thank you so much!!

You must reinstall from a USB that you create on another PC.
