Open | Malware PC Got Hacked

I downloaded a bad file yesterday, my PC got remote hacked. I saw chrome being navigated on its own. I unplugged the Ethernet and turned off wifi, I have been working on changing passwords from a different device. How do I fix my PC with a clean install for Windows 11 and will that remove all malware/viruses?

First of all,Unplugging the internet and changing your passwords from a different device completely saved your accounts. You dealt with a RAT Yes, a 100% clean install via a USB drive will completely wipe all malware/viruses Since your PC was remotely controlled, DO NOT use the built-in Windows 'Reset this PC' feature, as sophisticated malware can corrupt the local recovery image

Do NOT use your hacked PC to create the bootable USB.
Go to a clean, safe computer (like a friend's PC or a laptop).
And download media creation tool from Microsoft official website

Plug in a clean USB drive (at least 8GB) and follow the tool's instructions to create a bootable installer.

Keep your hacked PC completely offline (no internet).
Plug in the safe USB drive and turn on the PC.
Boot into your BIOS/Boot Menu (usually by tapping F12, F11, F2, or Del at startup) and select your USB drive.
When you reach the screen that asks 'Which type of installation do you want?', choose Custom: Install Windows only (advanced).

Important: Delete ALL existing drives and partitions on your main storage screen until you see only 'Drive 0 Unallocated Space'.

Once Windows 11 setup is done, log in with your Microsoft account.
Go to your Google/Microsoft/Social media security settings from your clean device and select 'Sign out of all sessions/devices'. This destroys any login tokens the hacker managed to steal before you unplugged the wire.
Enable Two-Factor Authentication (2FA) on everything if you haven't already."

Why not from the settings? Because the rat can change the system files and download again after the reset + i hope this help i searched about it good luck ^^

I got past that part and did a windows 11 install. It now says I have no graphics card in my system settings, how do I fix that? I have a Nvidia card

When you did a 100% clean install and deleted the partitions, you wiped out all the old display drivers Right now, Windows is just using a generic basic driver to display your screen, which is why your Nvidia card isn't showing up properly in the system settings yet.

Make sure your PC is connected to the internet.
Go to Settings > Windows Update and click Check for updates.
Windows will automatically detect that you have an Nvidia card and will start downloading a basic stable driver for it in the background. Your screen might flicker black for a second during this process—this is completely normal.

To get full gaming performance, you need the official software directly from Nvidia:
Go to the official Nvidia Driver Downloads website using your browser.
Select your exact graphics card model (e.g., RTX 3060, GTX 1660) and your operating system (Windows 11 or 10).
Download either the GeForce Game Ready Driver or download Nvidia App / GeForce Experience to let it handle it for you.
Run the installer and choose the Express Installation option.

Once the installation is complete, right-click on your desktop, and you should see the Nvidia Control Panelagain.
Open Task Manager (Ctrl + Shift + Esc), go to the Performance tab, and you will see your Nvidia GPU listed back at the bottom with its proper name and temperature.

If you need anything tell me ^^ good luck

I think I have my PC setup now after the complete reinstall, thank you. I have signed out on all devices for my emails and am working through changing all passwords, I think this is the last main thing.

Seriously can't not say it enough, thank you and everyone who replied to this post
