I’ve run a few malware scans, but I’m still worried and want a clean start. Is Windows’ reset option enough, or should I reinstall from a USB drive? What should I do with my files and other drives?
What’s the safest way to wipe a Windows 11 PC if I’m worried about a keylogger?

For a thorough reinstall, use another trusted device to get Microsoft’s official Windows installation media, make a bootable USB, and start the PC from it. During setup, delete the partitions on the Windows drive and install Windows into the unallocated space. Be certain you have selected the right drive, since deleting partitions erases their contents.
Back up only files you need, not old programs or installers. Scan the backup before opening it on the fresh install, and reinstall applications from trusted sources. If you have other internal drives, disconnect them during setup if practical, then scan them before using them again.

Before wiping, pin down what triggered the suspicion. If the scans found nothing and there are no specific signs of account access or unusual behavior, a keylogger is only one possibility, and reinstalling may not answer what happened. Run reputable security scans, update Windows, and change important passwords from a separate, trusted device if you think credentials may have been exposed. Turn on multi-factor authentication where available.
If you do reinstall, keep the backup limited and be cautious with anything restored afterward. A reset or reinstall cannot clean a different infected device or make compromised online accounts safe by itself.

Quick version: back up essentials, make official Windows installation media, boot from it, remove the partitions on the target system drive, and install fresh. Don’t use a random “cleaner” tool, and don’t restore a full system image if your goal is a clean start.
Firmware-level malware is possible in principle, but it is not the usual explanation for a vague keylogger worry. I wouldn’t start changing BIOS firmware unless there’s concrete evidence or a specialist advises it.

Would the built-in reset with “Remove everything” be less thorough than reinstalling from USB?
G9~Tarnish:
A reset is simpler and is often adequate for ordinary malware concerns. A clean install from official media gives you a clearer fresh start, especially if you want to remove the existing Windows installation and partitions.
