Firmware rootkits invalidate this assumption entirely. When malware lives in the SPI flash on the motherboard — below the operating system, below the bootloader, below any software security control — no OS-level remediation is sufficient. The infection survives a Windows reinstall, a Linux install over Windows, a full drive replacement, and even a BitLocker wipe. The only remediation is reflashing the firmware from a trusted image or replacing the motherboard.</p>
