A:Answer Hi Lam, thank you for the question. This laptop is TPM enabled. Windows Defender is the built-in virus protection in Windows 11. You can use other software, such as McAfee Live Safe - a 30-day trial is included with this laptop. A TPM (Trusted Platform Module) is used to improve the security of the PC. It's used by services like BitLocker drive encryption, Windows Hello, and others, to securely create and store cryptographic keys, and to confirm that the operating system and firmware on the device are what they're supposed to be, and haven't been tampered with.
