MFA (Multi-Factor Authentication) is a security measure that often uses an SMS or third-party application as a secondary method to access a system. MFA requires the user to provide two or more pieces of evidence to prove their identity, such as something they know (e.g., password), something they have (e.g., phone), or something they are (e.g., fingerprint)2. WPA2 (Wi-Fi Protected Access 2) is a security protocol for wireless networks that does not use SMS or third-party applications. AES (Advanced Encryption Standard) is a symmetric encryption algorithm that does not use SMS or third-party applications. RADIUS (Remote Authentication Dial-In User Service) is a network protocol that provides centralized authentication and authorization for remote access clients, but does not use SMS or third-party applications.

Screen lock is a feature that returns a computer to the login screen after a period of inactivity, requiring the user to enter their credentials to resume their session. Screen lock can be configured using Group Policy settings, such as Screen saver timeout and Interactive logon: Machine inactivity limit. Screen lock can help prevent unauthorized access to a computer when the user is away from their desk. Login times are not a feature that returns a computer to the login screen, but a measure of how long it takes for a user to log in to a system. User permission is not a feature that returns a computer to the login screen, but a set of rights and privileges that determine what a user can do on a system. Login lockout attempts are not a feature that returns a computer to the login screen, but a security policy that locks out a user account after a number of failed login attempts.  https://wosh ub.com/windows-lock-screen-after-idle-via-gpo/

Drilling and incinerating are physical destruction methods that make the data on hard drives unrecoverable. Standard formatting, erasing and low-level formatting are logical methods that can be reversed with data recovery tools. Recycling is not a destruction method at all.

The best explanation for why the system still has malware after performing a System Restore is that the malware was installed before the system restore point was created. A system restore point is a snapshot of the system settings and configuration at a certain point in time. A System Restore is a feature that allows users to restore their system to a previous state in case of problems or errors. However, a System Restore does not affect personal files or folders, and it may not remove malware that was already present on the system before the restore point was created. A system patch disabling the antivirus protection and host firewall may increase the risk of malware infection, but it does not explain why the malware persists after a System Restore. The system updates not including the latest anti-malware definitions may reduce the effectiveness of malware detection and removal, but it does not explain why the malware persists after a System Restore. The system restore process being compromised by the malware may prevent a successful System Restore, but it does not explain why the malware persists after a System Restore.
