Which of the following aids in the overall security of your computer by warning you before running unrecognized apps and files downloaded from the Internet?

A) Control Panel
B) Windows Defender SmartScreen
C) User Account Control
D) Security & Maintenance

Windows Defender SmartScreen is specifically designed to warn users about unrecognized apps and files downloaded from the internet, thereby enhancing the overall security of the computer. Control Panel is a configuration tool that allows users to manage various system settings. User Account Control provides a way to limit the privileges of programs to prevent unauthorized changes to the system. Security & Maintenance is a feature introduced in Windows 8 and later versions that provide alerts and notifications about security-related issues on the computer. However, none of these options specifically address warning the user about unrecognized apps and files downloaded from the internet.
