What is the purpose of Windows Defender?

Windows Defender is a built-in security feature provided by Microsoft in the Windows operating system. Its primary purpose is to protect the computer from various types of malicious software, including viruses, worms, ransomware, and spyware. It continuously monitors system activity and scans files in real-time to identify and neutralize potential threats before they can cause harm.

By providing this layer of security, Windows Defender helps to maintain the integrity of the operating system and safeguard user data from unauthorized access or damage. The effectiveness of such a security tool is critical as cyber threats continue to evolve, making it essential for users to have reliable protection against these dangers.

The other options, while valid functions within computing environments, do not align with the specific role of Windows Defender. Optimizing system performance pertains to improving the speed and efficiency of the computer, managing device settings involves configuring various system aspects, and organizing files and folders relates to file management. None of these functions are the focus of Windows Defender, which is explicitly designed to combat malware and spyware.
