How Windows Defender Works

Windows Defender is a built-in antivirus software that comes pre-installed on Windows devices. Its primary function is to scan files, folders, and programs for potential threats, such as viruses, spyware, and malware. The software works by using a combination of signature-based detection and behavior-based detection. Signature-based detection involves identifying known malware signatures, while behavior-based detection identifies patterns of behavior that may indicate a threat. This dual-layer approach ensures that Windows Defender can effectively detect and block various types of malware.
