Key Features of Microsoft Defender Antivirus

1. Real-Time Protection

Microsoft Defender Antivirus can continuously monitor your computer for suspicious files, programs, and activities. Real-time protection helps identify potential threats while you are using your computer.

This can be especially useful when opening downloaded files, installing applications, browsing websites, or accessing external storage devices.

2. Quick, Full, and Custom Scans

Windows Security provides different scanning options depending on how thoroughly you want to check your PC.

• Quick Scan: Checks common locations where threats are likely to be found.
• Full Scan: Examines files and running programs throughout the computer.
• Custom Scan: Allows you to choose specific files or folders to scan.
• Microsoft Defender Offline Scan: Restarts the computer and performs a scan outside the normal Windows environment, which can help identify persistent threats.

If you suspect that your computer may be infected, a Full Scan or Offline Scan can provide a more thorough security check.

3. Cloud-Delivered Protection

Microsoft Defender uses cloud-connected security intelligence to help identify newer and emerging threats. Along with traditional malware detection, Microsoft's protection technologies can use behavior monitoring, machine learning, and cloud-based intelligence to improve threat detection.

Keeping cloud-delivered protection enabled can help Windows respond more effectively to newly identified security threats.
