• Real-time protection: Windows Defender runs in the background, monitoring your device's activity in real-time to detect and prevent malware attacks.

• Cloud-based detection: The software uses Microsoft's cloud-based servers to update its malware signatures and improve detection rates.

• Regular scanning: Windows Defender performs regular scans of your device's files and programs to identify potential threats.

Common questions
