Microsoft Safety Scanner is a free, on-demand virus and malware scanning tool provided by Microsoft. It detects and removes malware, spyware, and other security threats without requiring installation. Unlike real-time antivirus software, Microsoft Safety Scanner only works when manually executed and expires after 10 days, requiring a fresh download for future scans.

Why Use Microsoft Safety Scanner?

Microsoft Safety Scanner is useful for:

  • Quick Malware Detection: Identifies and removes active viruses and threats.
  • On-Demand Scanning: Works without installation and can be used alongside your existing antivirus.
  • Standalone Security Check: Useful if your PC is acting suspiciously, even with antivirus installed.
