Microsoft Safety Scanner is a free computer scan tool designed to locate and remove malware from Windows computers. This portable, on-demand scanner provides a quick and easy way to check for and address potential threats without requiring a paid subscription.
How Microsoft Safety Scanner Works
The Safety Scanner works by comparing files and processes on your computer against a database of known malware signatures. This database is regularly updated to reflect the latest threats. When a scan is initiated, the tool thoroughly examines your system, identifying any potential malicious software. If malware is found, the Safety Scanner attempts to remove it and reverse any changes made by the identified threats.
Key Features of Microsoft Safety Scanner
- Free of Charge: The scanner is completely free to download and use.
- On-Demand Scanning: It only scans when manually triggered, giving you control over when to check your system.
- Portable Executable: No installation is required. You download the executable file and run it directly.
- Latest Definitions: While the tool itself expires after 10 days, each download ensures you have access to the most up-to-date malware definitions.
- Multiple Scan Types: Choose from different scan types, allowing you to tailor the scan to your specific needs and concerns.
- Detailed Log: A comprehensive log file (%SYSTEMROOT%debugmsert.log) provides detailed information about detected threats.
Using Microsoft Safety Scanner
Using the Safety Scanner is straightforward:

Microsoft Safety Scanner vs. Antivirus Software
It’s important to note that Microsoft Safety Scanner is not a replacement for real-time antivirus software. It’s a complementary tool for on-demand scanning. A comprehensive security solution like Microsoft Defender Antivirus provides continuous protection and automatic updates to defend against emerging threats.
The Safety Scanner is a valuable tool for periodically checking your system for malware, particularly if you suspect an infection. Its free availability and ease of use make it an accessible resource for maintaining computer security. However, for ongoing protection, relying on a robust antivirus program is crucial. For assistance with persistent malware issues, consult Microsoft’s resources on removing difficult threats.
