Microsoft Safety Scanner is a free, portable malware removal tool from Microsoft designed to help detect and remove malicious software from Windows computers.
Unlike a traditional antivirus program, Safety Scanner does not provide real-time protection or automatic background monitoring. Instead, it is an on-demand scanner that users can download and run manually when they want to check a Windows PC for malware.
The tool is particularly useful as a second-opinion scanner when you suspect that a computer may be infected or want to perform an additional malware check alongside your existing security software.
Key Features
On-Demand Malware Scanning: Manually scan a Windows computer for known malware and other malicious software.
Malware Removal: When supported threats are detected, the tool can attempt to remove them from the system.
Portable: Microsoft Safety Scanner does not require a traditional installation. Download the executable and run it directly.
Multiple Scan Options: Choose from available scan types depending on how thoroughly you want to check the system.
Regularly Updated: New versions are released with updated malware detection capabilities. Microsoft recommends downloading the latest version before running a scan.
Temporary Tool: The downloaded executable is intended for short-term use and does not function as a permanent security application.
How It Works
Microsoft Safety Scanner is designed as a supplementary malware detection and removal tool.
After downloading the latest version, launch the executable and select a scan type. The scanner checks the system for supported malware and displays the results after the scan is completed.
If threats are detected, the tool provides information about the findings and attempts to remove supported malicious software.
Because Safety Scanner does not provide real-time protection, it should be used together with a full-time antivirus or endpoint security solution rather than as a replacement for one.
How to Use
- Download the latest version of Microsoft Safety Scanner.
- Run the downloaded executable.
- Accept the applicable terms and follow the instructions.
- Select the desired scan type.
- Start the scan and wait for it to complete.
- Review the scan results.
- Follow the recommended actions if malware is detected.
The tool can be removed simply by deleting the downloaded executable when it is no longer needed.
Important Notes
Microsoft Safety Scanner is not a replacement for antivirus software.
It does not provide continuous real-time protection, automatic background monitoring, or the complete security features normally found in a dedicated antivirus product.
Also, each downloaded version of Safety Scanner is valid for 10 days from the time it is downloaded. For the latest malware definitions and detection improvements, download a fresh copy before performing a new scan.
