On Windows 10, the Microsoft Safety Scanner (MSERT) is a standalone tool that scans, finds, and removes many malware types, including viruses, spyware, and unwanted software causing harm on your computer without having to install it on the device.
The security tool is similar to the Malicious Software Removal Tool (MSRT), and it works similarly to a regular anti-malware software you use on Windows 10. It even has the same engine and threat definitions as the Microsoft Defender Antivirus. However, it is not a replacement for your antivirus solution since it does not offer real-time protection or automatic updates. Instead, it only provides another way to scan and remove infections when you suspect that your security software is not working correctly and believe the device has been infected.
Also, the Microsoft Safety Scanner is only valid for ten days. Once it expires, you need to download an updated version to make sure you are scanning the device with the latest security threats definitions and enhancements.
In this Windows 10 guide, we will walk you through the steps to scan and remove malware infecting your computer using the free Microsoft Safety Scanner tool.
