How to Clean Windows with the Malicious Software Removal Tool

The Microsoft operating system has a built-in disinfection tool that can automatically detect and remove the most common malware.

You may not have known this, but Windows includes the Malicious Software Removal Tool (also known as MSRT, for Malicious Software Removal Tool). Updated automatically on the second Tuesday of each month via Windows Update, this program basically runs in the background with every new version. Consequently, the most commonly encountered malware (viruses, trojans, and other worms) is, in principle, automatically removed, and changes that they might have made to Windows are usually restored.

Although this tool runs automatically every month, it does not replace Windows Defender, Windows’ own antivirus. In fact, MSRT must be used in addition to the classic antivirus. Why ? Simply because it targets very specific threats.

Also, if you suspect that your computer is infected with malware, you can start MSRT manually instead of waiting for the second Tuesday of the month to update and start automatically. Here’s how.

1. Open the Windows Malicious Software Removal Tool.

To open the software uninstaller, use the keyboard shortcut Windows + R, then in the Run window that appears, type mrt and click OK.


In the User Management window that appears, click Yes.

2. Run a scan
