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
This should open the Microsoft Windows Malicious Software Removal Tool window. Press “Next”.
The tool then offers three types of analysis: a quick one that analyzes folders most likely to be infected, a full one that performs a complete analysis of the machine (which can take several hours), and a personalized one that only analyzes the files you send. to that.
Select the analysis you think is necessary and click the “Next” button.
3. Check result
It should then run a scan that will show you in real time if any threats have been found. Once the scan is complete, the tool clearly indicates if a threat has been detected. If no threats were found, click Finish.
On the other hand, if the tool found one or more threats, you can click View detailed search results.
. After that, you will receive a list of malware that the utility was looking for, as well as those that it detected and removed. Click OK to close the window, then click the Restart button to restart your computer.
