How to Run Microsoft Windows Malicious Software Removal Tool


The Microsoft Windows Malicious Software Removal tool was created by Microsoft for Windows users to remove pesky software that has been installed on their computer. While the tool itself is rather easy to use, sometimes downloading it and actually getting the tool up and running is tricky. Following a few steps will enable you to easily run the tool and remove the software you need to remove.

  • If you don't have it already, download the Malicious Software Removal Tool by visiting the link in the “Resources” section of this article. Double-click the executable and follow the on-screen prompts to install.

  • Click “Start > Run.” Type in “mrt.exe” minus the quotes. Click “OK.”

  • Click “Continue” when prompted to by User Account Control.

  • Click “Next” to move forward in running the tool.

  • Click “Quick Scan” and then click “Next.” Alternatively, you can click “Full Scan” to run a more complete, longer scan. You can also click “Customized Scan” to customize what the tool scans for, an option that's best suited for advanced users.

  • Wait for the scan to complete, which can take up to an hour

  • In the results box that pops up after the scan is complete, click “Remove” and then “Next” if the tool has found malicious software, which it will then delete. If it hasn’t, click “Finish.”

Tips & Warnings

  • Run the tool at least once a week to keep your computer from getting infected any worse--and, in some cases, prevent infection all together.
