How Do I Run Windows Malicious Software Removal Tool? A Comprehensive Guide
The Windows Malicious Software Removal Tool (MSRT) is a free utility from Microsoft that helps remove prevalent malicious software from computers running Windows. To run it, you simply need to download it through Windows Update or directly from Microsoft, and then follow the on-screen prompts for a quick or full scan, proactively safeguarding your system.
What is the Windows Malicious Software Removal Tool?
The Windows Malicious Software Removal Tool (MSRT) is a powerful yet straightforward utility designed to detect and remove specific, prevalent malicious software from Windows computers. Unlike a full-fledged antivirus program that provides continuous protection, the MSRT is run on-demand.

Using the Windows Malicious Software Removal Tool offers several advantages:
- Free of Charge: Microsoft provides the MSRT completely free to all Windows users.
- Ease of Use: The tool is incredibly user-friendly, requiring minimal technical expertise.
- Regular Updates: Microsoft updates the MSRT monthly to target the latest threats.
- Complements Existing Antivirus: It works alongside your primary antivirus software, providing an additional layer of security.
- No Installation Required: It doesn’t require a traditional installation process. You simply run the executable file.
- Removes Specific Threats: It focuses on removing specific, widespread malware strains.

Understanding Scan Types
Choosing the right scan type is crucial for effective malware removal.
| Scan Type | Description | Speed | Thoroughness |
|---|---|---|---|
| Quick Scan | Scans the most common locations where malware resides, such as system folders and program files. | Fast | Less |
| Full Scan | Scans the entire system, including all files and folders. | Slow | More |
| Customized Scan | Allows you to select specific folders to scan. Useful if you suspect malware is located in a particular area. | Variable | Variable |
Common Mistakes to Avoid
While running the MSRT is generally straightforward, here are a few common mistakes to avoid:
- Skipping Updates: Always ensure you have the latest version of the MSRT to detect the newest threats.
- Relying Solely on MSRT: The MSRT is not a replacement for a comprehensive antivirus solution. Use it as a supplemental tool.
- Interrupting Scans: Avoid interrupting the scan process, as this may prevent the MSRT from properly removing malicious software.
- Ignoring Results: Pay close attention to the scan results and take appropriate action if malware is detected.
- Downloading from Unofficial Sources: Only download the MSRT from the official Microsoft website to avoid downloading fake or malicious versions.
Frequently Asked Questions (FAQs)
Is the Windows Malicious Software Removal Tool a replacement for an antivirus program?
No, the MSRT is not a replacement for an antivirus program. It’s a supplemental tool designed to remove specific, prevalent threats. An antivirus program provides continuous protection and real-time scanning, while the MSRT is run on-demand to address existing infections. You should always have a robust antivirus solution installed and keep it updated.
How often should I run the Windows Malicious Software Removal Tool?
While the MSRT typically runs automatically with Windows Update, it’s a good practice to run it manually every month, especially if you suspect your computer may be infected. This provides an extra layer of security beyond your primary antivirus software.
Does the MSRT slow down my computer?
During a scan, the MSRT can consume system resources and potentially slow down your computer. However, this slowdown is usually temporary and depends on the scan type and the size of your hard drive. A quick scan has minimal impact, while a full scan can take considerably longer and use more resources.
What should I do if the MSRT finds malicious software?
If the MSRT detects malicious software, it will attempt to remove it automatically. Follow the on-screen prompts to complete the removal process. After removal, it’s recommended to run a full scan with your primary antivirus software to ensure that all traces of the malware have been eliminated.
How do I know if the MSRT has already run on my computer?
You can check the MSRT log file to see if it has run and the results of the scan. The log file is located in the %windir%debug directory and is named mrt.log. You can open this file with Notepad to view the scan history.
Where can I download the Windows Malicious Software Removal Tool?
You can download the MSRT from the official Microsoft website. Search for “Microsoft Malicious Software Removal Tool download” in your preferred search engine, or navigate directly to the Microsoft Download Center. Be extremely cautious about downloading the MSRT from any other source.
What if the MSRT fails to remove the malicious software?
If the MSRT is unable to remove the malicious software, it may indicate a more complex infection. In this case, it is recommended to run a full system scan with your primary antivirus software. If the problem persists, consider seeking professional help from a computer security expert.
How do I know which version of the MSRT I need to download (32-bit or 64-bit)?
To determine whether you need the 32-bit or 64-bit version of the MSRT, check your Windows system type. Go to Settings > System > About. Under “System type,” you will see whether you are running a 32-bit or 64-bit version of Windows.
Is the MSRT available for older versions of Windows?
The MSRT is typically available for supported versions of Windows. However, Microsoft may discontinue support for older operating systems, which could affect the availability of MSRT updates. Check the official Microsoft website for the latest compatibility information.
Does the MSRT collect my personal information?
According to Microsoft, the MSRT does not collect personally identifiable information. However, it does send anonymized information about detected malware to Microsoft to help improve the tool’s effectiveness and protect other users.
Can I run the MSRT in Safe Mode?
Yes, you can run the MSRT in Safe Mode if you suspect a severe malware infection. Safe Mode starts Windows with a limited set of drivers and services, which can help prevent the malware from interfering with the scan. To enter Safe Mode, restart your computer and press the appropriate key (usually F8 or Shift+F8) during startup.
How Do I Run Windows Malicious Software Removal Tool? on a Schedule?
While the primary functionality is on-demand, you can technically schedule the MSRT using the Windows Task Scheduler. Create a new task, point it to the mrt.exe executable, and set your desired schedule. However, keep in mind this doesn’t replace real-time antivirus protection and should be supplementary.
