Microsoft Defender serves as the primary guardian of Windows systems, adeptly identifying and neutralizing emerging threats. Yet, alongside this robust defense lies a lesser-known yet remarkably effective tool: the Malicious Software Removal Tool (MSRT). This unassuming utility is designed to target prevalent malware, focusing on comprehensive remediation rather than merely detection.
What is the Malicious Software Removal Tool
In conjunction with Microsoft Defender, the Malicious Software Removal Tool stands as an additional line of defense against malware. Updated monthly through Windows updates, MSRT operates in Quiet Mode during these updates, scanning for the most common malware infections, including various families of trojans, rootkits, and worms.
Each monthly update enhances MSRT’s capabilities by adding new malware families to its detection list while removing those that are no longer prevalent. Upon identifying an infection, MSRT not only eliminates it but also strives to reverse any malicious alterations made to the system.
While it does not replace the comprehensive threat detection offered by Microsoft Defender, MSRT serves as a valuable backup solution, adept at catching high-risk threats that may arise during a specific timeframe. Notably, it can function alongside third-party antivirus software, ensuring that users benefit from a Microsoft-backed solution even when other antivirus programs are in play.
When to Use the Malicious Software Removal Tool in Windows
The question often arises: why utilize MSRT when Microsoft Defender and other antivirus solutions already provide robust protection? Here are several scenarios where the Malicious Software Removal Tool proves particularly beneficial:
- Use MSRT alongside a third-party antivirus: For those employing third-party antivirus programs, integrating MSRT can enhance security. Given that third-party solutions maintain their own virus definitions, MSRT may identify threats that other software overlooks.
- MSRT can undo changes made by malware: While standard antivirus programs typically focus on deleting detected malware, MSRT is specifically engineered to remove and rectify damage inflicted by adware, infostealers, and trojans. It can eliminate harmful extensions, reset browser settings, and restore various system changes, making it an invaluable tool for post-infection cleanup.
- Works even when security tools are compromised: Many malware variants are designed to disable antivirus software, rendering them ineffective. As a standalone security tool, MSRT often remains unaffected by such attacks, allowing users to run it to potentially identify and eradicate the underlying threat.
How to Use the Malicious Software Removal Tool in Windows
By default, MSRT runs monthly and only reports findings when it detects known malware infections. However, users can also initiate a scan on demand for an additional layer of assurance.
To launch MSRT, press Windows + R to open the Run dialog, then type mrt and confirm the User Account Control (UAC) prompt.
Upon opening, click Next to select your preferred scan type, which includes Quick, Full, and Customized scans. The duration of the scan will vary, with a full scan potentially taking several hours. Choose the scan that best fits your needs and proceed by clicking Next.
As the tool scans your system, it will automatically take action against any detected infections, working to remove them and restore any damage caused. After the scan concludes, you can click on View detailed results of scan to review what was detected and the types of threats identified.
This report serves as an educational resource, offering insights into prevalent malware, including notorious names like Emotet, Neptune, and WannaCry. While MSRT is not a substitute for Microsoft Defender or other antivirus solutions, it acts as a supplementary security tool. For optimal protection, it is advisable to utilize MSRT in conjunction with other Windows security features.
