How To Use Windows Malicious Software Utility For Post Infection Removal On Windows 2000/XP/Vista


Microsoft Windows Malicious Software Removal Tool is basically a free tool which helps to remove specific malicious software from computers which run Windows operating systems, including all versions of Windows Vista. After it is installed, it silently runs in the background and removes the malicious software that it finds. When the detection and removal process is complete, the tool generates a report describing the outcome of the scan. It’s actually a free but basic anti-virus, anti-worm and anti-Trojan security utility that provided by Microsoft to protect and secure Windows Vista, Windows XP, Windows 2000 and Windows 2003 system by way of post infection removal.

Where To Find MRT.EXE

By default, the tool can be found in the C:\Windows\System32 folder. Once you open this location, search for a file called mrt.exe. If you don’t find this file, it means that this tool is not installed on your PC. In this case you can download it directly from the Microsoft Download Center. The 64 bit version can be found here.



How To Use It

After opening MRT.EXE, you’ll see the Welcome window, click Next.


Now you need to select the type of scan you want the tool to perform. You have three possible options: Quick scan, Full scan and Customized scan. If you did not scan your PC before and you don’t have a reliable antivirus solution installed, you might want to select Full scan. Once you selected the option you prefer, click Next.


It will start scanning your computer and show you the status of the scan. If malicious software has modified (or infected) user files on the computer, the tool will prompt you to remove the malicious software from those files. You can choose to clean specific files or all infected files found. Note that some data loss is possible during this process and that the tool may not be able to restore some files to the original, pre-infection state.


When finished you will see the results. In my case, no malicious software was detected. Now click Finish and the tool will close.


A few days back, my computer was infected by some virus which even corrupted my antivirus, firewall, registry editor etc, at that time this tool was my life saver, it may not be useful for everyone. The point of writing this post was that when everything fails to disinfect the virus in your computer, you can give this tool a shot.
