If you want to run MSRT manually, you canĭownload the tool from Microsoft.

The results of the latest MSRT scan are always added to the mrt.log file, which is stored in a subfolder called Debug in your Windows directory. You dont have to worry about running the tool manually, although you can. The only trace of MSRT you can find on a computer is the MSRT log file. All you need to do is ensure the update is installed from Windows Update. This directory is automatically deleted after the tool finishes running or the next time that you start the computer.

This directory contains several files, including the MSRT executable, Mrtstub.exe. When it runs, it creates a randomly named temporary directory on the root drive of your computer. The tool always runs in quiet mode unless it finds an infection-if you aren’t notified of an infection, it means that MSRT hasn’t found any malicious software that needs your attention. When Automatic Updates are enabled, your computer automatically downloads and executes MSRT on a monthly basis. Alternatively, you can download the Windows Malicious Software Removal Tool. If a confirmation message appears, click OK again. An easier way is to type mrt.exe in the Start Menu Search Box or in the Run window. MSRT can’t run on machines with older OSs. Right-click Start, select Run (or Windows key +R) Type msiexec.exe /unreg and click OK. MSRT runs not only on Vista, but also on Windows Server 2003, Windows XP, and Windows 2000. What few people know is that your computer automatically downloads and runs MSRT when you’ve enabled Automatic Updates.
