Microsoft Windows Malicious Software Removal Tool (MSRT) is a freeware second-opinion malware scanner that Microsoft's Windows Update downloads and runs on Windows computers each month, independent of the installed antivirus software. First released on January 13, 2005,[2] MSRT does not offer real-time protection. It scans its host computer for specific, widespread malware, and tries to eliminate the infection. Outside its monthly deployment schedule, it can be separately downloaded from Microsoft.[3][1][4]
