Windows Malicious Software Removal Tool review
A free Windows cleanup tool for selected malware families, not full antivirus protection.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Windows Malicious Software Removal Tool (MSRT) is a free Microsoft utility for Windows that detects and removes selected prevalent malware families. It is intended for post-infection cleanup, with quick and extended/full scan options, threat reporting, and the ability to reverse some changes made by detected malware. MSRT is not designed to replace full antivirus protection, so it suits Windows users who need a focused removal utility rather than a complete security suite.
MSRT fits the Windows ecosystem through Windows Update, Microsoft Update, and Automatic Updates. It can run automatically in the background through updates, while a standalone on-demand download provides another way to start a scan. Quiet mode supports automatic-update deployments, and command-line switches allow quiet operation, detect-only scans, extended scans, and automatic cleaning. These options make the tool practical for administrative workflows that need repeatable or less visible execution.
Its main trade-off is scope. MSRT focuses on specific prevalent malware families, so it is narrower than software intended for broad, ongoing threat prevention. It also does not provide quarantine, limiting how detected items are held or managed after discovery. Choose MSRT for free Windows cleanup, targeted remediation, and command-line control. Choose a broader security product instead when you need comprehensive antivirus coverage, wider threat detection, or quarantine-based handling.
