Microsoft Malicious Software Removal Tool 5.22
The Microsoft Malicious Software Removal Tool is an anti-malware utility that checks computers running Windows 10 Technical Preview, Windows 8 and Windows 8.1, Windows 7, Windows Vista, Windows XP*, Windows Server 2012 R2 and Windows Server 2012, Windows Server 2008, and Windows Server 2003 for infections by specific, prevalent malicious software—including Blaster, Sasser, and Mydoom—and helps remove malware and any other infections found.
When the detection and malware removal process is complete, the tool displays a report describing the outcome, including which, if any, malware was detected and removed.
The Malicious Software Removal Tool will continue to be provided for Windows XP through July 14, 2015; it will also continue to be delivered automatically via Windows Update and for download via the Download Center.
Note: The version of the tool delivered by Microsoft Update and Windows Update runs in the background and then reports if a malware infection is found. To run this tool more than once a month, use the version on this web page or install the version that is available at the Microsoft Download Center.
Because computers can appear to function normally when infected, it’s a good idea to run this tool regularly even if your computer seems to be fine. You should also use up-to-date antivirus software, such as Microsoft Security Essentials, to help protect your computer from other malware. Windows 8.1 includes antivirus and antispyware software called Windows Defender. Windows Defender for Windows 8 and Windows 8.1 replaces Microsoft Security Essentials.
