If you do not want MSS to send any information to Microsoft, you can disable the MSS’s reporting component with the following registry key setting.Įarlier, Microsoft offered the Windows Live OneCare Safety Scanner which also performed additional tasks like PC clean-up, Tuneup, etc, and replaced it with this new Microsoft Safety Scanner. The reports sent to Microsoft include technical information about MSS, Malware found, and your computer, such as, MSS version number, file names, cryptographic hash, size, date stamp, and other characteristics of any Malware removed from the computer, the success or failure of Malware removal, the computer’s manufacturer, model and processor architecture, etc. If MSS detects Malware or if an error occurs when MSS is running, a report is sent to Microsoft that contains basic information about the Malware or about the error. It works along with your existing antivirus software. It is meant to be used as an additional on-demand scanner in addition to your existing antivirus software, should you feel the need for a second opinion. The MSS is different from the Malicious Software Removal Tool – nor is it meant to be a replacement for using an antivirus software program that provides ongoing protection. Do note that it’s not exactly a small file … its msert.exe file is a 100 MB download! To rerun a scan with the latest anti-malware definitions, download and run the Microsoft Safety Scanner again. The Microsoft Safety Scanner expires 10 days after being downloaded.
