The first results were very positive with this tool and we are actively reviewing the telemetry of our customers who use it to better understand aspects of the impact of threats from specific malware families. In addition, we invite our customers to install security updates provided by Microsoft operating systems and applications, as well as other third-party applications and all the security updates that can be provided by Internet service providers. Telemetry collected by the first release of Microsoft security scanner echoes this constant messaging.
