The Microsoft Malicious Software Removal Tool (MSRT) is updated monthly with new malware detections – so far this year we have added 29 malware families. This month we are updating our detections for some of the malware families already included in the tool.
We choose the malware families we add to the MSRT each month using several criteria. One of the most common reasons is the prevalence of a family in the malware ecosystem. For example, in recent months we focused on file-encrypting ransomware threats. This is due to prevalence and the impact that ransomware can have in enterprise and home user environments. Since January, we added the following ransomware families to the MSRT:
The MSRT has remediated these threats on almost 24,000 machines.
Reviewing our data throughout the year helps us determine the impact of our detection and remediation efforts. Analyzing our telemetry helps us to provide coverage for the most prevalent threats encountered by our customers.
The MSRT works in tandem with real-time antimalware products such as Windows Defender for Windows 10. An up-to-date real-time security product is the best protection against malware and unwanted software. It's also important to keep all your software up-to date and regularly back up your files.
