Microsoft Defender Antivirus provides anomaly detection, a layer of protection for malware that doesn't fit any predefined pattern. Anomaly detection monitors for process creation events or files that are downloaded from the internet. Through machine learning and cloud-delivered protection, Microsoft Defender Antivirus can stay one step ahead of attackers. Anomaly detection is on by default and can help block attacks such as [3CX Security Alert for Electron Windows App](https://www.3cx.com/blog/news/desktopapp-security-alert/). Microsoft Defender Antivirus started blocking this malware four days before the attack was registered in VirusTotal.

We've also designed our antivirus solution to work in both online and offline scenarios. For offline scenarios, the latest dynamic intelligence from the Intelligence Security Graph is provisioned to the endpoint regularly throughout the day. When connected to the cloud, it's fed real-time intelligence from the [Intelligent Security Graph](https://www.microsoft.com/security/blog/2018/04/17/connect-to-the-intelligent-security-graph-using-a-new-api/).

Microsoft Defender Antivirus can also stop threats based on their behaviors and process trees even when the threat has started execution. A common example of these kinds of attacks is fileless malware. Microsoft's Next-generation protection features work together to identify and block malware based on abnormal behavior.
