The Windows Defender Antivirus from Windows 10 has a couple of excellent protection features, some of which are misunderstood. Two of them are named Cloud-delivered protection and Automatic sample submission, and they work in tandem. With their help, you get efficient protection against unknown threats that have not yet been discovered on other computers. If you are considering disabling them, or you want to know what they do to decide whether to keep them enabled, read this article: NOTE: The features shared in this article were first introduced in Windows 10 with Anniversary Update. However, some things have changed with the latest updates, and we updated the article accordingly. What is Cloud-delivered protection in Windows 10? According to Microsoft, \"approximately 96% of all malware files detected and blocked by Windows Defender Antivirus are observed only once on a single computer, demonstrating the polymorphic and targeted nature of modern attacks, and the fragmented state of the threat landscape. Hence, blocking malware at first sight is a critical protection capability.\" The cloud-delivered protection feature from Windows 10 enables Windows Defender Antivirus to block most new, never-before-seen threats at first sight. When Windows Defender Antivirus needs additional intelligence to verify the intent of a suspicious file, it sends some metadata to the cloud protection service created by Microsoft, which can determine whether the file is safe or malicious within milliseconds. Cloud-delivered protection and Automatic sample submission When the Windows Defender Antivirus cloud-delivered protection service is unable to reach a conclusive verdict, it can request the potential malware sample for further inspection. If Automatic sample submission is enabled, Windows Defender Antivirus uploads the suspicious files that it finds to the cloud protection service, for rapid analysis. While waiting for a verdict, Windows Defender Antivirus maintains a lock on those files, preventing possible malicious behavior. The Windows Defender Antivirus then takes action based on the decision received from the cloud-delivered protection service. For example, if the cloud protection service determines a file as malicious, it blocks the file from running, providing instant protection. By default, Windows Defender Antivirus is set to wait for up to 10 seconds to hear back from the cloud protection service before letting suspicious files run.
