1. In the event Microsoft Defender Antivirus can't make a clear determination, file metadata is sent to the cloud protection service. Often within milliseconds, the cloud protection service can determine based on the metadata as to whether the file is malicious or not a threat.

- Can be synchronous or asynchronous. For synchronous, the file won't open until the cloud renders a verdict. For asynchronous, the file opens while cloud protection performs its analysis.

- Metadata can include PE attributes, static file attributes, dynamic and contextual attributes, and more (see [Examples of metadata sent to the cloud protection service](#examples-of-metadata-sent-to-the-cloud-protection-service)).

1. After examining the metadata, if Microsoft Defender Antivirus cloud protection can't reach a conclusive verdict, it can request a sample of the file for further inspection. This request honors the settings configuration for sample submission:

1.**Send safe samples automatically**

- Safe samples are samples considered to not commonly contain PII data like: .bat, .scr, .dll, .exe.

- If file is likely to contain PII, the user gets a request to allow file sample submission.
71

- This option is the default on Windows, macOS, and Linux.

1. After files are submitted to cloud protection, the submitted files can be **scanned**, **detonated**, and processed through **big data analysis****machine-learning** models to reach a verdict. Turning off cloud-delivered protection limits analysis to only what the client can provide through local machine-learning models, and similar functions.

> [Block at first sight (BAFS)](configure-block-at-first-sight-microsoft-defender-antivirus.md) provides detonation and analysis to determine whether a file or process is safe. BAFS can delay the opening of a file momentarily until a verdict is reached. If you disable sample submission, BAFS is also disabled, and file analysis is limited to metadata only. We recommend keeping sample submission and BAFS enabled.
