When antivirus finds a suspicious file, it can prevent the file from running while it queries the [antivirus cloud service](utilize-microsoft-cloud-protection-windows-defender-antivirus.md).
When Windows Defender Antivirus is suspicious of a file, it can prevent the file from running while it queries the [Windows Defender Antivirus cloud-protection service](utilize-microsoft-cloud-protection-windows-defender-antivirus.md).
The default period that the file will be [blocked](configure-block-at-first-sight-windows-defender-antivirus.md) for is 10 seconds. You can specify an additional period of time to wait before the file is allowed to run. This can help ensure there is enough time to receive a proper determination from the Windows Defender Antivirus cloud.
