Select cloud protection level

Information

This policy setting determines how aggressive Microsoft Defender Antivirus will be in blocking and scanning suspicious files. If this setting is on Microsoft Defender Antivirus will be more aggressive when identifying suspicious files to block and scan; otherwise it will be less aggressive and therefore block and scan with less frequency. For more information about specific values that are supported see the Microsoft Defender Antivirus documentation site. Note: This feature requires the 'Join Microsoft MAPS' setting enabled in order to function. Possible options are: (0x0) Default Microsoft Defender Antivirus blocking level (0x1) Moderate Microsoft Defender Antivirus blocking level delivers verdict only for high confidence detections (0x2) High blocking level - aggressively block unknowns while optimizing client performance (greater chance of false positives) (0x4) High+ blocking level -- aggressively block unknowns and apply additional protection measures (may impact client performance) (0x6) Zero tolerance blocking level -- block all unknown executables
