QuarantinePurgeItemsAfterDelay [in]

Indicates how many days items should kept in Quarantine folder before being removed.

RealTimeScanDirection [in]

Real-time scan direction - Enumeration

Both (0)

Incoming (1)

Outcoming (2)

RemediationScheduleDay [in]

Indicates what day of the week to perform the scheduled full scan to complete remediation.

Every Day (0)

Sunday (1)

Monday (2)

Tuesday (3)

Wednesday (4)

Thursday (5)

Friday (6)

Saturday (7)

Never (8)

RemediationScheduleTime [in]

Indicates what time to perform the scheduled full scan to complete remediation.

ReportingAdditionalActionTimeOut [in]

Configure timeout for detections requiring additional action.

ReportingCriticalFailureTimeOut [in]

Time in minutes for a detection in the 'critically failed' state to move to either 'additional action' or 'cleared' state.

ReportingNonCriticalTimeOut [in]

Time in minutes for a detection in the 'failed' state to move to the 'cleared' state.

ScanAvgCPULoadFactor [in]

Specify the maximum percentage of CPU utilization during a scan. This policy setting allows you to configure the maximum percentage CPU utilization permitted during a scan. Valid values for this setting are a percentage represented by the integers 5 to 100. A value of 0 indicates that there should be no throttling of CPU utilization.

CheckForSignaturesBeforeRunningScan [in]

When set, Windows Defender will check for new signatures before running a scan. If new signatures are found they will be downloaded and installed before the scan begins. If no new signatures are found, the scan will start based on the existing signatures.

ScanPurgeItemsAfterDelay [in]

Turn on removal of items from scan history folder. This setting defines the number of days items should be kept in the scan history folder before being permanently removed. The value represents the number of days to keep items in the folder. If set to zero, items will be kept forever and will not be automatically removed.

ScanOnlyIfIdleEnabled [in]

Run scheduled scans only if system is idle.

ScanParameters [in]

Specify the scan type to use for a scheduled scan.

Quick Scan (1)

Full Scan (2)

ScanScheduleDay [in]

Specify the day of the week to run a scheduled scan.

Every Day (0)

Sunday (1)

Monday (2)

Tuesday (3)

Wednesday (4)

Thursday (5)

Friday (6)

Saturday (7)

Never (8)

ScanScheduleQuickScanTime [in]

Specify the time of day to run a scheduled quick scan.

ScanScheduleTime [in]

Specify the time of day to run a scheduled scan.

SignatureFirstAuGracePeriod [in]

Aborts any service-initiated update immediately after first install by the configured amount of time.

SignatureAuGracePeriod [in]

Overrides CheckForSignatureBeforeRunningScan. Aborts any service-initiated update if signature was updated successfully within this amount of time. Time in minutes.

SignatureDefinitionUpdateFileSharesSources [in]

Defines the file shares for downloading definition updates. setting allows you to configure UNC file share sources for downloading definition updates. Sources will be contacted in the order specified. The value of this setting should be entered as a pipe-separated string enumerating the definition update sources. For example: {\\unc1 | \\unc2 }. The list is empty by default.

SignatureDisableUpdateOnStartupWithoutEngine [in]

When set to true, AM Service will not initiate definition update on start-up, regardless of whether an Engine is present or not.

SignatureFallbackOrder [in]

Define the order of sources for downloading definition updates This setting allows you to define the order in which different definition update sources should be contacted. The value of this setting should be entered as a pipe-separated string enumerating the definition update sources in order. Possible values are: 'InternalDefinitionUpdateServer' 'MicrosoftUpdateServer' 'MMPC' 'FileShares'

SignatureScheduleDay [in]

Indicates the day of the week in which signature updates occur. If set to zero then signature update occurs daily.

Every Day (0)

Sunday (1)

Monday (2)

Tuesday (3)

Wednesday (4)

Thursday (5)

Friday (6)

Saturday (7)

Never (8)

SignatureScheduleTime [in]

Specifies the time at which signature update check happens. By default the signatures are checked before the scheduled scan.

SignatureUpdateCatchupInterval [in]

Defines the number of days after which a catch-up signature is warranted. Works with SignatureUpdateLastChecked. 0 = no catch-up, 1 = 1 day, 2 = 2 days, etc.

SignatureUpdateInterval [in]

The time value is represented as the number of hours between update checks. Valid values range from 1 (every hour) to 24 (once per day).

MAPSReporting [in]

Join Microsoft MAPS.

Disabled (0)

Basic (1)

Advanced (2)

DisablePrivacyMode

Disable privacy mode.

RandomizeScheduleTaskTimes [in]

This setting allows you to enable or disable randomization of the scheduled scan start time and the scheduled definition update start time. This setting is used to distribute the resource impact of scanning. For example, it could be used in guest virtual machines sharing a host, to prevent multiple guest virtual machines from undertaking a disk-intensive operation at the same time.

DisableBehaviorMonitoring [in]

Disable behavior monitoring.

DisableIntrusionPreventionSystem [in]

Disable intrusion prevention system.

DisableIOAVProtection [in]

Disable IOAV protection.

DisableRealtimeMonitoring [in]

Disable real-time monitoring.

DisableScriptScanning [in]

Disable script scanning.

DisableArchiveScanning [in]

Disable archive scanning.

DisableCatchupFullScan [in]

Disable catch-up full scan. A catch-up scan is a scan that is initiated because a regularly scheduled scan was missed. Usually these scheduled scans are missed because the computer was turned off at the scheduled time.

DisableCatchupQuickScan [in]

Disable catch-up quick scan. A catch-up scan is a scan that is initiated because a regularly scheduled scan was missed. Usually these scheduled scans are missed because the computer was turned off at the scheduled time.
