Графический интерфейс Windows Defender

В версиях Windows Server 2016 и 2019 (в том числе в Core редакции) уже встроен движок антивируса Windows Defender (Защитник Windows). Вы можете проверить наличие установленного компонента Windows Defender Antivirus с помощью PowerShell:

Get-WindowsFeature | Where-Object {$_. name -like "*defender*"} | ft Name,DisplayName,Installstate

проверить, что движок Microsoft Defender антивируса установлен в Windows Server

Однако в Windows Server 2016 у Windows Defender по-умолчанию нет графического интерфейса управления. Вы можете установить графическую оболочку Windows Defender в Windows Server 2016 через консоль Server Manager (Add Roles and Features -> Features -> Windows Defender Features -> компонент GUI for Windows Defender).

GUI for Windows Defender установка на Windows Server 2016

Установить графический компонент антивируса Windows Defender можно с помощью PowerShell командлета Install-WindowsFeature:

Install-WindowsFeature -Name Windows-Defender-GUI

Для удаления графического консоли Defender используется командлет:
Uninstall-WindowsFeature -Name Windows-Defender-GUI

В Windows Server 2019 графический интерфейс Defender основан на APPX приложении и доступен через меню Windows Security (панель Settings -> Update and Security).

Настройка Windows Defender производится через меню “Virus and threat protection”.

Панель управления Virus and threat protection в Windows Server 2019

Если вы не можете открыть меню настроек Defender, а при запуске апплета Windows Security у вас появляется ошибка “You’ll need a new app to open this windowsdefender”, нужно перерегистрировать APPX приложение с помощью файла манифеста такой командой PowerShell:

Add-AppxPackage -Register -DisableDevelopmentMode "C:\Windows\SystemApps\Microsoft.Windows.SecHealthUI_cw5n1h2txyewy\AppXManifest.xml"

Если APPX приложение полностью удалено, можно его восстановить вручную по аналогии с восстановлением приложения Micorosft Store.

Удаление антивируса Microsoft Defender в Windows Server 2019 и 2016

В Windows 10 при установке любого стороннего антивируса (Kaspersky, McAfee, Symantec, и т.д.) встроенный антивирус Windows Defender автоматически отключается, однако в Windows Server этого не происходит. Отключать компонент встроенного антивируса нужно вручную (в большинстве случаев не рекомендуется использовать одновременно несколько разных антивирусов на одном компьютере/сервере).

Удалить компонент Windows Defender в Windows Server 2019/2016 можно из графической консоли Server Manager или такой PowerShell командой:

Uninstall-WindowsFeature -Name Windows-Defender

Не удаляйте Windows Defender, если на сервере отсутствует другой антивирус.

Установить службы Windows Defender можно командой:

Add-WindowsFeature Windows-Defender-Features,Windows-Defender-GUI

Управление Windows Defender с помощью PowerShell

Рассмотрим типовые команды PowerShell, которые можно использовать для управления антивирусом Windows Defender.

Проверить, запущена ли служба Windows Defender Antivirus Service можно с помощью команды PowerShell Get-Service:

Get-Service WinDefend

служба WinDefend (Windows Defender Antivirus Service )

Как вы видите, служба запушена (статус –
Running
).

Текущие настройки и статус Defender можно вывести с помощью командлета:

Get-MpComputerStatus

Вывод комадлета содержит версию и дату обновления антивирусных баз (AntivirusSignatureLastUpdated, AntispywareSignatureLastUpdated), включенные компоненты антвируса, время последнего сканирования (QuickScanStartTime) и т.д.

Отключить защиту в реальном времени Windows Defender (RealTimeProtectionEnabled) можно с помощью команды:

Set-MpPreference -DisableRealtimeMonitoring $true

После выполнения данной команды, антивирус не будет сканировать на лету все обрабатываемые системой файлы.

Включить защиту в реальном времени:

Set-MpPreference -DisableRealtimeMonitoring $false

Более полный список командлетов PowerShell, которые можно использовать для управления антивирусом есть в статье Управление Windows Defender с помощью PowerShell.

Добавить исключения в антивирусе Windows Defender

В антивирусе Microsoft можно задать список исключений – это имена, расширения файлов, каталоги, которые нужно исключить из автоматической проверки антивирусом Windows Defender.

Особенность Защитника в Windows Server – он автоматически генерируемый список исключений антивируса, который применяется в зависимости от установленных ролей сервера. Например, при установке роли Hyper-V в исключения антивируса добавляются файлы виртуальных и дифференциальных дисков, vhds дисков (*.vhd, *.vhdx, *.avhd), снапшоты и другие файлы виртуальных машин, каталоги и процессы Hyper-V (Vmms.exe, Vmwp.exe)

Если нужно отключить автоматические исключения Microsoft Defender, выполните команду:

Set-MpPreference -DisableAutoExclusions $true

Чтобы вручную добавить определенные каталоги в список исключения антивируса, выполните команду:

Set-MpPreference -ExclusionPath "C:\Test", "C:\VM", "C:\Nano"

Чтобы исключить антивирусную проверку определенных процессов, выполните команду:

Set-MpPreference -ExclusionProcess "vmms.exe", "Vmwp.exe"

Получаем статус Windows Defender с удаленных компьютеров через PowerShell

Вы можете удаленно опросить состояние Microsoft Defender на удаленных компьютерах с помощью PowerShell. Следующий простой скрипт при помощи командлета Get-ADComputer выберет все Windows Server хосты в домене и через WinRM (командлетом Invoke-Command) получит состояние антивируса, время последнего обновления баз и т.д.

$Report = @() $servers= Get-ADComputer -Filter 'operatingsystem -like "*server*" -and enabled -eq "true"'| Select-Object -ExpandProperty Name foreach ($server in $servers) { $defenderinfo= Invoke-Command $server -ScriptBlock {Get-MpComputerStatus | Select-Object -Property Antivirusenabled,RealTimeProtectionEnabled,AntivirusSignatureLastUpdated,QuickScanAge,FullScanAge} If ($defenderinfo) { $objReport = [PSCustomObject]@{ User = $defenderinfo.PSComputername Antivirusenabled = $defenderinfo.Antivirusenabled RealTimeProtectionEnabled = $defenderinfo.RealTimeProtectionEnabled AntivirusSignatureLastUpdated = $defenderinfo.AntivirusSignatureLastUpdated QuickScanAge = $defenderinfo.QuickScanAge FullScanAge = $defenderinfo.FullScanAge } $Report += $objReport } } $Report|ft

Опрос состояния Microsoft Defender на серверах Windows Server в домене Active Directory через PowerShell

Для получения информации о срабатываниях антивируса с удаленных компьютеров можно использовать такой PowerShell скрипт:

$Report = @() $servers= Get-ADComputer -Filter 'operatingsystem -like "*server*" -and enabled -eq "true"'| Select-Object -ExpandProperty Name foreach ($server in $servers) { $defenderalerts= Invoke-Command $server -ScriptBlock {Get-MpThreatDetection | Select-Object -Property DomainUser,ProcessName,InitialDetectionTime ,CleaningActionID,Resources } If ($defenderalerts) { foreach ($defenderalert in $defenderalerts) { $objReport = [PSCustomObject]@{ Computer = $defenderalert.PSComputername DomainUser = $defenderalert.DomainUser ProcessName = $defenderalert.ProcessName InitialDetectionTime = $defenderalert.InitialDetectionTime CleaningActionID = $defenderalert.CleaningActionID Resources = $defenderalert.Resources } $Report += $objReport } } } $Report|ft

В отчете видно имя зараженного файла, выполненное действие, пользователь и процесс-владелец.

Обновление антивируса Windows Defender

Антивирус Windows Defender может автоматически обновляться из Интернета с серверов Windows Update. Если в вашей внутренней сети установлен сервер WSUS, антивирус может получать обновления с него. Убедитесь, что установка обновлений одобрена на стороне WSUS сервера (в консоли WSUS обновления антивирусных баз Windows Defender, называются Definition Updates), а клиенты нацелены на нужный сервер WSUS с помощью GPO.

В некоторых случаях, после получения кривого обновления, Защитник Windows может работать некорректно. В этом случае рекомендуется сбросить текущие базы и перекачать их заново:

"%PROGRAMFILES%\Windows Defender\MPCMDRUN.exe" -RemoveDefinitions -All "%PROGRAMFILES%\Windows Defender\MPCMDRUN.exe" –SignatureUpdate

Если на сервере нет прямого доступа в Интернет, вы можете настроить обновление Microsoft Defender из сетевой папки.

Скачайте обновления Windows Defender вручную (https://www.microsoft.com/en-us/wdsi/defenderupdates) и помесите в сетевую папку.

Укажите путь к сетевому каталогу с обновлениями в настройках Defender:
Set-MpPreference -SignatureDefinitionUpdateFileSharesSources \\fs01\Updates\Defender

Запустите обновление базы сигнатур:

Update-MpSignature -UpdateSource FileShares

Управление настройками Microsoft Defender Antivirus с помощью GPO

Вы можете управлять основными параметрами Microsoft Defender на компьютерах и серверах домена централизованно с помощью GPO. Для этого используется отдельный раздел групповых политик Computer Configurations -> Administrative Template -> Windows Component -> Windows Defender Antivirus.

В этом разделе доступно более 100 различных параметров для управления настройками Microsoft Defender.

Например, для отключения антивируса Microsoft Defender нужно включить параметр GPO Turn off Windows Defender Antivirus.
