默认情况下， Windows 10 中的Windows Defender不会扫描映射的网络驱动器。在这篇文章中，我们将向您展示如何配置 Windows Defender以使其在完整扫描期间扫描映射的网络驱动器，从而获得更好和改进的安全性和保护。在快速扫描和自定义扫描期间始终可以扫描映射的网络驱动器。^(Mapped)

您可以使用以下三种方式之一将 Windows Defender 配置为在运行完整扫描时扫描映射网络驱动器内容中的恶意软件和 PUP ；^{(configure Windows Defender to scan for malware and PUPs)}

1. 组策略编辑器。
2. 注册表编辑器。
3. 电源外壳。

让我们详细看一下过程。

^{(Scan Mapped Network)}使用Windows Defender^{(Windows Defender)}扫描映射的网络驱动器

1]通过组策略编辑器^{(1] Via Group Policy Editor)}

按Windows键 + R。在“运行”^(Run)对话框中，键入gpedit.msc，按 Enter^(Enter)启动组策略编辑器^{(Group Policy Editor)}。

在Local Group Policy Editor的左窗格中，导航到以下位置：

Computer Configuration > Administrative Templates > Windows Components > Windows Defender Antivirus > Scan

此策略设置允许您配置扫描映射的网络驱动器。

• 如果启用此设置，将扫描映射的网络驱动器。
• 如果您禁用或不配置此设置，则不会扫描映射的网络驱动器。

在本地组策略编辑器窗口中^{(Local Group Policy Editor)}扫描^(Scan)的右窗格中，双击对映射的网络驱动器策略运行完全扫描^{(Run full scan on mapped network drives)}以编辑其属性。

要在完整扫描期间包括映射的网络驱动器^{(Mapped Network Drives)}，请选择已启用^(Enabled)的单选按钮。否则，选择未配置^{(Not Configured)}或禁用^(Disabled)的单选按钮，然后单击应用^(Apply)>确定^(OK)，以在完整扫描期间排除映射的网络驱动器。^{(Mapped Network Drives)}

未配置^{(Not Configured)}是默认设置。

完成后，您可以退出本地组策略编辑器^{(Local Group Policy Editor)}窗口。

2]通过注册表编辑器^{(2] Via Registry Editor)}

按Windows键 + R。在“运行”^(Run)对话框中，键入regedit ，按 Enter，在UAC提示符上单击“是”以启动^(Yes)注册表编辑器^{(Registry Editor)}。

导航到以下注册表^(Registry)项：

HKEY_LOCAL_MACHINE > SOFTWARE > Policies > Microsoft > Windows Defender > Scan

如果您没有Scan密钥，请通过右键单击Windows Defender创建它，然后单击New > Key。

现在，您可以创建一个名为DisableScanningMappedNetworkDrivesForFullScan的新^{(DisableScanningMappedNetworkDrivesForFullScan.)}DWORD（32 位）值。^(Value)

现在双击这个新创建的值来编辑它的属性。

• 要启用它，请将其值设为0
• 要禁用它，请将其值设为1

重新启动您的电脑。

3]使用PowerShell^{(3] Using PowerShell)}

打开 Windows PowerShell（管理员）^{(Open Windows PowerShell (Admin))}。在PowerShell环境中，键入或复制粘贴以下命令之一，然后按 Enter：

要启用网络驱动器扫描：

Set-MpPreference -DisableScanningMappedNetworkDrivesForFullScan 0

要禁用网络驱动器扫描：

Set-MpPreference -DisableScanningMappedNetworkDrivesForFullScan 1

此处不需要重新启动。该设置会立即应用。

因此，您可以让 Windows Defender 扫描映射的网络驱动器。
^{(Thus, you can make Windows Defender scan mapped network drives.)}

How to scan Mapped Network Drives with Windows Defender

By defaυlt, Windows Defender in Windows 10 does not scan mapped network drives. In this post, we will show you how to configure Windows Defender to make it scan mapped network drives during a full scan, for better and improved security and protection. Mapped network drives can always be scanned during a quick scan and custom scan.

You can configure Windows Defender to scan for malware and PUPs in the contents of mapped network drives when running a full scan, by using any of the three following ways;

1. Group Policy Editor.
2. Registry Editor.
3. PowerShell.

Let’s take a look at the procedure in detail.

Scan Mapped Network Drives with Windows Defender

1] Via Group Policy Editor

Press Windows key + R. In the Run dialog, type gpedit.msc, hit Enter to launch Group Policy Editor.

In the left pane of Local Group Policy Editor, navigate to the following location:

Computer Configuration > Administrative Templates > Windows Components > Windows Defender Antivirus > Scan

This policy setting allows you to configure scanning mapped network drives.

• If you enable this setting, mapped network drives will be scanned.
• If you disable or do not configure this setting, mapped network drives will not be scanned.

In the right pane of Scan in the Local Group Policy Editor window, double-click Run full scan on mapped network drives policy to edit its properties.

To include Mapped Network Drives during a full scan, select the radio button for Enabled. Otherwise, select the radio button for Not Configured or Disabled and click Apply > OK, to exclude Mapped Network Drives during a full scan.

Not Configured is the default setting.

You can exit the Local Group Policy Editor window when done.

2] Via Registry Editor

Press Windows key + R. In the Run dialog box, type regedit, hit Enter, click Yes on UAC prompt to launch Registry Editor.

Navigate to the following Registry key:

HKEY_LOCAL_MACHINE > SOFTWARE > Policies > Microsoft > Windows Defender > Scan

If you don’t have the Scan key, create it by right-clicking Windows Defender, then click New > Key.

Now, you can create a new DWORD (32-bit) Value named DisableScanningMappedNetworkDrivesForFullScan.

Now double-click this newly created value to edit its properties.

• To enable it, give it a value of 0
• To disable it, give it a value of 1

Restart your PC.

3] Using PowerShell

Open Windows PowerShell (Admin). In the PowerShell environment, type or copy-paste one of the following commands and hit Enter:

To enable scanning of network drives:

Set-MpPreference -DisableScanningMappedNetworkDrivesForFullScan 0

To disable scanning of network drives:

Set-MpPreference -DisableScanningMappedNetworkDrivesForFullScan 1

A restart is not required here. The setting is applied instantly.

Thus, you can make Windows Defender scan mapped network drives.
