Windows Defender可以扫描和监控^{(Windows Defender)}Windows 11/10中几乎所有的文件夹。如果您的文件夹可能包含可以向Windows 安全^{(Windows Security)}中心发送警报的文件，那么最好将排除项添加^{(Add an exclusion)}到Windows 安全中心^{(Windows Security)}。如果您确定文件夹的内容是安全的并且Windows Defender只会抛出误报警告，则可以这样做。这样，以后就不会扫描这些文件夹了。同样，^(Again)您可能会从防病毒扫描中排除^{(Windows files and folders you may exclude from Antivirus scans)}一些Windows 文件和文件夹- 您可能希望这样做以节省扫描时间。

按照分步指南从Windows 安全^{(Windows Security)}扫描中排除文件、文件夹、进程或文件类型。

从Windows Defender 安全^{(Windows Defender Security)}扫描中排除文件夹

当您信任文件类型或文件夹或您相信的任何进程，但Windows 安全^{(Windows Security)}中心认为它是恶意的时，此功能也会派上用场。

虽然它不会发生在每个人身上，但这对于那些沉迷于开发的人来说非常方便。

^(Search)在搜索框中^(Search)搜索Windows 安全^{(Windows Security)}并单击它以启动它。

单击^(Click)病毒^(Virus)和威胁防护> Manage设置> Add或删除排除项。

在下一个屏幕中，单击添加^(Add)排除 >文件夹^(Folder)。该列表将包括文件^(File)、文件夹^(Folder)、文件类型^{(File Type)}和进程^(Process)。

在下一个窗口中，单击“+添加和排除”，选择一个文件夹，然后单击“确定”将其包含在“排除^(Exclusions)”列表中。

要删除它，请单击“向下”箭头按钮，然后单击“删除^(Remove)”按钮。

请注意，如果您只想忽略一些文件类型，最好将防病毒软件配置为忽略具有特定扩展名的文件。这样，无论它们的位置如何，它都会忽略所有这些。

当您选择一个文件夹时，所有子文件夹也将被排除。所以一定要明白你在做什么。

阅读^(Read)：如何将文件类型或进程排除添加到 Windows 安全性^{(add a File type or Process Exclusion to Windows Security)}。

一旦你这样做了，我还建议使用受控文件夹访问来保护文件夹。由于文件没有受到威胁监控，受控文件夹访问将确保外部程序不会修改它。这样，您的文件夹将永远是安全的。

提示^(TIP)：您还可以 在上下文菜单中包括添加排除项。^{(Add an exclusion)(Add an exclusion)}

How to exclude a folder from Windows Defender scan in Windows 11/10

Windows Defender can scan and monitor almost all the folders in Windows 11/10. In case you have a folder that may have files that could send an alarm to Windows Security, then it is best to Add an exclusion to Windows Security. It is fine to do that if you are sure that the contents of the folder are safe and Windows Defender is only throwing out false-positive warnings. That way, it will not scan those folders in the future. Again, there are some Windows files and folders you may exclude from Antivirus scans – and you may want to do that to save your scan time.

Follow the step by step guide to exclude a file, folder, process or file type from Windows Security scan.

Exclude a folder from Windows Defender Security scan

This feature also comes in handy when you trust a file type or folder or any process that you believe, but Windows Security thinks it is malicious.

While it does not happen to everyone, but this is very handy for those who indulge themselves in development.

Search for Windows Security in the Search box and click on it to launch it.

Click on Virus & threat protection > Manage settings > Add or remove exclusions.

In the next screen, click on Add an exclusion > Folder. The list will include File, Folder, File Type, and Process.

In the next window, click on “+Add and exclusion”, select a folder, and click OK to include it in the Exclusions list.

To remove it, click on the ‘down’ arrow button, and then click on the Remove button.

Do note that if you are only want to ignore a few file types, it is best to configure the antivirus to ignore files with a specific extension. That way it will ignore all of them no matter their location.

When you select a folder, all the subfolders will be excluded as well. So be sure to understand what you are doing.

Read: How to add a File type or Process Exclusion to Windows Security.

Once you do that, I will also suggest protecting the folder using Controlled Folder Access. Since the file is not monitored for threat,  the controlled folder access will make sure an external program does not modify it.  That way, your folder will always be secure.

TIP: You can also include Add an exclusion in the context menu.
