Windows 11/10中的Windows Defender提供强大的反勒索软件保护。在这篇文章中，我们将向您展示如何启用勒索软件保护^{(Ransomware protection)}并保护您的系统以及数据文件夹。

勒索软件^(Ransomware)是一种恶意软件，它会锁定您的文件、数据或 PC 本身，并向您勒索金钱以提供访问权限。这是恶意软件编写者为他们在网络上的非法活动“筹集资金”的一种新方式。

^{(Ransomware Protection)}Windows Defender中的勒索软件保护

要在Windows 安全中心或 Microsoft Defender中启用勒索软件保护：

1. 打开 Windows 后卫
2. 选择病毒和威胁防护
3. 单击^(Click)管理^(Manage)勒索软件保护
4. 打开受控文件夹访问
5. 添加要保护的文件夹。

让我们详细看看过程。

通过右键单击其系统托盘图标启动Windows 安全性^{(Windows Security)}

单击查看安全仪表板

从左侧，选择病毒^(Virus)和威胁防护。

在勒索软件保护^{(Ransomware protection)}下，单击管理勒索软件保护^{(Manage ransomware protection)}。

打开受控文件夹访问。此功能可保护系统上的文件、文件夹和内存区域免受恶意软件未经授权的更改。

然后你会发现另外两个选项——受保护的文件夹^{(Protected folders )}和允许应用程序通过受控文件夹访问^{(Allow an app through Controlled folder access)}。单击^(Click)“受保护的文件夹”以管理当前受保护的文件夹。您可能无法从列表中删除任何文件夹，但您当然可以通过单击“添加受保护的文件夹^{(Add a protected folder )}”按钮添加更多文件夹。

如果您在文件夹上启用了受控文件夹访问^{(Controlled folder access)}，并且如果任何未经授权的应用程序或进程尝试访问它并更改其内容，则该尝试将被停止，并且您将在屏幕右下角看到未经授权的更改被阻止通知。^{(Unauthorized changes blocked)}

创建勒索软件的唯一原因是恶意软件编写者将其视为一种简单的赚钱方式。诸如未打补丁的软件、过时的操作系统或人们的无知之类的漏洞对这些有恶意和犯罪意图的人是有益的。因此^(Hence)，采取预防措施保护自己免受勒索软件攻击^{(protect yourself against Ransomware attacks)}是最好的方法。

Enable and configure Ransomware Protection in Windows Defender

Windows Defendеr in Windows 11/10 offers robust anti-ransomware protectiоn. In this post, we will ѕhow you how tо enable Ransomware protection and protect your system as well as data folders.

Ransomware is a type of malware that locks your files, data or the PC itself and extorts money from you in order to provide access. This is a new way for malware writers to ‘collect funds’ for their illegitimate activities on the web.

Ransomware Protection in Windows Defender

To enable Ransomware protection in Windows Security or Microsoft Defender:

1. Open Windows Defender
2. Select Virus and threat protection
3. Click on Manage ransomware protection
4. Turn ON Controlled folder access
5. Add the folders you want to protect.

Let us see the procedure in detail.

Launch Windows Security by right-clicking on its system tray icon

Click on View security dashboard

From the left side, select Virus and threat protection.

Under Ransomware protection, click on Manage ransomware protection.

Turn ON Controlled folder access. This feature protects files, folders, and memory areas on your system from unauthorized changes by malware.

Then you will find two more options – Protected folders and Allow an app through Controlled folder access. Click on “Protected folders” to manage the folders that are being protected right now. You may not be able to remove any folder from the list, but you can certainly add more folders by clicking on the Add a protected folder button.

If you have enabled Controlled folder access and on a folder and if any unauthorized app or process tries to access it and change its contents, the attempt will be stopped, and you will see Unauthorized changes blocked notification in the bottom right corner of your screen.

The only reason ransomware is created, is because the malware writers see it as an easy way to make money. Vulnerabilities such as unpatched software, outdated operating systems, or people’s ignorance is beneficial for such people with malicious and criminal intentions. Hence, taking preventive steps to protect yourself against Ransomware attacks is the best way.

It not only endangers your data, but it can also breach your privacy to such an extent that it can harm your reputation also.
