Windows Defender是微软(Microsoft)自家的杀毒产品(in-house antivirus product)，长期以来一直在保护用户。但是，在微软(Microsoft)的Windows 8.1和Windows 10中，它的界面和可用性(interface and usability)并没有太大的提升。幸运的是，好时光也来了，在Windows 10创意者更新(Update)中，我们获得了一个名为Windows Defender 安全中心(Windows Defender Security Center)的新应用程序，它承诺让我们比以往任何时候都更容易查看和控制Windows保护我们免受恶意软件侵害的方式与其他安全威胁一样。在今天的文章中，我们将向您展示它提供的功能以及如何使用Windows Defender 安全中心(Windows Defender Security Center)：
如何打开Windows Defender 安全中心(Windows Defender Security Center)
Windows Defender 安全中心(Windows Defender Security Center)是一个通用的Windows平台(Windows platform)应用程序，它预装在Windows 10 创意者更新(Creators Update)中。您可以在“开始”菜单的“(Start Menu)所有应用(All apps)”列表中找到它。
打开Windows Defender 安全中心(Windows Defender Security Center)的另一种方法是搜索它。在任务栏中的Cortana搜索字段(search field)中，输入单词defer(defender)，然后单击或点击相应的搜索结果(search result)。
打开Windows Defender 安全中心(Windows Defender Security Center)的第三种也是最麻烦的方法是从“设置”应用程序(Settings app)中进行。您将在Windows Defender(Windows Defender)部分的更新和安全(Update & security)设置类别中找到它的启动按钮。
打开后，Windows Defender 安全中心(Windows Defender Security Center)如下所示：
您将在Windows Defender 安全中心内找到的安全工具和控件(Windows Defender Security Center)
Windows Defender 安全中心(Windows Defender Security Center) 主页分为(home page)几个主要部分。窗口的上半部分显示设备运行状况的简要摘要，主页的下半部分可让您访问Windows 10中的基本保护工具和控件。它们分为五个主要类别：
- 病毒和威胁防护(Virus & threat protection)
- 设备性能和健康(Device performance & health)
- 防火墙和网络保护(Firewall & network protection)
- 应用程序和浏览器控制(App & browser control)
- 家庭选择(Family options)
您可以访问这些部分中的每一个，以及左侧菜单中的一些其他设置，可以通过单击/点击应用程序窗口左上角(left corner)的(left menu)汉堡包图标(app window)来展开这些(hamburger icon)设置。
让我们看看每个安全部分必须提供什么：
1.检查您的防病毒保护(antivirus protection)并运行扫描
病毒和威胁防护(Virus & threat protection)部分显示的内容取决于您是使用Windows Defender作为主要防病毒软件，还是安装了第三方防病毒解决方案(antivirus solution)。
如果您安装了第三方防病毒软件，则可以从此处启动它，仅此而已。但是，如果您依靠Windows Defender来保护您免受恶意软件的侵害，则此部分将让您“查看威胁历史记录、扫描病毒和其他威胁、指定保护设置并获取保护更新”("View threat history, scan for viruses and other threats, specify protection settings, and get protection updates")。
扫描历史记录(Scan history)区域显示是否在您的 Windows 10 设备上发现威胁、发现的威胁数量以及 Windows Defender 已扫描的文件数量(Windows Defender)。如果您想运行手动防病毒扫描，您可以从这里开始快速扫描(Quick scan)或运行高级扫描(Advanced scan)。
如果要运行高级扫描(Advanced scan)，请单击或点击(click or tap)同名链接，然后选择要运行的高级扫描类型：完整扫描、自定义扫描或脱机扫描。全面扫描“检查硬盘上的所有文件和正在运行的程序”(Full scan "checks all files and running programs on your hard disk")，可能需要一个多小时。自定义扫描(Custom scan)可让您“选择要检查的文件和位置”。("choose which files and locations you want to check".)Windows Defender 离线扫描(Windows Defender Offline scan)将重新启动您的Windows 10设备，并在操作系统(operating system)启动之前尝试查找并删除恶意软件。
返回病毒和威胁防护(Virus & threat protection)部分，您还可以访问控制Windows Defender在您的 PC 上工作方式的设置。要访问它们，请单击/点击“病毒和威胁防护设置”(Virus & threat protection settings)链接。
在病毒和威胁防护设置中(Virus & threat protection settings)，您将获得一些开关和一些链接，用于按照您想要的方式进行设置。您可以打开或关闭以下功能：
-
实时保护(Real-time protection)—— “定位并阻止恶意软件在您的设备上安装或运行”("locates and stops malware from installing or running on your device")。我们强烈建议您保留此功能，因为它是您抵御病毒的第一道屏障。但是，即使您确实选择禁用它，它也会在短时间内自动重新打开。
-
基于云的保护(Cloud-based protection)- 让您可以从云端访问Microsoft服务器上可用的最新病毒定义。建议您启用此选项。
-
自动提交样本(Automatic sample submission)- 让Microsoft(Microsoft fetch)从您的 Windows 10 设备获取样本文件并分析它们是否存在威胁。如果文件包含个人信息，Microsoft承诺会询问您。否则，样品将被提交而没有任何其他问题。建议您也将此功能保持打开状态，因为它可以帮助Windows Defender在发现新的恶意软件威胁时更快地做出反应。
-
排除项(Exclusions)- 允许您选择不想被Windows Defender扫描的文件、文件夹、文件类型和进程。
-
通知(Notifications)- 允许或禁止Windows Defender向您发送有关最新防病毒扫描和/或有关被Windows 防火墙(Windows Firewall)阻止的应用程序的通知。
最后，按应用程序左上角的后退(left corner)箭头图标(arrow icon)，最后一次返回病毒和威胁防护。(Virus & threat protection)您将在此页面底部看到的最后一件事是称为保护更新( Protection updates)的区域。在这里您可以“查看有关您的威胁定义版本的信息，并检查更新”("view information about your threat definition version, and check for updates")。
这就是Windows Defender 安全中心应用程序中有关(Windows Defender Security Center)病毒和威胁防护(Virus & threat protection)部分的所有信息。让我们继续第二部分：设备性能和健康(Device performance & health)。点击(Click)本教程第二页继续阅读。
5 things you can do with the new Windows Defender Security Center
Windows Defender is Microsoft's in-house antivirus product, and it has been protecting users for a long time now. However, in Microsoft's Windows 8.1 and Windows 10, its interface and usability didn't improve much. Luckily, good times have come to it too, and in Windows 10 Creators Update we get a new app called Windows Defender Security Center, which promises to make it easier than ever for us to view and control the way Windows protects us from malware as well as from other security threats. In today's article, we'll show you what it has to offer and how to use Windows Defender Security Center:
How to open Windows Defender Security Center
The Windows Defender Security Center is a universal Windows platform app, and it's pre-installed in Windows 10 Creators Update. You can find it inside the All apps list from your Start Menu.
An alternative way to open Windows Defender Security Center is to search for it. In Cortana's search field from your taskbar, enter the word defender and then click or tap on the appropriate search result.
The third and the most cumbersome method to open Windows Defender Security Center is to do it from the Settings app. You'll find a launch button for it in the Windows Defender section from the Update & security category of settings.
Once you've opened it, this is what the Windows Defender Security Center looks like:
The security tools and controls you'll find inside Windows Defender Security Center
The Windows Defender Security Center home page is split into a few main sections. The top half of the window shows you a brief summary of your device's health, and the bottom half of the homepage gives you access to the essential protection tools and controls found in Windows 10. They are split into five main categories:
- Virus & threat protection
- Device performance & health
- Firewall & network protection
- App & browser control
- Family options
You can access each of these sections, plus a few additional settings from the left menu, which can be expanded with a click/tap on the hamburger icon found in the top left corner of the app window.
Let's see what each of these security sections has to offer:
1. Check your antivirus protection and run scans
What the Virus & threat protection section shows you depends on whether you use Windows Defender as your main antivirus, or you have installed a third-party antivirus solution.
If you installed a third-party antivirus, you can launch it from here, and that's all. If however, you rely on Windows Defender to protect you against malware, this section will let you "View threat history, scan for viruses and other threats, specify protection settings, and get protection updates".
The Scan history area shows you whether threats have been found on your Windows 10 device, how many of them were found, and the number of files Windows Defender has scanned. If you want to run a manual antivirus scan, this is the place from which you can start a Quick scan, or run an Advanced scan.
If you want to run an Advanced scan, click or tap on the link with the same name, and then choose the type of advanced scan that you want to run: full, custom, or offline scan. The Full scan "checks all files and running programs on your hard disk" and can take more than one hour. The Custom scan lets you "choose which files and locations you want to check". And the Windows Defender Offline scan will restart your Windows 10 device and will try to find and remove malicious software before the operating system boots.
Back to the Virus & threat protection section, you also get access to the settings that control the way Windows Defender works on your PC. To get to them, click/tap on the Virus & threat protection settings link.
In the Virus & threat protection settings, you'll get a few switches and a few links for setting things the way you want to. You can turn the following features on or off:
-
Real-time protection - which "locates and stops malware from installing or running on your device". We firmly recommend you leave this feature on because it's your first shield against viruses. However, even if you do choose to disable it, after a short time, it will turn back on automatically.
-
Cloud-based protection - provides you access to the latest virus definitions available on Microsoft's servers from the cloud. It's recommended that you leave this option enabled.
-
Automatic sample submission - lets Microsoft fetch sample files from your Windows 10 device and analyze them for threats. If the files contain personal information, Microsoft promises to ask you about it. Otherwise, the samples are submitted without any other questions. It's recommended that you leave this feature turned on too because it helps Windows Defender react faster when new malware threats are found.
-
Exclusions - lets you choose files, folders, file types and processes that you don't want to be scanned by Windows Defender.
-
Notifications - allows or forbids Windows Defender to send you notifications about the latest antivirus scans, and/or about the apps blocked by Windows Firewall.
Finally, press the back arrow icon from the top left corner of the app to go back to the Virus & threat protection one last time. The last thing you'll see at the bottom of this page is an area called Protection updates. It's a place where you can "view information about your threat definition version, and check for updates".
That's pretty much all there is to know about the Virus & threat protection section from the Windows Defender Security Center app. Let's move on to the second section: Device performance & health. Click on the second page of this tutorial to continue reading.
