微软^(Microsoft)喜欢迷惑他们的用户，因为大多数人都发现使用Windows 8。不仅Windows 8令人困惑，而且微软^(Microsoft)在每次更新时都在不断改变新操作系统的工作方式。

Windows 7 和Windows 8^{(Windows 8)}最令人困惑的方面之一是Microsoft提供的防病毒解决方案。您应该^(Should)使用 Windows Defender还是Microsoft Security Essentials？有什么不同？还有什么是Microsoft 安全扫描程序^{(Microsoft Safety Scanner)}，为什么它与其他工具防病毒工具不同？

在本文中，我将解释Windows 7和Windows 8中不同防病毒工具之间的差异以及您可以在哪里使用每个工具。值得庆幸的是，Windows 10中的情况更加清晰。

Windows Defender与Security Essentials

Windows Defender最初被称为Microsoft AntiSpyware，最终包含在Windows Vista和Windows 7中。您还可以下载适用于Windows XP和Windows Server 2003的^{(Windows Server 2003)}Windows Defender，尽管现在您似乎不能再下载了。您仍然可以下载Windows Defender Offline，它与Windows Defender不同，我将在下面进行详细说明。

关于Windows Defender^{(Windows Defender)}的主要注意事项是它仅在Windows 7及更低版本中防止间谍软件。这就是为什么您总是需要在Windows 7^{(Windows 7)}及更早版本中使用另一个单独的防病毒程序。可以下载Microsoft Security Essentials来替换^{(Microsoft Security Essentials)}Windows Defender，因为它可以捕获间谍软件并扫描病毒。安装后，它将完全禁用Windows Defender。

Windows Defender Offline基本上正如其名称所暗示的那样：Windows Defender的离线版本，您可以在 CD、DVD或USB驱动器上下载并运行它。您可以在操作系统启动之前使用Windows Defender Offline扫描病毒，这可以极大地帮助您删除非常狡猾的恶意软件或间谍软件。^{(Windows Defender Offline)}同样^(Again)，它不会捕获病毒，只会捕获间谍软件。

在Windows 8和Windows 10中，Windows Defender已升级为能够进行病毒扫描。它几乎与Microsoft Security Essentials中的扫描仪相同，这就是为什么Microsoft不允许您在Windows 8/10Security Essentials的原因。它还使用相同的病毒定义，并且用户界面几乎完全相同。

在Windows 8/10Microsoft Security Essentials名称可能更有意义，但他们决定保留Windows Defender名称，这会引起一些混乱。

下面是 Windows Defender 的当前状态：^{(So here’s the current state of Windows Defender:)}

– 内置于Windows Vista和Windows 7中，仅可防御间谍软件。可与Microsoft Security Essentials一起使用。

– 内置于Windows 8和 10，但包括病毒扫描程序。不能与Microsoft Security Essentials一起使用。

– 在Windows XP上，您可以使用Microsoft Security Essentials，因为Window Defender不再可用。

– Windows Defender Offline可以在任何版本的Windows上使用，一直到Windows 10

微软安全扫描仪

Microsoft Safety Scanner是^{(Microsoft Safety Scanner)}Microsoft的另一款防病毒工具，类似于Windows Defender Offline，因为它是独立的病毒和恶意软件扫描程序。它基本上是一种按需扫描程序，如果病毒已禁用或干扰您当前的防病毒程序，您可以尝试将其用作最后的手段。

与Windows Defender Offline不同，您仍然在Windows内部运行Microsoft Safety Scanner ，而不是使用启动媒体。您可以简单地下载包含最新签名的EXE文件并运行它。由于它是按需扫描程序，因此每次要使用它时都应始终重新下载该程序，否则您将无法使用最新的病毒签名进行扫描。这些文件每天都会使用最新的签名更新多次。

因此，希望这对Microsoft^(Microsoft)提供的一些安全工具有意义。还有其他工具，但它们不太常见，我们不会在本文中提及它们。Windows Defender、Security Essentials和Safety Scanner是可用于在Windows XP、Vista、7、8 和 10 中删除病毒和恶意软件的主要工具。尽情享受吧！

Windows Defender vs. Security Essentials vs Safety Scanner

Microsoft loves to confuse their usеrs aѕ most people have found out using Windows 8. Not only was Windows 8 confusing, but Microsoft keeps changing how the new opеrating system works with every update.

One of the most confusing aspects to Windows 7 and Windows 8 is the anti-virus solutions provided by Microsoft. Should you use Windows Defender or Microsoft Security Essentials? What’s the difference? Also what is Microsoft Safety Scanner and why is that different from the other tool anti-virus tools?

In this article, I’ll explain the differences between the different anti-virus tools in Windows 7 and Windows 8 and where you can use each tool. Thankfully, things are clearer in Windows 10.

Windows Defender vs Security Essentials

Windows Defender was originally known as Microsoft AntiSpyware and was eventually included with Windows Vista and Windows 7. You could also download Windows Defender for Windows XP and Windows Server 2003, though it seems that now you can’t anymore. You can still download Windows Defender Offline, which is different than Windows Defender and I’ll explain more below.

The main thing to note about Windows Defender is that it only protects against spyware in Windows 7 and below. That’s why you always needed another separate anti-virus program in Windows 7 and earlier. Microsoft Security Essentials could be downloaded to replace Windows Defender since it could catch spyware and scan for viruses. Once installed, it would disable Windows Defender altogether.

Windows Defender Offline is basically exactly what the name suggests: an offline version of Windows Defender that you download and run off a CD, DVD or USB drive. You can use Windows Defender Offline to scan for viruses before the operating system boots up, which can greatly help your chances of removing a very sneaky piece of malware or spyware. Again, it won’t catch viruses, just spyware.

In Windows 8 and Windows 10, Windows Defender was upgraded to be able to do virus scans also. It pretty much is the same scanner as the one in Microsoft Security Essentials and that is the reason why Microsoft does not allow you to install Security Essentials on Windows 8/10. It also uses the same virus definitions and the user interface is pretty much exactly the same.

It might have made more sense to just keep the name Microsoft Security Essentials in Windows 8/10, but they decided to stay with the Windows Defender name, which causes some of the confusion.

So here’s the current state of Windows Defender:

– Comes built-in with Windows Vista and Windows 7 and only protects against spyware. Can be used with Microsoft Security Essentials.

– Comes built-in with Windows 8 and 10, but includes a virus scanner. Cannot be used with Microsoft Security Essentials.

– On Windows XP, you can use Microsoft Security Essentials as Window Defender is no longer available.

– Windows Defender Offline can be used on any version of Windows all the way up to Windows 10

Microsoft Safety Scanner

Microsoft Safety Scanner is another anti-virus tool from Microsoft that is similar to Windows Defender Offline in that it is a standalone virus and malware scanner. It’s basically an on-demand scanner that you can try to use as a last resort if the virus has disabled or interfering with your current antivirus program.

Unlike Windows Defender Offline, you still run Microsoft Safety Scanner inside of Windows rather than using boot media. You can simply download the EXE file which contains the latest signatures and run it. Since it’s an on-demand scanner, you should always re-download the program every time you want to use it otherwise you won’t be scanning with the latest virus signatures. The files are updated multiple times a day with the latest signatures.

So hopefully that makes sense of some of the security tools provided by Microsoft. There are also other tools, but they are less common and we won’t mention them in this post. Windows Defender, Security Essentials and Safety Scanner are the main tools you can use for removing viruses and malware in Windows XP, Vista, 7, 8 and 10. Enjoy!
