理想情况下，bfsvc.exe是用于引导文件服务实用程序的^{(Boot File Servicing Utility)}Windows操作系统文件。它对您的计算机的运行至关重要，但前提是它是合法的 bfsvc.exe。

我添加了上述条款，因为虽然 bfsvc.exe 应该是一个必不可少的系统文件，但木马病毒也会伪装成这个文件。此病毒会将您的计算机添加到由全球数千万其他受感染计算机组成的ZeroAccess僵尸网络。^(ZeroAccess)当您成为僵尸网络的一部分时，远程黑客将使用您的计算机进行协同网络攻击，例如DDoS。

现在的问题是，一方面，bfsvc.exe 可能是您不应该删除的重要Windows系统文件。^(Windows)另一方面，它也可能是您必须从系统中删除的危险木马病毒。^(Trojan)

本文向您展示如何判断您是否被感染或只有合法文件。如果您的 PC 被感染，我们还将向您展示如何从您的计算机上完全卸载它。

什么是 bfsvc.exe 病毒？

如前所述，bfsvc.exe 文件可能是将您的计算机添加到 ZeroAccess 僵尸网络的病毒。黑客使用您系统的资源和僵尸网络中其他人的资源来挖掘比特币^(Bitcoin)并攻击其他系统。

除了促进比特币^(Bitcoin)挖掘之外，该病毒还会攻击Windows 注册表^{(Windows Registry)}，以防止在您每次启动系统时检测和运行。用户发现很难从他们的计算机中删除 bfsvc.exe 病毒，因为它可以使用先进的技术禁用您的防病毒软件。

通过停用您的防病毒软件，它会使您的计算机容易受到其他类似病毒的攻击。bfsvc.exe 实际上会在您的硬盘驱动器上安装这些病毒。

黑客还可能窃取受此病毒感染的系统上的数据。如果不加以检查，bfsvc.exe 病毒最终会导致您的计算机崩溃。

如何区分合法的 bfsvc.exe 和病毒

按^(Press)Windows键并搜索 bfsvc.exe。右键单击搜索建议中的文件，然后点击 Open file location。

右键单击^{(Right-click)}目录中的文件并选择Properties。在这里，导航到 详细信息^(Details)选项卡并检查文件的属性。

首先，恶意 bfsvc.exe 文件会比合法文件大得多。引导文件服务实用程序^{(Boot File Servicing Utility)}bfsvc.exe的大小应为72 kb以上。如果您系统上的文件不是这个大小，您可能需要删除它。

bfsvc.exe 文件的位置是该文件合法性的另一个证明者。理想情况下，它应该位于%WINDOWS%目录的子文件夹中。如果它位于不同的位置，则可能是恶意的。

在 bfsvc.exe 文件属性中要注意的另一件事是发布者。除了微软公司^{(Microsoft Corporation)}之外，这里的任何东西都是危险 信号。

如何删除 bfsvc.exe 病毒

如果您确定您计算机上的 bfsvc.exe 是恶意的，您必须立即将其删除。您使用防病毒软件从系统中删除 bfsvc.exe 病毒。

但是，由于此病毒的性质，您可能无法使用常规方法将其删除。在这种情况下，您必须先以安全模式启动计算机^{(boot your computer in Safe Mode)}。

在安全模式下^{(Safe Mode)}，您现在可以使用可靠的防病毒软件^{(reliable antivirus software)}诊断您的计算机。检测到病毒后，立即使用防病毒程序将其删除。

Bfsvc.exe: Is it Safe or a Virus? Guide to remove it permanently

Ideally, bfsvc.exe is the Windows operating system file for the Boot File Servicing Utility. It’s vital to your computer’s functioning, but that’s only if it’s the legitimate bfsvc.exe.

I added the above clause because while bfsvc.exe should be an essential system file, a Trojan horse virus also disguises as this file. This virus adds your computer to a ZeroAccess botnet of tens of millions of other infected computers around the globe. When you’re part of a botnet, remote hackers will use your computer to carry out coordinated cyberattacks, such as DDoS.

The issue now is that on the one hand, bfsvc.exe could be a vital Windows system file that you shouldn’t delete. On the other hand, it could also be a dangerous Trojan virus that you must remove from your system.

This article shows you how to tell if you’re infected or only have a legitimate file. If your PC is infected, we’ll also show you how to completely uninstall it from your machine.

What is the bfsvc.exe virus?

As mentioned earlier, the bfsvc.exe file could be a virus that adds your computer to a ZeroAccess botnet. The hackers use your system’s resources and that of others in the botnet to mine Bitcoin and attack other systems.

Apart from facilitating Bitcoin mining, the virus also attacks the Windows Registry in order to prevent detection and run every time you start up your system. Users find it tough to remove the bfsvc.exe virus from their computers because it can disable your antivirus using advanced technology.

By deactivating your antivirus, it makes your computer vulnerable to other similar viruses. The bfsvc.exe actually installs these viruses while living on your hard drive.

The hackers will also possibly steal data on systems infected by this virus. If left unchecked, the bfsvc.exe virus will end up crashing your computer.

How to differentiate between the legitimate bfsvc.exe and the virus

Press the Windows key and search for bfsvc.exe. Right-click on the file from the search suggestions and hit Open file location.

Right-click on the file in the directory and select Properties. Here, navigate to the Details tab and check the properties of the file.

Firstly, the malicious bfsvc.exe file would be considerably larger than the legitimate one. The Boot File Servicing Utility bfsvc.exe should be from 72 kb in size. If the file on your system is not in this size, you may want to remove it.

The location of the bfsvc.exe file is another teller of the legitimacy of the file. Ideally, it should reside in a subfolder in the %WINDOWS% directory. If it’s in a different location, it’s probably malicious.

Another thing to look out for in the bfsvc.exe file properties is the Publisher. Anything here other than Microsoft Corporation is a red flag.

How to remove the bfsvc.exe virus

If you determine that the bfsvc.exe on your computer is malicious, you must immediately get rid of it. You use antivirus software to remove the bfsvc.exe virus from your system.

However, due to this virus’s nature, you may not be able to remove it using regular methods. In this case, you have to boot your computer in Safe Mode first.

When in Safe Mode, you can now diagnose your computer using reliable antivirus software. On detection of the virus, remove it immediately using the antivirus program.
