主机文件位置

锁定 Hosts(Lock Hosts)文件以防止劫持
想象一下点击www.thewindowsclub.com并在您的浏览器中看到一个完全不同的网站加载。恶意软件(Malware)可以通过更改您的 Hosts 文件来重定向您计算机上的Web地址。这称为主机文件劫持(Host File Hijack)。
为了防止主机(Host)文件劫持，您可以导航到它，右键单击它，选择属性(Properties)并将其设为只读(Read-only)文件。这将锁定您的 Hosts 文件并防止任何人或任何恶意软件对其进行写入。
使用 Hosts 文件阻止网站
要使用Hosts File(Hosts File)阻止网站，只需添加以下条目：
127.0.0.1 blocksite.com
虽然我不这样做，但许多用户喜欢手动添加条目以阻止打开一个或多个特定网站。其他人则喜欢从mvps.org(mvps.org)等知名来源下载和使用 List ，以添加阻止恶意软件站点打开的条目。

- 打开资源管理器
- 导航(Navigate)到 System32driversetc 位置

现在让我们进行详细的解释。
要编辑Hosts文件，请导航到以下文件夹位置：
C:\Windows\System32\drivers\etc\
在这里，您将看到 Hosts 文件。右键单击它并选择记事本(Notepad)。进行更改并保存(Save)。
但有时，即使您使用管理凭据登录，您也可能会收到以下错误消息：
Access to C:\Windows\System32\drivers\etc\ hosts was denied
或者

在这种情况下，请在开始(Start)搜索中键入记事本(Notepad)，然后右键单击记事本(Notepad)结果。选择以管理员身份运行(Run as administrator)。
打开Hosts文件，进行必要的更改，然后单击Save。

In short, it’s the only Hosts Manager that you will even need. You can download it from its home page.
