我无意中在我的 Windows XP 上打开了一个病毒，现在我无法打开 Windows 防火墙。
控制面板 > 单击 Windows 防火墙 > 出现此错误 - “由于未识别的问题，无法显示 Windows 防火墙设置”
我该怎么办？
（抱歉我的英语不好）

然后双击文件将内容合并到注册表中。双击后，将出现一条消息询问您是否确定，选择“是”或“确定”。将创建服务条目。重新启动 Windows（必须重新启动，否则后续步骤将不起作用）。
重新启动 Windows 后：单击“开始”>“运行”> 键入cmdclick好的。
在出现的窗口中，键入NETSH FIREWALL RESET并按 Enter。
转到控制面板（开始 > 控制面板）并双击“Windows 防火墙”。如果您没有看到“Windows 防火墙”，请单击控制面板左上角的“切换到经典视图”。您现在应该能够配置 Windows 防火墙的设置。
