[Bug]: 莫名其妙出现开启自动配置系统代理，无法访问国内网站(规则模式)

[GeWuYou]

预期情况

之前是既能访问国内网站也能访问国外网站

实际情况

实际上就出现开启自动配置系统代理后，只能访问国外网站，国内的访问不了，使用pac模式虽然能解决，但出现使用微信和钉钉提示网络异常，而且在pac模式下，下载东西会出现：已存在的连接被远程主机强行关闭。这通常由远程主机上的同级程序突然中止、主机重启或远程主机使用了“强制关闭"造成。只有在开启自动配置系统代理且为全局代理的情况下网络才是正常的。
原先情况：自动配置系统代理(规则模式)国内国外网站都能访问
现在情况：

1. 自动配置系统代理(规则模式)国内网站无法访问，国外可以
2. 自动配置系统代理(全局模式)国内国外网站都能访问，钉钉微信正常使用
3. pac模式(规则模式)国内外网站都能访问但钉钉微信微信无法使用
4. pac模式(全局模式)国内外网站都能访问，钉钉微信正常使用

复现方法

就突然出现的这个问题，昨天还好好的，我啥也没动。

额外信息

之前我使用clash也出现过这个问题，怎么折腾也解决不了，索性就换v2rayN，解决了这个问题，但今天又出现这个问题了，更新到最新版本也解决不了，所以很奇怪，有大佬知道咋回事吗？

我确认已更新至最新版本

• 是

我确认已查询历史issues

• 是

换一个思路，如果你只是需要浏览器访问外网，其实可以试一试 chrome 插件 Proxy SwitchyOmega 3 (ZeroOmega)

这个问题是当我选择多服务器最低延迟时会出现，当我选择某个节点设置为活动服务器，这种情况就不会出现

已经解决，请检查电脑是否安装了卡巴斯基等杀毒软件，我之前是装了卡巴斯基，然后没有添加白名单，所以导致这个问题的。
