我唯一打开的互联网连接就是这个网站。
我运行了 SpyBot,它删除了大约 60 多个项目。这是我运行它之后的结果。我的视频速度一直变慢,所以我正在尝试解决这个问题。
答案1
正如其他人提到的,您的输出似乎没有任何明显问题。解决视频问题可能需要另一个问题。就 Chrome 而言:
防止 Chrome 在后台运行
chrome://settings
在 Chrome 浏览器中转到。- 单击
Show advanced settings...
页面底部的链接。 - 在下面系统在高级设置底部附近的标题中,取消选中
Continue running background apps when Google Chrome is closed
。
调查个别连接
“……不过既然无法阻挡,我猜他们是安全的。”
成功阻止 Windows 防火墙中的端口范围意味着创建 4 条规则:TCP Incoming
、、和UDP Incoming
。默认情况下,所有未明确允许的传入连接都会被阻止,而所有未明确阻止的传出连接都会被允许。但是,可能存在允许传入连接的规则。阻止规则几乎总是优先于允许规则,因此您可以创建传入规则以获得更好的确定性。如果出现TCP Outgoing
UDP Outgoing
通过传递您的防火墙规则,可能值得调查。
话虽如此,如果有潜在有害程序 (PUP) 或恶意软件,最好将其删除,而不是阻止连接。许多人使用的一个好程序是Malwarebytes。它的实时扫描功能是需要付费的,但作为手动病毒扫描程序使用则是免费的。
我愿意假设如果你做了netstat -fb
(或netstat -fnb
仅针对 ip),它会显示你的“xx-in-x###”域实际上是“xx-in-x###”。1e100.net'. 根据http://whois.domaintools.com/1e100.netwhois 上显示,Google 拥有 1e100.net 域名。信息与http://whois.domaintools.com/google.com注册信息。我认为这些是安全的,尤其是考虑到谷歌Chrome 浏览器。
其他一些地址(例如 93.184.216.169 和 205.185.208.18)可能不太友好。例如,205.185.208.18 域名是myinfotopia.com
(Chrome 的工具栏)。chrome://extensions/
如果这是非故意的,请检查您的 Chrome 浏览器。如果您使用 的输出更新您的帖子netstat -fb
,将更容易提供帮助。
答案2
首先,直奔主题,你的视频问题可能与你打开的连接数无关,除非你正在运行 torrent 客户端或其他参与创建大量连接的协议的客户端。我会检查你的视频卡驱动程序、编解码器、闪存安装等。
也就是说,根据 netstat 帮助,-b 选项:
-b 显示创建每个连接或监听端口所涉及的可执行文件。在某些情况下,众所周知的可执行文件承载多个独立组件,在这些情况下,将显示创建连接或监听端口所涉及的组件的顺序。在这种情况下,可执行文件名称位于底部的 [] 中,顶部是它调用的组件,依此类推,直到到达 TCP/IP。请注意,除非您拥有足够的权限,否则此选项可能非常耗时,并且会失败。
此选项不过滤连接列表,它仅显示进程信息。
我认为您对现有的连接数量感到惊讶,但这并不罕见。未过滤的 netstat 输出通常非常大。
连接用于进程间通信(进程 A 想要与进程 B 通信),因此您的连接可能具有端点,这些端点要么是 127.0.0.1,要么是系统默认接口的 IP 地址。这些端口不一定可供其他计算机上的任何人访问。本地端口为 127.0.0.1 的进程只能由本地 PC 连接,因此防火墙不会阻止它们。
