知道有人在监视您的计算机是非常可怕的，但不知道如何判断它是否正在发生可能更可怕。但它确实会发生，如果你不积极阻止它，它也很可能发生在你身上。
如果有人正在监视您的计算机，他们可能已经这样做了一段时间，并且可能已经看到了您在做什么。他们可能窃取了您输入的密码、您在浏览器中打开的银行详细信息、存储在您插入的手机上的照片……不胜枚举。
如果您认为您的计算机已被劫持并且您所做的一切都被监视和/或跟踪，请继续阅读以了解如何验证您的计算机是否被监视，以及如何阻止它。
重要提示：(Important:)如果您已经知道有人正在积极监控您的计算机，断开互联网连接将立即终止他们的连接。(right
now)如果你能做到这一点，那就去做，然后通读这个页面，看看你可以在没有互联网的情况下做什么，以阻止他们在你下次连接到互联网时远程访问你。
我的电脑被监控了吗？(Is My Computer Being Monitored?)
以下是查看您的计算机是否被监视(computer is being monitored)的几种方法。
使用反间谍软件程序(Use An Anti-Spyware Program)
最好的方法之一也是一种预防措施——安装反间谍软件程序。他们检测间谍软件，通常还检测从开放网络端口到网络摄像头监控的所有内容，他们不仅检测到(detect )这些东西，还主动阻止它们。
提示(Tip)：您也可以通过网络浏览器自行阻止网络摄像头访问。(block webcam access yourself)
这里有一些不错的选择：
每次程序发现违规行为时，您都会收到警报，您通常可以启用阻止以防止再次发生，或者您会被告知程序已经为您阻止了它。
例如，如果键盘记录器将您的击键发送给另一个国家的黑客，反间谍软件工具可能会阻止它，然后告诉您。
提示：(Tip: )建议安装您从上面列表中选择的程序的免费试用版。它们大部分都是免费的，但是如果您想要更多功能（其中一个可能能够捕获您的计算机被远程监控），您可能需要获得完整版本。安装试用版可让您体验附加功能。
查看与 Internet 的活动连接(View Active Connections To The
Internet)
查看是否有人在监视您的计算机的下一个最佳方法是查看您的计算机与 Internet 上的某物建立的所有活动连接。
TCPView是在Windows中执行此操作的好方法。这非常简单，因为您可以看到计算机上的哪个进程连接到特定的远程地址。由于此处可能有很多条目，因此最好关闭您的网络浏览器并尽可能多地停止互联网活动。然后按远程端口(Remote Port)对列表进行排序，以找出任何不合适的地方。
如果
TCPView显示您的计算机正在被远程监控，请右键单击该进程以结束连接，然后进行一些研究以了解它是如何进入您的计算机的，这样您就知道如何永久删除它。
Wireshark数据包分析器是另一个也可以在Mac(Macs)上运行的选项，但学习曲线相当高。
检查开放端口(Check For Open Ports)
您的计算机通过网络端口连接到 Internet。常见的包括端口 80、21 和 443。但是根据您在计算机上安装的内容以及是否设置了端口转发规则，可能会打开更多端口。
打开大量端口（或您未使用的特定端口）的问题在于，有人可以利用它们与您的计算机远程通信以发送/接收病毒和其他文件、密码、图像等。
使用像这样(this one)的端口检查器来扫描网络上的端口(scan the ports on your network)。您可以通过登录到您的路由器或使用防火墙程序阻止它们(blocking them with a firewall program)来关闭端口。
提示(Tip)：路由器可以跟踪和监控互联网活动(track and monitor internet activity)。如果您是网络管理员并且想要这样做，请务必查看该文章。
查看已安装的程序(Review Installed Programs)
开始远程监控计算机的一种常见方式是通过恶意软件。也许您安装了一个您完全打算使用或您确实在积极使用的程序，或者该程序可能是作为捆绑软件安装的，而您甚至不知道它在那里。
无论如何，您应该检查当前安装的程序。如果有您不认识的应用程序或您不再使用的程序，请立即删除它们。最好的方法之一是使用IObit Uninstaller。
检查 Wi-Fi 安全性(Check The Wi-Fi Security)
并非所有 Wi-Fi 网络都需要密码，尤其是公共热点。如果您使用的是带Wi-Fi的笔记本电脑或台式机，请检查您连接的网络是否安全。
虽然这并不能立即说明您的计算机正在被监控，但如果不需要密码来使用它，它确实更有可能。一个开放的、未加密的 Wi-Fi(Wi-Fi)网络意味着该网络上的其他人更有机会看到您已连接到它(seeing that you’re connected to it)并监控您的无线流量以获取您在网站中键入的密码、您上传的图像等信息在线等
有关定位显示 Wi-Fi 安全性的Windows区域的说明，请参阅如何在 Windows 上查看已保存的 WiFi 密码。(How to View Saved WiFi Passwords on Windows)
可能需要监控您的计算机(Monitoring Your Computer Might Be Required)
这是不是一个可怕的想法！重要的是要认识到，根据您的情况，可能会有规定要求您监视您的活动。如果是这样，您可能无法阻止它。
例如，如果您在工作中使用计算机，则可能出于安全目的必须遵守员工监控策略。这可能意味着他们不仅关注您在网络上所做的事情，还关注您的计算机中插入的内容、您打开了哪些程序、您使用每个应用程序的频率、计算机进入睡眠状态的频率等。
如果这种情况发生在您身上，您可能无能为力，因为您可能无法安装反跟踪软件或从机器上删除程序。
公司通常会使用自己的间谍软件拦截器、病毒检测器和其他工具来保护公司的所有计算机和其他资源。因此，如果您在工作时担心外部监控，您可能不需要担心在您的个人计算机上安装某些东西（除非您在 IT 部门工作）。
How to Tell If Your Computer is Being Monitored
Knowing
that someone is monitoring your computer is рretty scary, but it’s perhaрs eνen
scarier not knowing how to tell if it’s even happening. But it does happen, and
could very well happen to yoυ too if yoυ’re not actively blocking it.
If
someone is monitoring your computer, they might have been doing so for some
time and could have seen much of what you were doing. They may have stolen
passwords you typed, bank details you opened in your browser, photos stored on
the phone you plugged in…the list goes on.
If
you think your computer has been hijacked and everything you’re doing is being
watched and/or tracked, keep reading to learn how to verify that your computer
is being monitored, and what to do to stop it.
Important: If you already know that someone is
actively monitoring your computer right
now, disconnecting from the internet will terminate their connection
instantly. If you can do that, go for it and then read through this page to see
what you can do without the internet to stop them remotely accessing you the
next time you connect to the internet.
Is My Computer Being Monitored?
Below are several methods for seeing if your computer is being monitored.
Use An Anti-Spyware Program
One
of the best methods is also a preventative measure – install an anti-spyware
program. They detect spyware but also usually everything from open network
ports to webcam monitoring, and they not only detect these things but also actively block them.
Tip: You can block webcam access yourself too, from your web browser.
Here
are some good options:
You’ll
be alerted each time the program finds a breach, and you can usually either
enable a block to prevent it from happening again or you’ll be told that the
program has already blocked it for you.
For
example, if a keylogger has been sending your keystrokes to a hacker in another
country, the anti-spyware tool will likely block it and then tell you so.
Tip: It’s recommended to install the free
trial of the program you pick from the list above. All of them are free for the
most part, but if you want more features (one of which might be able to catch
your computer being monitored remotely), you might need to get the full
version. Installing the trial gives you a taste of the additional features.
View Active Connections To The
Internet
The
next best way to see if someone is monitoring your computer is to view all of
the active connections your computer is making with something on the internet.
TCPView is a great way to do this in Windows. It’s pretty straightforward in that you see which process on your computer is connected to a specific remote address. Since there might be a lot of entries here, it’s best to shut down your web browser and cease as much internet activity as you can. Then sort the list by Remote Port to find anything out of place.
If
TCPView shows that your computer is being monitored remotely, right-click the
process to end the connection, and then do some research to learn how it got on
your computer so you will know how to delete it for good.
The Wireshark packet analyzer is another option that also runs on Macs, but the learning curve is rather high.
Check For Open Ports
Your
computer connects to the internet via network ports. Common ones include ports
80, 21 and 443. But depending on what you’ve installed to your computer and
whether you have port forwarding rules set up, there could be a lot more ports
open.
The
issue with having lots of ports open (or specific ones that you aren’t using)
is that someone could take advantage of them to communicate with your computer
remotely to send/receive viruses and other files, passwords, images, etc.
Use a port checker like this one to scan the ports on your network. You can close ports by logging into your router or blocking them with a firewall program.
Tip: A router can track and monitor internet activity. If you’re an admin on your network and you want to do that, be sure to check out that article.
Review Installed Programs
A
common way a computer starts being monitored remotely is through malware. Maybe
you installed a program that you fully intended on using or that you do
actively use, or maybe the program was installed as bundleware and you don’t
even know it’s there.
Regardless, you should do a check of the programs that are currently installed. If there are apps you don’t recognize or programs that you don’t even use anymore, promptly remove them. One of the best ways to do that is with IObit Uninstaller.
Check The Wi-Fi Security
Not all Wi-Fi networks require a password, especially public hotspots. If you’re using a laptop or a desktop with Wi-Fi, check the network you’re connected to to see if it’s secure.
While this doesn’t exactly explain right away that your computer is being monitored, it does make it more likely if a password isn’t necessary to use it. An open, unencrypted Wi-Fi network means that someone else on that network has a much better chance at seeing that you’re connected to it and monitoring your wireless traffic to pick up things like the passwords your type into websites, the images you upload online, etc.
See How to View Saved WiFi Passwords on Windows for directions on locating the area of Windows that shows the Wi-Fi security.
Monitoring Your Computer Might Be Required
Isn’t
that a scary thought! It’s important to realize that depending on your
situation, there might be rules in place that demand that your activities be
watched. If so, there’s likely little you can do to stop it.
For
example, if you use a computer at work, there’s probably an employee monitoring
policy that has to be upheld for security purposes. This might mean that
they’re watching not only what you do on the web but also what gets plugged
into your computer, which programs you open, how often you’re using each
application, how often your computer goes to sleep, etc.
If
this is happening to you, there’s likely not much you can do because you
probably can’t install anti-tracking software or remove programs from the
machine.
It’s
common for companies to include their own spyware blockers, virus detectors,
and other tools to protect all of the company’s computers and other resources.
So you probably don’t need to worry about installing something on your
individual computer (unless you work in the IT department) if you’re worried
about external monitoring while you’re at work.
