互联网上的一个新趋势是使用网站在访问者不知情的情况下挖掘加密货币。结果，访问者的网络浏览器^{(web browser)}变慢，网络浏览体验^{(browsing experience)}变得非常令人沮丧。如果您使用谷歌浏览器^(Chrome)并且您的计算机的处理器使用率^{(processor usage)}上升很多，那么在访问特定网站时，您必须阅读这篇文章。我们解释了为什么会出现此问题以及您需要做什么来保护自己：

问题：当我访问特定网站时，谷歌浏览器的^{(Google Chrome)}CPU 使用率^{(CPU usage)}上升

在过去的几个月里，很多用户抱怨这个问题：当你尝试访问一个特定的站点时，谷歌浏览器的处理器 ( ^{(Google Chrome)}CPU ) 使用率猛增到 45%、75%、90% 或更多。正在使用的计算机或笔记本电脑的声音变得更大，因为通风开始冷却处理器。这也导致功耗^{(power consumption)}增加。

当您关闭该网站的标签时，一切都会恢复正常。这最近也发生在我们身上，在一两个网站上。下面，您可以看到Google Chrome的^{(Google Chrome)}CPU 使用情况^{(CPU usage)}，只打开了一个标签页并加载了一个网站。

如果您问我们，这很多，尤其是在使用功能强大的台式计算机^{(desktop computer)}时，具有充足的CPU 能力^{(CPU power)}。

为什么会这样？因为加密货币挖矿^{(cryptocurrency mining)}！

^{(Google Chrome)}与Microsoft Edge^{(Microsoft Edge)}或Firefox等其他 Web 浏览器相比， ^(Firefox)Google Chrome倾向于使用更多的处理资源。但是，如果此问题仅在访问特定网站时出现，并且在您关闭加载它们的选项卡时消失，则此行为是不正常的，并且CPU 使用率高不是^{(CPU usage)}谷歌浏览器的^{(Google Chrome's)}错。您很可能是加密货币挖掘^{(cryptocurrency mining)}的受害者。您正在访问的网站将Javascript^(Javascript)加载到您的网络浏览器^{(web browser)}中，该浏览器会挖掘加密货币或显示^{(cryptocurrency or displays)}受感染的广告，这些广告使用您的计算机硬件来挖掘加密货币^{(mining cryptocurrency)}. 为什么有些网站会这样做？通过使用访问者的计算资源来赚钱，因为加密货币可以转换为现金

这是不道德的，但目前还没有禁止这种做法的法律。

如何解决问题：为Google Chrome安装 No Coin^{(Install No Coin)}

No Coin是由^{(No Coin)}Rafael Keramidas创建的开源项目。它会自动阻止加密货币挖掘^{(cryptocurrency mining)}，以便您在浏览网页时免受这种做法的影响。Opera内置了这个工具^{(tool built-in)}，而Google Chrome有一个任何人都可以安装的No Coin扩展。在Google Chrome中，转到此处^{(go here)}，然后单击或点击“添加到 Chrome”。^{("Add to Chrome.")}

单击“添加扩展程序”^{("Add extension.")}，确认您要将此扩展程序添加到浏览器。

您会被告知Google Chrome中添加了No Coin ，您可以在顶部地址栏^{(address bar)}附近看到它的图标。您可以在下面的屏幕截图中看到它突出显示。

当此图标显示在Google Chrome中时，您将免受加密货币挖掘^{(cryptocurrency mining)}，因为此扩展程序会自动阻止用于此做法的脚本和广告。

No Coin 真的有用吗？

为了进行快速测试，我们访问了在Google Chrome中添加No Coin后进行加密货币挖掘^{(cryptocurrency mining)}的同一网站。您可以看到，处理器使用率^{(processor usage)}从 45%（在第一个屏幕截图中）下降到 3%（下面的屏幕截图）。这是一个相当大的改进，可以带来出色的用户体验^{(user experience)}。

您对挖掘加密货币的网站多久遇到一次问题？

在结束本教程之前，请与我们分享您在进行加密货币挖掘^{(cryptocurrency mining)}的网站方面的经验。你^(Did)遇到过很多吗？当您访问此类网站时，谷歌浏览器^{(Google Chrome)}的行为如何？在下面发表评论^(Comment)，让我们讨论。

Fix problem: Google Chrome uses a lot of processor (CPU) when I visit a website

A new trend on the internet іs that of using websites to mine cryptocurrencіes without the knowledge of theіr visitors. As a result, the visitor's web browser gets slow, and the web browsing еxpеriеnce bеcomes incredibly frustrating. If you use Google Chrome and yoυr comрutеr's processor usage goes up a lot, when viѕiting a specific website, then you must read this artiсle. We еxplain why this iѕsue occurs and what you need to do, to protect yourself:

The problem: The CPU usage of Google Chrome goes up when I visit a particular website

In the last few months, many users complained about this problem: when you try to visit a specific site, the processor (CPU) usage of Google Chrome shoots up to a large percentage like 45%, 75%, 90% or more. The computer or laptop being used gets louder because the ventilation kicks in to cool the processor. This also leads to increased power consumption.

When you close the tab with that website, everything goes back to normal. This recently happened to us too, on a website or two. Below, you can see the CPU usage of Google Chrome, with only one tab open and one website loaded.

This is a lot if you ask us, especially when using a powerful desktop computer, with plenty of CPU power.

Why does this happen? Because of cryptocurrency mining!

Google Chrome tends to use more processing resources than other web browsers like Microsoft Edge or Firefox. However, if this problem takes place only when visiting specific websites and it goes away when you close the tabs where they are loaded, then this behavior is not normal, and it is not Google Chrome's fault for the high CPU usage. Most probably, you are a victim of cryptocurrency mining. The website(s) that you are visiting loaded a Javascript into your web browser that mines for cryptocurrency or displays compromised ads that use your computer's hardware for mining cryptocurrency. Why do some websites do this? To make money by using the computing resources of their visitors, as cryptocurrencies can be converted into cash

It is not moral, but there are no laws against this practice, yet.

How to fix the problem: Install No Coin for Google Chrome

No Coin is an open-source project that was created by Rafael Keramidas. It blocks cryptocurrency mining automatically so that you are protected from this practice when browsing the web. Opera has this tool built-in, while Google Chrome has a No Coin extension that anyone can install. In Google Chrome, go here, and then click or tap "Add to Chrome."

Confirm that you want to add this extension to your browser by clicking "Add extension."

You are informed that No Coin was added to Google Chrome, and you can see its icon near the address bar on the top. You can see it highlighted in the screenshot below.

When this icon is displayed in Google Chrome, you are protected from cryptocurrency mining, because this extension automatically blocks the scripts and the ads that are used for this practice.

Does No Coin work, for real?

To make a quick test, we visited the same website that does cryptocurrency mining, after No Coin was added to Google Chrome. You can see, that the processor usage decreased from 45% (in the first screenshot) to 3% (the screenshot below). That is a considerable improvement that leads to an excellent user experience.

How often do you have issues with websites that mine for cryptocurrency?

Before closing this tutorial, share with us your experience with websites that do cryptocurrency mining. Did you encounter many of them? How did Google Chrome behave when you visited such websites? Comment below and let's discuss.
