Welcome, reader, to our ContainerTag.js removal guide. The following instructions will aid you in removing the unwanted software from your PC.

Welcome to the ContainerTag.js removal guide. If you are reading this page, most probably you have had a close encounter with dozens of ads, pop-ups, and banners on your Chrome or Firefox browser. The reason for this is an adware program called ContainerTag.js that is delivering these annoying popping messages directly on your screen and what’s more, it has probably been installed on your system unnoticed. Fortunately, our team has come up with some very useful information about this software, the way it operates and the way you can uninstall it from your computer. If you feel annoyed by the adware activity that his happening on your screen, here you are going to find a detailed guide that will help you remove it. And if you want to prevent such programs from getting installed on your PC again, we are going to explain to you how to protect your system. So let’s not waste more time and take a look at the information below.

What is ContainerTag.js ?

As we just said above, ContainerTag.js falls in the category of adware and this means that this program specializes in displaying all sorts of ads, pop-ups, banners and boxes on your screen while you are browsing the web. However, this could be quite a disturbing program for some users. As a result of the adware’s activity, some people may experience some undesired changes that may directly interfere with their normal browsing. For example, adware may change your homepage without your approval, or it may replace your default search engine with another one, which may constantly redirect your searches to sponsored messages, popping boxes, notifications, and unknown websites. This is something that some people can’t cope with and may feel heavily irritated by.

Moreover, some users who are facing these strange changes on their PC for the first time may think that they have been infected by a virus or some malware. But we have good news for those of you who are concerned about their safety – ContainerTag.js is not a virus. In general, adware programs are not identified as security threats and unlike viruses or malware like Ransomware, Trojans, spyware and others, these programs do not contain malicious scripts designed to do harm on your system. What they do is mostly interrupt your browsing with annoying and unstoppable ads, but nothing more than that. Real malware, however, would most probably destroy your data, infect other devices, create security breaches and encrypt your valuable files. None of this could be done by adware. But still, there are some behavioral traits and distribution methods that have gained ContainerTag.js the fame of a potentially unwanted program that users may wish to uninstall.

First of all, the way adware gets installed on your PC may seem a bit tricky. But this is mostly because of your negligence during the software installation process rather than a delusive tactic. Usually, programs like ContainerTag.js can be found in software bundles where they are packed with other applications that are distributed for free. This is a common practice of many software developers who include adware in their software with the idea of earning money from the paid ads and sponsored pages through the Pay-Per-Click scheme. You can get such bundles if you download software from torrents, file sharing sites, spam emails, open source download platforms, direct downloads and installation managers. What is more important is, that you can avoid installing the adware that is packed with your desired software only if you click the right installation option. Most users simply follow the default installation when they run the setup. But this option installs the entire bundle as it is and doesn’t give them the opportunity to manually select or deselect the programs that are packed inside of it. For this, they need to click the custom/advanced/manual option during the setup. It will display a detailed menu with the desired program and all the additionally placed software. There they can prevent the potentially unwanted programs from getting installed with just one click.

Why is it a good idea to remove ContainerTag.js from your PC?

You already know that ContainerTag.js is not a threat, but we cannot say the same about the pop-ups, ads and randomly generated pages you may land on. With the increased popularity of the online advertising methods, malicious hackers are also trying to use different delusive techniques to hide and distribute their malware. One of these methods is malvertising, where seemingly harmless ads, pop-ups, links or web pages may contain infections like viruses, Ransomware, Trojans and whatnot. It is may happen that such fake ads can somehow sneak among the real ones you see on your screen and if you click on them, you may get infected with malware. This is one of the main reasons why we advise our readers not to click on randomly generated messages on their screen. And if they want to eliminate the risk of insecure ads being displayed on their screen, they should always pay attention while browsing the web and avoid sketchy content as much as possible. It may also be a good idea to entirely remove the adware from your system and ensure you are not exposed to unnecessary amount of ads.
