How to Remove ContainerTag.js “Virus” from Chrome/Firefox

I wrote this article to help you remove ContainerTag.js. This ContainerTag.js removal guide works for Chrome, Firefox and Internet Explorer.

ContainerTag.js is a member of the adware family and, as such, it is something you don’t have to host on your machine. Adware pieces are intrusive, secretive and incredibly irritating but they are also potentially dangerous. An adware can cause serious damage if given the time to operate. Luckily, this malware family is known to be relatively easy to remove. In comparison with other threats like ransomware pieces or Trojans, ContainerTag.js is a piece of cake. But no infection should be underestimated. ContainerTag.js is still a parasite and the sooner you get rid of it the better. If you let it stay you will regret it very soon. ContainerTag.js can and will use every minute to bombard you with issues.

For starters, the adware enters your system in complete and utter silence but, once there, it is impossible not to notice it. Why? Because it meddles with your machine. It makes changes which you neither approved nor were informed of. The thing is ContainerTag.js doesn’t need your permission to operate. It makes reshuffles as it sees fit. For example, your browser settings get altered. You open your browser one day only to find that both your homepage and favorite search engine have been replaced. Aside from that, your browsing experience is not the same anymore. You are unable to search the Web normally due to the adware`s presence. First of all, you get redirected to unknown pages all the time. You try loading a particular website and all of a sudden you end up visiting another very shady one. Also, you are forced to deal with an avalanche of ads on daily basis.

All kinds of pop-ups, commercials, deals, coupons, best prices, video ads, etc. will be covering your whole screen all the time. Can you work with such conditions? We highly doubt it you could get any work done with the constant redirections and the never-stopping ad flood. But there is more. The adware`s shenanigans don’t only disturb you. They expose you to danger. You see, these numerous ads are sponsored. You know what this means, right?

Crooks use them to generate Web traffic to specific pages so they could gain profit. And their profits come only at your expense. They are using the pay-per-click mechanism so every time you click on an ad you help hackers fill their pockets. And the worst part is that you risk filling your own machine with more infections in the process. Most of these ads conceal other threats which are only one click away from attacking you. You can find your PC brimming with parasites in no time. And if that happens how long do you think it will last before the Blue Screen of Death appears? One threat you can tackle but 5 of 10… not so much. Don’t take that risk.

Your computer is already suffering due to this adware`s presence. It is slow, it crashes a lot, your browser freezes, and so on and so on. And to top it all, ContainerTag.js starts spying on you from the moment it slithers in. It monitors everything – from IPs, accounts, and emails to usernames, passwords, and browser-related data. Your financial information is not safe either. All of this falls in the adware`s hands and it gives it to the crooks behind it. This is how this threat jeopardizes your privacy and exposes your personal details to strangers. Strangers who won`t think twice before they sell it or use for their malicious purposes. Don’t sit around waiting for this to happen because if it does, there is no going back. Use our removal guide below and delete this nasty adware from your system.

However, this time you are lucky and a free removal guide is available to help you. But this is not always the case. You have to make sure there won`t be another infection. First, get yourself a reliable anti-malware program, keep it updated and scan your PC regularly to be sure it is clean. Second, do your best to prevent a second attack. These infections use trickery and deceive to dope you into allowing them to enter. Yes, they absolutely need your approval and they go out of their ways to get it. Some of their tactics include freeware/shareware bundles, spam email messages, corrupted links, etc. You should always be on the alert while online. For example, when you are installing a program always opt for the Advanced settings in the Setup Wizard. They give you complete control and you can deselect any tool which is attached to the package but which you don’t want to get.

Also, reading the Terms and Conditions is a must unless you want to agree with something you are completely against. Stay away from unverified sources and illegitimate pages. And last but not least, don’t open any email you get lightly. Especially if you don’t know who sent it to you. Remember that all infections need is your carelessness without which you won`t give them green light. So, don’t provide it. Preventing an infection is much easier that dealing with it while it is wrecking your machine.
