Tail Box browser hijacker Removal Guide

What is Tail Box browser hijacker?

Tail Box is a browser-hijacking app that tracks user data and shows ads

Tail BoxTail Box is a potentially unwanted application that changes browser settings to show ads

Tail Box is one of many potentially unwanted applications[1] that one could find installed on Google Chrome, Mozilla Firefox, MS Edge, or another browser. It comes in the form of an extension – a type of software that attaches itself to the web browser to function. The app specializes in the so-called hijacking, where it takes over the browser in order to implement its own settings in order to perform its activities.

How the hijacker operates

The deceptive aspect of the Tail Box hijacker starts with its distribution. While some users might install the extension intentionally, believing that it might be useful, others never remember installing it in the first place. This happens due to software bundling – a distribution technique that tricks many people into accepting optional programs during the installation process of the freeware.

Once installed, the browser hijacker would immediately change the homepage and the new tab function by appending tailsearch.com to them. By doing so, it forces users to use its modified search box or the URL box, which would guarantee that the searches are performed via alternative routes or measures.

First of all, users would immediately notice that the search results are no longer being produced by Google but rather Yahoo instead. While the provider is trustworthy, it is known for its affiliate programs which are adapted by many browser hijackers and other potentially unwanted programs. Many users begin to worry when their browsers suddenly begin redirecting to Yahoo.

While the situation is not considered to be dangerous, Tail Box hijack is much more significant than one might believe. Besides the changed search provider, the app inserts plenty of ads and sponsored links at the top or other locations whenever users try to use their browsers. Without a doubt, this can greatly change which websites are being visited, which links are clicked, or even which products or services are being purchased.

It is important to note that advertising content is not always accurate, useful, or even safe, as hijackers tend to advertise other potentially unwanted programs quite often. Therefore, we recommend you avoid any sponsored links as long as the app is installed on your browser.

The unwanted data tracking

Another concerning trait of many potentially unwanted programs, Tail Box included, is data tracking practices. The main goal of such applications is not to provide some sort of useful function for users (hence many PUPs employ superficial features or fail to deliver anything useful whatsoever) but instead expose as many users to ads as possible, monetizing the process through pay-per-click[2] and similar schemes.

In order to be successful in it, potentially unwanted applications commonly track users – which websites they visit, links they click, how long they spend on certain websites, which ads they interact with, which search queries do they type, among other details. This provides the developers of PUPs to ensure that they can deliver more targeted ads to users, making them more likely to interact with them.

The side effect of this activity (even though the collected data is mostly anonymous) is that the information is regularly sold or shared with service providers, affiliate networks, and other third parties. Without a doubt, this can negatively impact users' privacy, as there are no guarantees that all the collected information isn't private and that third parties are adequately protecting it from theft or leaks.

Therefore, if you want to regain the function of your browser, you should remove the hijacker and all the other potentially unwanted applications from your system immediately. Below you will find a thorough explanation of how to do just that.

How to remove Tail Box

In most cases, potentially unwanted applications are more nuisances than a real threat, as they are accustomed to tracking anonymous user data and display ads. However, this might not always be the case, and we have seen plenty of browser extensions or programs that might seem innocent initially only to later start performing illegitimate actions, such as tracking personal data or promoting malicious ads.

Thus, even if it seems that the app is not really doing anything, it might not be the case in the background. This is precisely the reason why you should immediately, after noticing unexpected browser behavior scan your system with powerful security software, such as SpyHunter 5Combo Cleaner or Malwarebytes – this would ensure that the most aggressive PUPs and malware are deleted.

However, you should also check the section of the installed browser extensions manually, as they might not always be removed automatically. Please follow these instructions:

Google Chrome

  • Open Google Chrome, click on the Menu (three vertical dots at the top-right corner) and select More tools > Extensions.
  • In the newly opened window, you will see all the installed extensions. Uninstall all the suspicious plugins that might be related to the unwanted program by clicking Remove.Remove extensions from Chrome

Mozilla Firefox

  • Open Mozilla Firefox browser and click on the Menu (three horizontal lines at the top-right of the window).
  • Select Add-ons.
  • In here, select unwanted plugin and click Remove.Remove extensions from Firefox

MS Edge

  • Open Edge and click select Settings > Extensions.
  • Delete unwanted extensions by clicking Remove.Remove extensions from Chromium Edge

MS Edge (legacy)

  • Click on Uninstall at the bottom.Remove extensions from Edge


  • Click Safari > Preferences…
  • In the new window, pick Extensions.
  • Select the unwanted extension and select Uninstall.Remove extensions from Safari

Clean your browsers to protect your privacy

As we have previously explained, potentially unwanted applications are set to track user data for profits and the ability to show more relevant ads. These actions are performed with the help of various cache files that are placed by the hijacker as soon as it is implemented – cookies[3] are a prime example of this.

Cookies and other tracking elements are not and can't be malicious. They are small and simply do not have the capabilities or performing malicious actions on the device. Their main function is to store various preference and setting information, as well as session information – they are the primary reason why you can log in to all your accounts automatically every time you visit the same website without having to enter your credentials.

However, this feature, while useful, also poses some dangers due to a dangerous attack known as session hijacking, where cybercriminals could take over users' sessions, accessing their accounts in the process. Security experts strongly recommend learning browser caches from time to time in order to avoid this and unexpected loading errors.

To clean the web data, you would either have to access browser settings and do it manually or use an alternative method –FortectIntego scan, which can automatically remove all the leftover files from your system and fix malware-related system damage.

How to prevent from getting browser hijacker

Protect your privacy – employ a VPN

There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
