Remove Tail Box Hijacker
Tail Box is an intrusive browser add-on, which might be installed alongside other software because of software bundling. Thankfully, Tail Box is not malicious at all. However, we do consider it to be a Potentially Unwanted Program (PUP) that could cause some undesired changes to the configuration of Web browsers. Tail Box appears to affect Google Chrome, Mozilla Firefox, and other browsers based on these two projects.
The Tail Box hijacker promotes the search service Tialsearch.com by setting it as the default new tab page and search engine that your browser uses. The Tail Box hijacker's website is not malicious, but using it on a daily basis might not be a good idea. Tailsearch.com could prioritize showing sponsorted results, ads, and other marketing content. This will greatly diminish the quality of your online searches.
If you spot Tail Box or Tailsearch.com on your device, you should consider removing them immediately. Unfortunately, trying to fix your browser settings will not work, because Tail Box will reapply the changes. Instead, you should use an up-to-date security tool to eradicate the Tail Box hijacker fully. Once you do this, you should be able to fix your settings easily.
