Search(.)Xfinity(.)com Browser Hijacker – How Does It Replicate

In order to be installed on the computers of unsuspecting users who do not need it, the Search(.)Xfinity(.)com browser hijacker takes different shapes:

  • A Xfinity tv toolbar.
  • Constant Guard toolbar.
  • Xfinity Connect add-on.

These browser extensions may be added unwillingly via free programs downloaded from the web. One of those free programs may be your favorite torrent downloading software, media player or other useful freeware. If downloaded from third-party websites that provide a lot of software in one place, these installers may contain Search(.)Xfinity(.)com browser hijacker added in the form of such toolbars. It can be encountered somewhere along the installation process, for example:

  • “Add Constant Guard Toolbar as a helpful tool to protect you online.”
  • “Add Xfinity tv to help with your online multimedia experience.”

Users are strongly advised to opt-out of such additional applications while installing free software downloaded from third-party sites. The best method to find them is always to check the EULA agreement of the software they are installing and always choose the “Advanced” or “Custom” installation options.

Furthermore, the search engine does not have HTTP’s encryption which presents a hypothetical threat to the user, since it allows not only the injection of scripts by third-party sites but also the usage of tracking software. It can be used to display targeted content and infect the computer with malware in a targeted attack.
