User ExperienceJoin Our Forum to Discuss PUP. – How Did I Get It

The primary method of replication that is used in association with this browser hijacker is believed to be conducted via what is known as software bundling. This method is the including of the program files of the hijacker to another free app that you may have added to your Mac from a third-party website. The main idea behind this is for the free apps to be spread via various different types of programs, the main ones of which are believed to be often used free apps, like media players, torrent software and several other types of applications.

In addition to this, the program may also be automatically added as a web browser extension. This can happen via JavaScript which ads it as soon as you visit a suspicious site and accept the app to be installed. Often it is pretending to be a free toolbar that is used to provide easier access to different e-mails, Facebook, news and the weather. – More Info

The browser hijacker, displays a search engine, which when used redirects you via a new tab to results from, that are cramped up with advertisements to third-party websites.

These types of clicks leading to third-party search sites also contribute to the main version that the browser hijacker does not have it’s own search engine, which is typical for hoax search engines. Furthermore, the browser hijacker is also the type of software aimed at creating multiple different types of cookies and other tracking technologies on your Mac as we have detected:

These tracking technologies all aim to obtain the following types of information from your web browser:

  • Browsing history.
  • Search history.
  • Online clicks information.
  • Data on the websites you have bookmarked.
  • The ads you have clicked on.

This information is often used to display different types of advertisements. These ads may not only slow down your Mac, but also represent couple of risks to It, such as they may lead you to scam sites and they may even lead you to malicious sites, that may infect your Mac with malware. They are different types:

  • Browser redirects.
  • Pop-ups.
  • Online search results.
  • Banners.
  • Highlighted text ads.

Besides the unusually high amount of advertising, the hijacker may also perform other unwanted activities on the victim machine, such as to display multiple pop-ups that it wants the user to allow push notification. This may further contribute the process of showing third-party ads on your Mac:
