removal by Gabriel E. Hall - - | Type: Browser Hijackers is a browser hijacker that modifies web browser settings in order to show users fake search results

Questions about virus is a browser-hijacking application developed by Kinner Lake Limited – a Gibraltar-based company. The unwanted programs usually enter machines without users noticing, as software bundles typically try to hide optional installs under Advanced settings, and most people simply skip this step by choosing the Recommended mode. Once inside the machine, virus starts performing a variety of changes, including the ones that modify users' homepage and a new tab, along with the search engine. From that point, users are forced to browse via the hijacked engine,[1] which typically shows them fake search results that include a colossal amount of sponsored links, deal with redirects to questionable websites, and suffer from the slow operation of the browser.

While browser hijackers are not considered to be severe computer infections, their presence might compromise computer security and users' online safety. In this article, we will explain peculiarities of this type of threat, and will also describe how to remove from Google Chrome, Mozilla Firefox, Safari, Opera, or another browser.

The primary goal of Under Cover Search developers is to generate traffic to sponsored websites, which would consequently increase the profits for both parties. For that, PUP authors need to make sure that hijacker reaches as many users as possible – hence the shady distribution technique.

Once the changes to the installed browsers are made, starts its shady activities by displaying sponsored content, placing a layer of ads on most sites, exposing to altered search results, and also tracking users' web browsing activities. This is done with the help of tracking technologies, such as Beacons[2] or Cookies. This information-gathering allows developers to gather the following information:[3]

  • technical information transmitted by your device such as type of operating system, device type, default browser;
  • your aggregated use of the Software, basically we know if you installed the software;
  • usage statistics;
  • language and the time stamp;
  • approximate geographical location.

This data is collected in order to generate personalized ads, but these are always coming from the affiliates. Therefore, hijack can manipulate what sites users visit, influence their interests and make them buy products or services that they otherwise would not.

Therefore, while the browser hijacking changes might seem relatively minor, it might result in the installation of potentially dangerous apps, exposure to online scams, and even malware infection. Thus, if you noticed that your homepage has changed, check your system with security software or perform manual removal as explained below. After you kill the PUP, make sure you use Reimage or similar repair software to bring your device to a pristine condition. hijacker is a browser hijacker that modifies web browser settings without permission in order to perform the revenue-generating activities

Make use of Advanced installation settings to avoid PUPs

If you do not want to let potentially unwanted programs hijack your computer, you should pay more attention to the software installation process. Contrary to many people’s beliefs, Default or Recommended installation settings are not the ones that should be trusted during the procedure.

In fact, Custom or Advanced settings will allow you to determine which applications are secretly offered to you. Therefore, opt for these settings because they enable you to reject unwanted items added to the desired software. Be aware that most of the free apps will include some sort of “offer” or “deal,” and it might be hidden in various ways, including grayed out buttons, pre-ticked boxes, misleading placement of the toggle, etc.

There are two ways to terminate from your computer
