What is hijacker?

This browser hijacker is very similar to many others. New hijackers with new domain names and looks appear constantly. They pretend to be a legitimate search engine and their target is to hijack the default home page and stay there as long as possible. The generated traffic earns the adware creators revenue from search commissions, advertisements, cookie stuffing and other questionable and illegal practices. does not really offer any additional value to your browsing experience and acts only as a parasite in order to extract as much value from your generated traffic as possible. It tries to deceive the users into thinking that the website is a legitimate search engine but in reality it simply redirects to a custom Google search:

Since simultaneously queries different search providers and subsequently quickly displays 
a clear overview of the newly analyzed results obtained via a complex filter and sorting algorithm, 
using not only saves an enormous amount of time, but also enables finding high-quality websites 
and database entries that might not have been found when only performing individual, conventional Web searches.

The adware firstly appeared around May 2016 and is still active. According to Alexa rankings, currently the website has around 50 000 to 100 000 unique visits and targets many countries worldwide.

This hijacker uses the same infiltration techniques as most others: it is usually bundled with another legitimate software and is installed silently if you quickly skip through setup process. The adware hides deeply in Windows system system to make the removal process harder.

In order to avoid legal problems the website has “License”, “About”, “Privacy” and “Uninstall” sections. However, some of this information is deceptive and the removal instructions are unclear as well.
