The basic idea behind such an invasive monitoring practice is to collect the so-called “traffic data” from the users. This data is non-personal and is needed for an aggressive online advertising method known as Pay-Per-Click which is related to sponsored ads positioning on the screen. Assuming that ads related to the users’ recent searches would have a higher chance of getting clicked, the idea is to involve more people into clicking on the displayed popping messages. This, in turn, can generate Pay-Per-Click profits for the owners of the hijacker and can bring more traffic and exposure to the sites, products, and services, which have been promoted. There is usually nothing illegal or criminal in such practices because, as you can see, this is all solely advertising-oriented.

However, some users find it really unpleasant to have these ad-generating, data-collecting and page-redirecting processes running in the background of their systems every time they try to browse. Not to mention that, in most of the cases, neither these processes nor the installation of the hijacker and its components have been knowingly approved by the users. The software usually uses the method of “software bundling” to get installed on the system by default and typically comes along with the installer of other programs, free tools, and add-ons. Additionally, in its attempts to promote more items, the browser hijacker may take up a fair share of the system’s resources for its activities. This may contribute to a significant slowdown of the system and unresponsiveness of the affected browser. As a result, in the long run, it may really become a nuisance to surf the web which is a good reason to remove this software.
