What problems may applications like cause and how serious can they be?

System corruption, data theft, espionage and file-encryption and destruction is NOT something to be expected if you have a browser hijacker on your computer. The activities that we’ve just mentioned are actual cyber crimes typical for malicious pieces of software like Ransomware, Trojan horses or Spyware. A browser hijacker, on the other hand, is generally harmless and is generally supposed to display different sponsored ads, pop-ups, banners and page-redirect links on your screen rather than causing you harm.

Still, many users who end up with an application like on their computers start to complain about losing control over the settings of their default browser and about having their screens flooded with various aggressive and unwanted promotional messages. Most people don’t really enjoy it when their favorite browser suddenly greets them with a changed homepage or with a replaced search engine. They also tend to get panicked when the hijacked browsing app automatically starts to display some pay-per-click messages and lands them on unfamiliar web locations without their approval. This is the main reason why such software is regarded as potentially unwanted and is often uninstalled from the system without being a direct threat to the machine’s safety.

Another reason why you should generally not keep an  application like on the computer could be the rather intrusive approach which the owners of the browser hijacker usually employ in order to promote certain products, services or web pages to the users. They may oftentimes use their software as a tool that collects marketing information and generates pay-per-click revenue from positioning sponsored ads on the users’ screen. The hijacker may be set to keep track on the users’ latest searches, bookmarks, likes, shares, and browsing history and to transfer this so-called “traffic data” to third-party marketers and online advertisers, who want to promote their products and services to different targeted groups of users. This is not something illegal according to the law, but the fact that the users have no control over it and cannot stop it unless they remove the browser hijacker might be a bit bothering for some people. What is more, the traffic data monitoring may consume a fair share of the system resources for serving the marketing needs of different unfamiliar advertisers and their partners without actually providing any useful functionality to the users. Dealing with the changed settings of the browser and trying to close the never-ending stream of ads and page-redirect pop-ups could easily turn into a nuisance which most people would prefer to get rid of. Luckily, once the hijacker and all of its components have been successfully removed, the default browser settings could be restored and the users could enjoy their ads-free web surfing again.
