A strange new application named “Virus”, may cause a lot of disturbance to your normal web browsing if it becomes part of your Chrome, Firefox or Safari browser. This application operates as a browser hijacker and, therefore, it has the ability to change your Internet settings, install some new homepage, toolbar or search engine to the browser and initiate automatic page-redirects without your approval.

Its presence on the system is not fatal but this app may start to flood the people’s screens with various aggressive ads, pop-ups, and banners as well as prompt them to click on certain pay-per-click links and sponsored web pages. For this reason, the browser hijacker is usually considered to be potentially unwanted and many web users are seeking effective methods to uninstall it and remove its imposed changes.

The tips that we have listed below are equally valid not only for protecting your machine from potentially unwanted applications but also from much more sinister computer threats such as Ransomware viruses, Trojans, Worms, Spyware, etc. For this reason, we highly recommend that you carefully read the next tips and try to apply them in the future.

What is the main goal of applications like

Software pieces such as are not among the most harmful types of software you may encounter. These browser hijackers are oftentimes used as aggressive online advertising tools which are used as a pay-per-click remuneration tools. They are created to promote certain homepage domains, toolbars, search engines and different sponsored websites, ads, pop-ups and banners on the users’ screens during their normal web surfing. Basically, every click on a given ad generates income for the developers of the hijacker. That’s why, this software is programmed to advertise very aggressively. It typically hijacks the default browser by imposing some changes on it which might not have been directly approved by the users but would serve the advertising goal of the developers. It is sometimes debatable  how useful such a type of software is for the people who have it on their computers. In some of the cases, the hijacker might indeed offer some relevant services or solutions which the users’ might be interested in. However, to support its services and still remain free for use, the annoying software might analyze the recent web searches, browsing history, bookmarks and likes of the user and may send this “traffic data” back to its developers or third-party marketers. In addition, the hijacker may exploit a fair share of the system’s resources for its ad-generating activity and may contribute to system lags, sluggishness, browser unresponsiveness, sudden crashes and freezing of the screen. This, in turn, may prevent the users from browsing the web in peace and using their computers normally. Therefore, in most of the cases, the presence of applications like is considered to be annoying and disturbing. Another reason for which many users prefer to have these applications uninstalled and all of their ads removed is the fear of clicking on some fake or misleading ads, links, phishing websites or other potentially dangerous content. Bumping into virus transmitters is certainly not guaranteed to happen and making you do that is certainly not the goal of the browser hijackers. However, such risks still exist because the cybercriminals are getting more and more creative in their attempts of spreading Ransomware, Spyware, Trojans and similar sneaky threats and they may find a way to insert a nasty virus in the stream of random ads on the users’ screen when there’s a hijacker in the PC. That’s why, it is a good idea to stay away from any unfamiliar links, pop-ups, new toolbars and fishy offers that might appear on your monitor because you can never be sure where they may be coming from.
