What is a Browser hijacker and how dangerous could it be?

Applications which are known for their ability to display various ads on the users’ screen or imposing certain changes on their browser (e.g. change in the homepage, replacement of the search engine or of the toolbar, automatic page-redirects, etc.) are usually classified as Browser hijackers. These applications operate in a specific way and are normally considered to be potentially unwanted. Mactonic is an application of this type and our “How to remove” team has received a number of reports regarding it. This browser hijacker has been released just recently and according to the reports, it has managed to cause disturbance to a lot of users with its ad-generation, browser changes, and page-redirects. That’s why, here we are going to show you how to remove it from your PC in such a way that it will never disturb your browsing again.

If you are wondering how such an irritating and annoying app like Mactonic can get installed on your PC without your knowledge and what its actual purpose is, here we have some interesting information for you. Most of the Browser hijackers and similar ad-generating programs are usually created to serve the needs of the online marketing industry. These programs display sponsored commercials, homepages, websites and pop-ups or install search engines and toolbars of partners in exchange for small commissions or paid clicks. This way, they generate revenue for their developers and, at the same time, advertise and promote certain offers, deals, products, services or software directly on the users’ screen. Both, the people who need to have their products advertised and the developers of hijacker apps can benefit from such an activity. The former gain more exposure and potential buyers, while the latter can make money from paid clicks and thus “sponsor” their software or make it available for free.

Basically, the most common way the users end up with a piece of software like Mactonic on their system is when they install some free software bundle or an update, without paying the necessary attention to the Advanced setup settings. Another way to end up with a Browser hijacker is via spam emails, free download links, automatic installation managers, open source and freeware platforms or torrents. The golden rule to help you keep away from such potentially unwanted software is to always pay attention to the setup of every new programs and to be mindful your download sources.

Is there any danger if a hijacker like Mactonic operates on your system?

Luckily, the Browser hijackers are not the same as computer viruses and, therefore, they cannot normally harm your PC in any serious way. Still, due to their intrusiveness and irritating ad-generating and page-redirecting activities, such programs are often regarded as some sort of annoying malware and even may be thought of as computer threats as nasty as Ransomware or Trojans. However, this is a common misconception because applications such as Mactonic are very unlikely to initiate some action of corruption, destruction or theft while on your machine. In fact, if you stay away from the sketchy content and avoid clicking on the various shady and aggressive ads, you have nothing to worry about.

Still, bear in mind that a hijacker like this one can always redirect you to unfamiliar web-pages or links with irrelevant or questionable content. That’s why, if you want to avoid any potential encounters with security hazards the likes of Spyware, Ransomware or Trojan Horse viruses, it is advisable to have Mactonic uninstalled and all of its ads and browser components removed from your system.
