Browser hijackers – specifics and risks

Browser hijacker is a common name for a software category which consists of applications and software components that affect the way that the users’ browsers operate. A typical representative of this category is – an ad-generating browser component which tends to impose new search engine or homepage settings on the default browsing program of the user and flood their screen with various annoying ads, pop-ups and banners during each browsing session. Such software is normally set to display sponsored commercials and to redirect the web users to specific web pages or advertising content with the goal of bringing traffic and clicks as well as with the purpose of generating profits from Pay-Per-Click campaigns. This is the exact same reason why may change your browser’s settings with some sponsored domains or search engine tools and force you to use them.

Typically, this is an online marketing practice which would normally not harm your system or initiate a cyber attack. However, the presence of the hijacker and its activities may cause a lot of unwanted disturbance which is why most of the users prefer to uninstall this advertising software instead of tolerating its page redirects, ads generation and browser changes.

Tips for future safety

The main source of browser hijackers such as “Virus” and other potentially unwanted ad-generating software are usually the free download links, free software bundles and application packages which may often be found in different torrent sites, shareware platforms, freeware pages, automatic installation managers and spam. That’s why, if you stay away from these sources and do not download applications from non-reputed software developers, you may greatly reduce the risk of having your browser hijacked and getting unwanted software installed on your computer What is also very important and often neglected by many users is the way that new software should be installed on their systems. You should never rush through the setup process and make sure you always read all of the fine print, pre-selected checkboxes and the EULA of the installation package. Whenever Advanced or Custom installation options are available, it is strongly advisable to use them instead of the Quick/Automatic ones as they give detailed information and some customization options about the content of the given installer and any additionally bundled components.
