If Browser Hijacker doesn’t ring a bell

Browser Hijacker is derived from the term “advertisement software”. Apparently, this software represents the programs that generate probably unwanted ads in various forms (pop-ups/banners/pop-unders/newly-opened browser tabs and windows).

Nonetheless, Browser Hijackers are criticized because they may use quite intrusive in the way they disturb your browsing process and at times rather shady methods of distribution. However, please, don’t get panicked! Browser Hijacker is not similar to malware because it cannot self-replicate, compromise private data or take control of the computer system. What’s more, you can be sure that Browser Hijacker-like programs will not demand money as ransomware typically does. They just need your attention and time because they are paid to promote services and products.

Many of the Browser Hijacker-developing and distributing companies are absolutely legal. In most of the cases this ad-producing software might just seem extremely disturbing. However, some of the Browser Hijacker programmers could be indeed less scrupulous and could be likely to program their Browser Hijacker-based products to track your browsing habits search requests online. This is how this type of software is able to show mainly advertisements related to your recent searches and personal tastes. Another possible threat that may come from Browser Hijacker is that the generated pop-ups and banners could redirect you to webpages with probably dangerous content like, for example – Ransomware.
Another possible way a user may get  infected with Browser Hijacker is by visiting an already infected page in the web.  One more option of catching such irritating software is by using a torrent website that is not trustworthy.

Be cautious because Browser Hijacker is able to integrate itself into all the most famous browsers (Firefox, Chrome, Opera and Internet Explorer).
