If you are experiencing issues with your browser where the browser has started to flood your screen with obnoxious and highly invasive advertisements, page-redirects, banners and other irritating content, then you should consider the possibility of having a browser hijacker inside of it. Browser hijackers are pieces of software that usually resemble extensions for different browsers – Chrome, Edge, Firefox, sometimes even Safari. The idea is that once the hijacker gets installed on the computer and added to its default browser, it would make changes to the browsing program effectively turning it into an ad-broadcasting platform. Changes may be imposed on the search engine of the browser, to its starting page address and the address of its new-tab page as well as to the toolbar. Again, the idea behind all the potential modifications is to make the stream of ads more consistent and effective. Needless to say, all of this is done for money – after all, the online advertising industry is huge and the profits can get quite sizeable as long as enough users get exposed to the ads.

Remember not to touch any of the ads!

This may sound a bit excessive, after all, these are just online ads and actually some of them may be interesting to you, but you need to understand that not everything may be as it seems.

Well, what is to say that some of the ads shown to you by the hijacker aren’t going to land you on such web locations if you click on them. Understandably, it is better to not risk your computer’s safety by randomly clicking on questionable online content. This again brings us to the importance of eliminating the unwanted app – this will put an end to the ads and allow you to bring your browser’s settings back to normal.
