Byluxrayor is an ad-displaying application of the browser-hijacking type that is known for targeting Windows systems. Byluxrayor enters the browser and changes the homepage address in order to start spamming you with unwanted ads and page redirects every time you go online.


Byluxrayor changes the search engine of the browser as well as its homepage address in order to ensure a maximum number of displayed ads

The purpose of this app is simple – the ads and the redirects that it shows on your screen are all connected to a Pay-Per-Click scheme that ensures each click and/or visit they receive generate a small amount of money. The goal of Byluxrayor is to make as much money as possible by popularizing different sites, products, and services on the screens of the users.

To be more effective at advertising, Byluxrayor changes the search engine of the browser as well as its homepage address in order to ensure a maximum number of displayed ads. It is irrelevant what browser you are using – Firefox, Chrome, Edge, Opera, and most other browsers could all get “infected” by a hijacker like Byluxrayor or Poshukach and get their settings altered without Admin authorization.

Signs that you have a hijacker in your browser

It is usually not difficult to tell if there’s an application like Byluxrayor in the browser. Unlike Ransomware, Spyware, or Trojan horses, the representatives of the browser hijacker family do not try to stay unnoticed by the user – quite the contrary. A hijacker would try its best to become noticed and to be as obtrusive as possible as this improves its chances of getting clicks on its ads. In some of the more extreme cases, you might even have ads, banners, and redirect links displayed in the most inconvenient of places of the webpage you are currently on. For example, if you are reading an article, the hijacker might superimpose its advert over said article and make it difficult for you to read it until you click on the advertisement. Of course, clicking on the ad would result in you getting redirected to a different site and bombarded with even more advertisements.

All of this is not only annoying but also might make your computer more vulnerable to attacks from different forms of hazardous malware. The virus threats we mentioned above – Trojans, Spyware, and Ransomware, are some of the most dangerous forms of malware that you may encounter if you tend to interact with the questionable adverts and redirects generated by Byluxrayor. The best thing you could do in order to prevent getting your PC infected is to uninstall Byluxrayor with the help of our instructions from the removal guide below.

Distribution of Byluxrayor

Most hijackers don’t get installed as separate programs. Instead, they are typically added inside file bundles, as this allows them to get distributed alongside other software. Another possibility is when they are distributed through misleading ads that claim you’d be downloading a useful program if you click on the download button. However, instead of getting an app that would benefit you in some way, you get an unwanted browser hijacker that doesn’t improve your online experience whatsoever and instead only bothers you with its endless streams of adverts.
