Chromnius is an unwelcome browser hijacking app that gets attached to browsers like Chrome, Edge, Firefox and others, and forces the users to go to unknown sites. Chromnius also displays pay-per-click ads, and different sponsored banners and pop-ups during the web browsing sessions in an attempt to generate revenue for its developers.
Nowadays, even if you have the strongest ad-blocker installed on your web browser, it is very difficult, if not impossible, to stop seeing different nagging advertisements in your browsing window. Seeing advertisements from the pages that you visit and dealing with pop-ups and banner ads that have been powered by a program like Chromnius, however, is a completely different thing.
The Chromnius Virus
Unlike the websites who have in-built ads that can be blocked or managed, the Chromnius virus is a piece of software that has been specifically developed to display hundreds of random sponsored commercials on every web page that you visit. The Chromnius virus is also known to initiate auto redirects to specific websites and to make unauthorized changes to the browser’s search engine and homepage settings.
An ad-blocker would be utterly useless against the intrusive advertising materials that Chromnius will actively push during your web surfing and your attempts to uninstall the newly imposed browser changes are also likely to be ineffective. The homepage, search engines and toolbar updates in the browser, however, are typical symptoms that you are dealing with a browser hijacker representative.
The adjustments that browser hijackers like Chromnius, Main Captcha Top, Me.fo, tend to make are often seen as potentially unwanted firstly because they usually aren’t directly approved by the users and secondly because the only purpose of these improvements is to further increase the amount and intrusiveness of all the invasive adverts, which constantly prompt you to purchase something, visit a specific URL, download some other software, or register for some dubious online service.
What do you do if your browser has been hijacked?
In general, it is not an extremely major trouble to get an app like Chromnius in your browser. The activities of most browser hijackers cannot be compared to getting your computer locked by a Ransomware virus or becoming a victim of a Trojan Horse attack. It is, nevertheless, necessary to do the right thing and remove the invasive page-redirecting and ad-generating tool before it really creates some problems.
Browser hijackers are programmed to get you to click on different sponsored ads that link to websites they promote because this is how they generate revenue from their ad-displaying and page-redirecting activity. However, the reliability of the displayed links and promotional messages is not guaranteed and if you click on one of the ads that an app like Chromnius displays, you might end up on a sketchy or potentially dangerous website that may contain viruses, Trojans, Ransomware and other malware
That’s why the best solution is to permanently remove the ads and uninstall the hijacker from your system. This will render your browser safe and stable again and will reduce the chances of landing on a questionable web location thanks to random redirects.
