Mono3.biz Virus


Mono3.biz

Mono3.biz is a browser-hijacking app that targets the browsers of Windows computers and aims to promote different sites on their pages. Mono3.biz advertises the sites of its sponsors by automatically page-redirecting the browser to them during the user’s online sessions.

Mono3.biz Virus

The Mono3.biz Virus will redirect your browser.

If you have encountered this app in your browser, know that this isn’t software that will damage the system of your PC or the files and programs present on the computer’s hard-drives. Although Mono3.biz may initially seem like it is some kind of dangerous virus, it is not something to get overly worried about.

The Mono3.biz Virus

The main goal of Mono3.biz is to get installed inside popular browsers that are used by many users, such as Chrome or Firefox. Inside the browser, Mono3.biz changes the toolbar, the default omnibox search engine, and the user’s preferred homepage. The purpose of these changes is to use the modified browser elements as tools for pushing the hijacker’s advertising agenda.

The new homepage of the browser would more than likely be a site that the developers of Mono3.biz are trying to popularize. By making that site the starting page of your browser through the hijacker, they ensure that each time you start your browser, you (and every other user who has the hijacker installed on their computer) would generate more visits to the promoted site.

The search engine imposed by the hijacker is most likely a modified version of an already existing search engine service. This modified version is probably going to show more ads than usual in the search results and thereby increase the advertising revenue earned by the hijacker. None of this should be harmful to your computer (at least not directly) but these advertising activities can certainly affect the way you browse the Internet (in a negative way).

What are the potential hazards associated with browser hijackers?

Despite not being a dangerous virus program like a Trojan horse or Ransomware, Mono3.biz is definitely not something you should be keeping in your machine. The reason for that stems from the reliability (or rather the lack thereof) of the advertisements that this app would more than likely put on your screen while you are browsing. It is not advisable to trust anything advertised by a browser hijacker and the reason for that is you could never be sure about whether what’s behind a given ad or page-redirect link is what’s being advertised or if it is something entirely else (that could potentially be harmful). Unfortunately, a big portion of the sites that get promoted with the help of browser hijackers like Mono3.biz aren’t particularly safe or reliable. Some are even used for tricking users into downloading fake software or even malware, including Trojans, Spyware, viruses, and Ransomware. There are just too many ways things could go wrong if you interact with the content promoted by most hijackers, which is why it’s best if you uninstall any app that may be tampering with your browser’s settings and spamming you with ads. Detailed removal instructions for Mono3.biz you can find in the following uninstallation guide.
