This page aims to help you remove Uc123. Our removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.
Browser hijackers can really be the worst sometimes: the annoying ads, the constant page redirects they authorize without even asking you about it, and the changes they make to your browser settings – all of this can be extremely irritating. Not to mention that it may initially come as quite the shock, especially for users, who have no idea what they’re dealing with. One of the latest programs of this type is called Uc123 and just like other software in the browser hijacker category, it can pretty much affect any of the most popular browsers, including Chrome, Firefox, Edge and others. In addition, it will also change the homepage and set a new default search engine, which on top of that you won’t even have the opportunity to change back. The only way you will be able to do that, as well as get rid of all the intrusive popups, banners, box messages and various other online advertising materials is to remove Uc123 from your system. And doing that may prove trickier than simply uninstalling just any regular program. But with the correct set of instructions like those provided in the removal guide below, you should have no difficulties at all.
What are browser hijackers and why do they have to be so annoying?
Browser hijackers are there to advertise – nothing more, nothing less. They exist with the sole purpose of generating tons of online ads and displaying them on the users’ screens. This comes in the forms of in-text links, popups, box messages, page redirects, etc. It is their primary objective to expose you to as many products, services and websites as possible, and ideally also get you to interact with those. This, in turn, is what the browser hijacker developers make money from. They, for the most part anyway, earn revenue based on the number of ads you, the user, clicked on. That is also what primarily dictates the behavior of programs like Uc123 and is the main reason behind the incredible intrusiveness of all the constant ads. But although this may sound rather benign, browser hijackers often resort to somewhat unsavory tactics to achieve their goals and be able to squeeze out as much profit from you as possible.
For example, hijacker developers often program this type of software to be able to keep track of your online browsing habits. And given that it actually integrates with your favorite browser, it’s not too difficult for them to gain access to data related to your bookmarks, favorited websites, recent search queries, etc. This information, in fact, supplies programs like Uc123 with the necessary perspective of what your interests are. It basically tells them what type of products, services and websites you will be more likely to interact with and be attracted to. Some users actually begin to notice this and will see things like a popup or a banner that is oddly displaying the exact type of content they we looking up online the other day. That’s exactly how this works.

And if you think that’s unpleasant, there can potentially be far more serious consequences to having a browser hijackers like Uc123 installed on your PC. Now, many people make the mistake of thinking that they’ve been infected by a virus of malware of some type, when really it’s a hijacker. Luckily, that’s not that case and hijackers are not considered dangerous or harmful, the same way that Trojans or ransomware viruses are, for example. But they can, nevertheless, lead to you getting infected by something malicious of that caliber. For example, it can be as a result of the constant page redirects that you need to suffer through, which may potentially lead you to an infected web location.
