This page aims to help you remove Ucarecdn “Virus”. Our removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.

Have you lately experienced an annoying browser redirecting activity on your Chrome, Firefox or Internet Explorer browser? If yes, you should know that this activity is typically caused by software applications known as browser hijackers. The browser hijackers are not dangerous programs but they could certainly be very annoying. On this page, we are going to tell you more about one particular representative of the hijacker class called Ucarecdn “Virus”, which could be the most probable source of your recent browsing redirects and disturbance. The possible unwanted effects of this hijacker could include sudden changes in your browser’s homepage or search engine, installation of a new toolbar, generation of various intrusive ads on your screen as well as redirection to different sites, new tabs, links and other web locations. If you stay with us, you will learn how to remove all these changes and uninstall Ucarecdn “Virus” without risk for your system, as well as how to return your browser settings back to normal and prevent future hijacking.

What is Ucarecdn “Virus”?

Browser hijackers, in general, are not a threat to your PC. Landing such piece of software on your system might be really annoying, frustrating and unpleasant but fortunately nothing fatal or destructive should come from such software. An application like Ucarecdn “Virus” isn’t likely to cause any damage to your files or to your software and unlike a real virus (such as a Ransomware, a Trojan horse, a Spyware, a Worm, etc.) it likely has no malicious code in it. Typically, once inside your computer, the browser hijacker may replace your default homepage or search engine and install a new one or set a redirecting service, which might land you on various ads, pop-ups, banners and new tabs every time you open a new browsing session. Typically, none of the changes introduced by the hijacker are actually approved by the user. You may also have a hard time reverting the said changes and removing their source because the hijacker may reappear again and again if not removed properly from your system. All in all, dealing with Ucarecdn may bring you a lot of irritation yet, apart from that, no damage would normally be caused to your system.

Why does such software get created?

If they are not computer viruses but are still considered unwanted, why do hijackers get created in the first place? Well, the answer is for advertising purposes. The online marketers along with the software developers create programs like Ucarecdn and use them to advertise certain products, software, services, websites, search engines and sales pages directly on the users’ screen by hijacking their browser. Not so long ago, the most popular method of advertising was the TV ads but nowadays, since more and more people start spending a lot of time online, browsing the Internet, web browsers have become the perfect place to display ads. Tools such as Ucarecdn help the advertisers generate their ads, redirect the users to certain pages that need to be promoted and make them click on (and eventually buy) the items that are advertised. Typically, there is cooperation between the developers of browser hijackers and the people who want to have their products advertised as the first ones agree to generate ads for certain products and display them to users as much as possible, while the second group usually pays for the advertising service on a Pay-Per-Click basis. Such business model is very common in the online marketing circles and does not typically break any laws.

How may Ucarecdn “Virus” become part of your system?

There are many ways in which a browser hijacker may become part of your system. These programs are widely distributed over the Internet and could be found on many different web locations. Fortunately, they cannot infect you secretly the way that threats such as Ransomware or Trojans usually do. Some browser hijackers have their own websites from where they can be downloaded. Oftentimes, these tools are promoted as useful software for enhancing the browsing experience or providing some interesting feature to the users. That’s why, in many cases, people might actually download and install them on their own. Browser hijackers/browser page-redirects like Ucarecdn could also be found in freeware or shareware sites, torrent platforms, spam messages, email attachments, and free download links. However, most commonly, they are bundled with the installer of another program which is typically distributed for free. Different games, new applications, free software, converters, audio or video players and other attractive programs may contain ad-generating pieces of software inside their installation pack. That’s why, if you intend to install such bundles, we advise you to carefully read the EULA and check for any pre-selected or additional components before proceeding with the installation process. This could easily be done if you click on the Advanced/Manual/Custom installation settings and carefully check for any potentially unwanted software added there.
