Uiz.io

Uiz.io is a browser hijacker application that can fill your monitor with ads and redirect you to unfamiliar websites. Uiz.io may also replace the default browser’s search engine, its homepage, or the new tab page.

Uiz.io

The Uiz.io Virus will try to install a Trojan Horse on your computer.

To your relief, such programs are not as dangerous as Ransomware, Spyware, and other viruses but, sometimes, the browser hijackers can be really irritating. The constant page redirects they can initiate without even asking you for approval and the changes they make to your browser’s settings can be very frustrating, especially for users who don’t know what they’re dealing with. Not to mention that the ads, the banners, and the nagging pop-ups that get placed on literally every webpage you visit may not always be safe.

Browser hijackers like Uiz.io can normally affect almost any of the most popular browsers, including Chrome, Firefox, Edge, Safari, and others and replace their homepage, set a new search engine, change the new tab page or install some additional toolbars.

Fortunately, in our removal guide, we will assist you to bring your browser’s settings back to normal by uninstalling Uiz.io and its imposed modifications in a quick and reliable manner. Don’t worry if you are not experienced with removing such apps because below you will find all the information and instructions that you will need.

Why do programs like Uiz.io exist?

The browser hijackers are pieces of software that advertise different websites and their products and services. Such programs exist for the sole purpose of generating and displaying loads of pop-ups, banners, colorful ads, redirect links, and promotional messages on the screens of the web users in order to get clicks on these ads. The developers of browser hijackers earn revenue for what their software is doing based on the number of ads clicked. That’s basically what dictates the behavior of programs like Uiz.io and explains the browser changes and the constant ads streaming that is happening on your screen. Sadly, in many cases, the browser hijackers resort to somewhat aggressive online advertising tactics to accomplish their goals and to be able to generate as much pay-per-click profit as possible.

Most commonly, programs of this kind can keep track of the user’s browsing habits online. And since they actually integrate with the main browser, programs like Uiz.io can easily access data related to the user’s bookmarks, recently visited websites, recent search queries, etc. The collected information provides the hijacker with an insight into what the user’s interests are at the moment. This tells the program what kind of advertisements to display so that the user is more likely to click on them. This is not as bad as having your files encrypted by a Ransomware or your passwords stolen by a Trojan-based virus but to most people it is a form of privacy invasion and a rather unwanted activity. Besides, keeping a browser hijacker such as Uiz.io on your system could create additional browsing disturbance in the long run. For example, the hijacked browser may start to freeze, become unresponsive, or experience frequent crashes. Moreover, the constant page redirects to random sites may potentially lead you to an infected page or get you exposed to compromised ads that could deliver real viruses to your system. However, there is no need to wait to catch a virus or experience all this browsing disturbance to remove Uiz.io. Just use the guide below and uninstall the unwanted program at once.

WARNING! READ CAREFULLY BEFORE PROCEEDING!

We get asked this a lot, so we are putting it here: Removing parasite manually may take hours and damage your system in the process. We recommend downloading SpyHunter to see if it can detect parasite files for you.

Press CTRL + SHIFT + ESC at the same time and go to the Processes Tab (the “Details” Tab on Win 8 and 10). Try to determine which processes are dangerous.

Right click on each of them and select Open File Location. Then scan the files with our free online virus scanner:

After you open their folder, end the processes that are infected, then delete their folders. 

Note: If you are sure something is part of the infection – delete it, even if the scanner doesn’t flag it. No anti-virus program can detect all infections. 

Step3

Hold together the Start Key and R. Type appwiz.cpl –> OK.

To remove parasite on your own, you may have to meddle with system files and registries. If you were to do this, you need to be extremely careful, because you may damage your system.

If you want to avoid the risk, we recommend downloading SpyHunter
a professional malware removal tool.
