What is UC Browser?

According to its developers, UC Browser is a lightweight web browser that offers a faster browsing experience. UC Browser is developed using Chromium project, a legitimate open-source project. Despite this, other people can develop modified versions by changing the code - this is the case with UC Browser developers. Some examples of similar adware browsers are WebDiscover, Ad Expert Browser, Dash Browser, amongst many others.

UC Browser adware

Many users install UC Browser unintentionally without direct permission. Therefore, it is categorized as a potentially unwanted application (PUA). After installation, it delivers intrusive advertisements (coupons, banners, surveys, pop-ups, and so on) that are usually displayed via tools that enable placement of third party graphical content on any visited website. These ads can be very annoying and, if clicked, might redirect users to other untrustworthy sites that could also be malicious. Some of these ads might even run scripts that download and install other PUAs. The UC Browser application itself also causes redirects to uc123.com without requesting permission. Furthermore, apps such as UC Browser often collect data (IP addresses, search queries, keystrokes, URLs of visited websites, geo-locations, etc.) that might include personal details. These are shared with third parties (potentially cyber criminals) who misuse private information to generate revenue. Data tracking can cause problems relating to privacy or browsing safety, and some users might have their identities stolen. Therefore, we strongly advise that you uninstall these applications immediately.

There are many adware-type applications available, most of which share similarities: they offer users 'useful features' (enhanced browsing experience, faster and more accurate results, and so on), however, these are merely attempts to trick users into downloading and installing them. Most potentially unwanted applications do not deliver the features promised and are designed only to generate revenue for their developers and/or third parties.

How did UC Browser install on my computer?

UC Browser can be downloaded from its official website, however, it is more commonly installed stealthily without users' knowledge. Software developers often use the "bundling" method, a deceptive marketing method employed to trick users into installing potentially unwanted applications with regular software by hiding them in "Custom", "Advanced" and other similar options or settings of the installation processes. As a rule, information regarding included/bundled PUAs is not properly disclosed, and thus they often go unnoticed during the installation processes. Most apps such as UC Browser are generally installed when users skip installation steps without checking the settings and when they fail to deselect unwanted applications.

How to avoid installation of potentially unwanted applications?

Download software (especially if it is free) from official and trustworthy/reliable sources only. Avoid using third party software downloaders/installers and torrents. Check "Custom", "Advanced" and other similar settings and deselect offers to install unknown/unwanted software. Only then, finish the installation process. Be careful when browsing the internet, especially when clicking intrusive ads - many seem legitimate (developers - potentially, cyber criminals - invest time and money into their design), however, once clicked, they redirect to untrustworthy websites, such as gambling, adult dating, pornography, and so on. If you encounter these ads and redirects, check installed extensions, add-ons, and plug-ins on your browser, and programs on your computer. Uninstall all unknown/unwanted applications and programs immediately. If your computer is already infected with UC Browser, we recommend running a scan with Spyhunter for Windows to automatically eliminate this adware.
