What is UC Browser?

UC Browser is a web browser that, according to its developers, is a lightweight web browser which basically offers users a faster browsing experience. UC Browser is developed using a Chromium project which itself is a legitimate open-source project. However, other people can develop their own modified versions and change its code, like UC Browser developers did. Some examples of similar adware browsers are WebDiscover, Ad Expert Browser, Dash Browser and many others.

UC Browser adware

Quite often users install UC Browser unintentionally, it usually gets installed without a direct users permission and that is why it is categorized as potentially unwanted application (PUA). Once installed, it starts do deliver various intrusive advertisements (such as coupons, banners, surveys, pop-ups and so on) that usually are displayed using tools that enable placement of third party graphical content on any visited website. Such appearing ads can be very annoying, and, if clicked, they might redirect users to various untrustworthy websites that could be malicious. Some of these ads might even run scripts that are designed to download and install other PUAs. UC Browser application itself also causes redirects to uc123.com, without asking any permission for that. Moreover, apps like UC Browser often are designed to collect various data (IP addresses, search queries, keystrokes, URLs of visited websites, geo-locations etc.) that might consist of some sensitive or personal information as well. It is very likely that collected data will be shared with third parties (potentially cyber criminals) who misuse it to generate revenue. Actions like data tracking might cause users not only problems related to privacy or browsing safety, but some users might end up having their identities stolen as well. These are the main reasons why it is strongly recommended to uninstall such applications immediately.

There are many adware-type applications out there and most of them share the same similarities: these apps offer users some useful features (like enhanced browsing experience, faster and more accurate results and so on), however, most of the times these are only attempts to trick users into downloading and installing them. Most of such potentially unwanted applications do not deliver the promised features 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 likely that it got installed in a stealthy way/without your knowledge. Very often software developers use a "bundling" method, a deceptive marketing method that is used to trick users into installing various potentially unwanted applications within some regular software by hiding them in "Custom", "Advanced" and other similar options or settings of the installation processes. As a rule, information about the included/bundled PUAs is not disclosed properly and that is why it is harder to notice them during the installation processes. Most often apps like UC Browser get installed when users skip the installation steps without checking the mentioned settings and deselecting unwanted applications.

How to avoid installation of potentially unwanted applications?

Always download software (especially if it is free) from official and trustworthy/reliable sources. Avoid using third party software downloaders or installers and torrents. Always check what are the "Custom", "Advanced" and other similar settings and deselect offers to install some unknown/unwanted software. Once you are done with it, you can finish the installation process. Be careful when browsing the Internet, especially when it comes to clicking intrusive ads. There are many intrusive ads that look legitimate (their developers, potentially, cyber criminals invest money in their design). However, once clicked, they redirect users to various untrustworthy websites, such as gambling, adult dating, pornography and so on. If you encounter such ads and redirects, check what are the installed extensions, add-ons or plug-ins on your web browser and programs on your computer, and uninstall all unknown/unwanted applications or programs as soon as possible. If your computer is already infected with UC Browser, we recommend running a scan with Spyhunter for Windows to automatically eliminate this adware.
