How to eliminate browser redirects to uc123.com?
What is uc123.com?
Uc123.com is one of many fake search engines that is promoted as legitimate search engine and supposedly provides users with an enhanced browsing experience, more accurate search results, and allows access to other sites directly from the search engine. This may seem to be a legitimate search engine, however, it is promoted by a browser hijacker called UC Browser (also known as UC web accelerator). Both uc123.com and the UC Browser browser hijacker gather data relating to users' browsing habits/activity.
This browser hijacker and its associated fake search engine target the most popular browsers (Internet Explorer, Google Chrome, and Mozilla Firefox). Once a web browser is affected, the default search engine, homepage, and new tab URL settings are changed to uc123.com. Furthermore, the UC Browser browser hijacker appends the uc123.com URL to the target of affected web browser shortcuts. Therefore, users are forced to visit uc123.com when they open a new tab within a browser, or open the browser itself. Users cannot undo these changes, at least not the usual way, is since "helper objects" are often installed with browser hijackers. These applications prevent users from reverting the changes made (they are changed back when users try to modify them). In addition, these apps usually gather data such as IP addresses, keystrokes, search queries, URLs of visited websites and various other information that might contain personal or sensitive details. This information is shared with third parties (potentially cyber criminals) who misuse it to generate revenue. These actions can lead to privacy or browsing safety issues, and some users might even have their identities stolen. If you experience any of these problems, we strongly advise you to remove all suspicious/unknown applications from your browser immediately and do not visit uc123.com.

The internet is full of fake search engines (such as search.searchttab.com, go.querymo.com, search.gg, etc,) that are promoted as 'useful', supposedly due to improved search results and so on. These are merely attempts by developers to give the impression of legitimacy. Fake search engines are designed only to generate revenue for their developers and third parties. They provide no real value for regular users, since most only cause unwanted redirects and collect data.
How did uc123.com install on my computer?
As with many other dubious sites, uc123.com is promoted using rogue download or installation set-ups (i.e., using a deceptive marketing method called "bundling"). Bundling is used to trick users into installing or downloading PUAs without their knowledge. Various browser hijackers or other potentially unwanted applications are usually hidden in "Custom", "Advanced" and other similar settings of the installation processes. Software developers do not disclose information about bundled apps properly, and thus many users install them without noticing their presence or because they skip installation steps without checking. This exposes their systems to risks of various infections and poses a direct threat to their online privacy.
How to avoid installation of potentially unwanted applications?
To avoid installation of potentially unwanted applications, download and install software with care. Do not download software from unofficial/untrustworthy websites, using torrent clients, or third party installers/downloaders. You are strongly advised to use official sources and direct links only. Never rush the installation process - check "Custom", "Advanced" settings and deselect any potentially unwanted apps. Bear in mind that most intrusive ads seem legitimate, since developers (potentially, cyber criminals) invest resources into their design, however, some redirect to untrustworthy websites such as gambling, pornography, adult dating, and so on. These advertisements are delivered by adware-type applications. If you encounter redirects to untrustworthy or suspicious websites, check for unwanted/unknown applications (plug-ins, extensions, and add-ons) installed on your browser and uninstall them immediately. The same applies to the programs installed on your operating system. If your computer is already infected with browser hijackers, we recommend running a scan with Spyhunter for Windows to automatically eliminate it.
