How to eliminate browser redirects to uc123.com?

What is uc123.com?

Uc123.com is one of the many fake search engines that is promoted as legitimate search engine which supposedly provides users with enhanced browser experience, more accurate search results and allows users to access various other websites directly from the search engine. For some, it might look like a legitimate search engine, however, it is being promoted by application, a browser hijacker called UC Browser (also known as UC web accelerator). Both uc123.com and the UC Browser browser hijacker are designed to gather various data that is related to user's browsing habits/activity.

uc123.com browser hijacker

This browser hijacker and its fake search engine targets the most popular web browsers such as Internet Explorer, Google Chrome and Mozilla Firefox. Once a web browser is affected, default search engine, homepage and URLs of new tabs get changed to uc123.com. Besides, the UC Browser browser hijacker appends the uc123.com URL to the target of affected web browser's shortcut. All this means that users are forced to visit uc123.com either they open a new tab in a web browser or the web browser itself. What's more, users cannot undo these changes, at least not the usual way, and that is because it is very common for "helper objects" to be installed together with browser hijackers. These applications are designed to prevent users from undoing the changes made by reverting them as soon as users try to modify them. Another downside of having a browser hijacker and helper objects installed is that these apps usually are designed to gather data such as IP addresses, keystrokes, search queries, URLs of visited websites and various other information that might contain personal or sensitive data too. Later this data is shared with third parties (potentially cyber criminals) who misuse it to generate revenue. Such actions might cause users various privacy or browsing safety issues, some users might even have their identities stolen. If you experiencing any of the mentioned symptoms, we strongly advise you to remove all suspicious/unknown applications from your web browser as soon as possible and to do not ever visit uc123.com again.

The Internet is full of fake search engines (like search.searchttab.com, go.querymo.com, search.gg and many more) that are promoted as useful search engines because of supposedly improved search results and so on, however, these are only attempts of their developers to give an impression of legitimacy. Most of the times such fake search engines are designed only to generate revenue for their developers and/or third parties, and usually there is not use in them for any regular users, since most of them only cause unwanted redirects and collect data.

How did uc123.com install on my computer?

Like many others, uc123.com is promote using rogue download or installation set-ups, in other words - using a deceptive marketing method called "bundling". Bundling is a method used to trick users into installing or downloading various PUAs without their knowledge. Various browser hijackers or other potentially unwanted applications usually are hidden in "Custom", "Advanced" and other similar settings of the installation processes. Software developers do not disclose information about bundled apps properly and that is how many users install them without noticing them being present or when simply skipping the installation steps without checking any of the mentioned settings. As a result, users often expose their systems to risks of various infections or pose a direct threat to their own online privacy.

How to avoid installation of potentially unwanted applications?

To avoid having any potentially unwanted applications installed always download and install software with care. Do not download software from unofficial/untrustworthy websites, using torrent clients or some third party installers, or downloaders. It is strongly recommended to use only official sources and direct links for that. Besides, never rush any installation process - check what are "Custom", "Advanced" settings and deselect ay potentially unwanted apps. Keep in mind that most intrusive ads are designed to look appropriate and legitimate, their developers (potentially cyber criminals) invest resources in their design. However, there are ads that redirect to various untrustworthy websites like gambling, pornography, adult dating and so on. Very often these advertisements are delivered by adware-type applications. If you encounter redirects to untrustworthy or suspicious websites, make sure that there are no unwanted/unknown applications (such as plug-ins, extensions or add-ons) installed on your web browser and uninstall them immediately. Same applies to the programs intalled 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.
