Behind the url address uc123.com, there’s a Chinese browser hijacker lurking in the back. A browser hijacker is a program that installs a website (uc123.com in this case) as default homepage and default search engine without asking for any kind of approval beforehand. This kind of parasite is developed for 3 main reasons.
The first one is to increase web traffic, usually this kind of parasite affects tens of thousands of users by means of malvertising campaigns. Every time an affected user opens his/her web browser, this alleged search engine is shown which counts as yet another visit. Thanks to this web traffic, ratings for uc123.com will increase in the face of websites like Google, which is exactly what they need.
Reason number two is related to advertising. uc123.com is filled with ads. uc123.com’s developers earn money every time one of this ads is seen or followed through by means of a click. They go as far as posing ads as legitimate results in the results page.
Last but not least, they are after data recollection. When uc123.com is installed, the install program has access (and might still have it) to everything you do and have on your computer. Therefore your data is no longer protected.
To solve all of these issues, you must as soon as possible remove uc123.com. Our guide will explain how to do that for free!
