What do we know about Uc123.com virus?

Uc123.com virus is a malware which belongs to the Hao123 malware family which has come to light in 2016. This particular group of viruses is famous for taking over the control of the web browsers and making people use predetermined search engines instead of their regular ones. In the case of the Uc123 hijack, the first thing that the virus does when it infects computers is replace the default search engine and homepage of all the web browsers it finds installed on the system with Uc123.com. This domain is a news site that doubles as a search engine. The main defining characteristic of this site is that all the information on it is presented in Chinese. So, every search attempt on this site will lead you to mostly Chinese search results. Besides, the virus will also try to send you to various websites promoting Chinese goods and services or display random ads even when you are not on the Uc123 domain at all. Not the most handy functionality if you live outside the People’s Republic of China, isn’t it? If you have been infected with this hijacker against your knowledge, do not hesitate to remove Uc123.com from your computer. We kindly suggest executing the elimination safely and employing reputable antivirus software to help through the process. If you haven’t got such a utility installed already, we recommend obtaining ReimageIntego and running a thorough system scan with it.

Uc123.com virus

As we have already mentioned, Hao123-related viruses are not country-bound; thus, they can easily spread to whatever part of the world that can be found in the global network map. Besides, the site is quite useless even to the native speakers: its search results are mostly filled with ads while the homepage displays deceptive links and images that are mainly clickbait material. After investigating the site closer, we have also found that every search query entered on this site leads to baidu.com — another site related to Hao123. So, it is obvious that the hijacker is completely intertwined with Hao123, therefore is unsafe to use as a web search engine. And that’s not even all of the issues you will have to face when the virus hits your computer. Most of the problems hide underneath the surface. The hijacker has data tracking abilities and may collect information about your visited websites, searched items and system specifications. Most importantly, there are no guarantees that some of your more sensitive information such as the email address, name or home address will not slip through as well. This data can later be used to generate targeted ads, send spam emails or deliver other malware on your computer.

About browser hijacker distribution

Are you an active computer user? Do you spend a lot of time on the web and frequently download freeware? If so, you may already consider yourself enrolled in the list of the potential Uc123.com hijack victims. Be especially aware of how you install new programs. If you skip through the installation without closely analyzing the full software package components, you are more likely to allow malware to enter your computer unknowingly. Instead of carelessly pressing the “Next” button, choose the Advanced mode and follow the preceding steps of the installation to find potentially unwanted components and opt them out. For instance, when you see an option allowing to make Uc123.com your default search engine, untick the checkbox next to it and continue with the installation confident that you will find no surprises on your PC after you are done.

Uc123.com removal guidelines:

How to prevent from getting browser hijackers

Securely connect to your website wherever you are

Sometimes you may need to log in to a content management system or server more often, especially if you are actively working on a blog, website, or different project that needs constant maintenance or that requires frequent content updates or other changes. Avoiding this problem can be easy if you choose a dedicated/fixed IP address. It's a static IP address that only belongs to a specific device and does not change when you are in different locations. 

VPN service providers such as Private Internet Access can help you with these settings. This tool can help you control your online reputation and successfully manage your projects wherever you are. It is important to prevent different IP addresses from connecting to your website. With a dedicated/fixed IP address, VPN service, and secure access to a content management system, your project will remain secure.

Recover files damaged by a dangerous malware attack

Despite the fact that there are various circumstances that can cause data to be lost on a system, including accidental deletion, the most common reason people lose photos, documents, videos, and other important data is the infection of malware.

Some malicious programs can delete files and prevent the software from running smoothly. However, there is a greater threat from the dangerous viruses that can encrypt documents, system files, and images. Ransomware-type viruses focus on encrypting data and restricting users’ access to files, so you can permanently lose personal data when you download such a virus to your computer.

The ability to unlock encrypted files is very limited, but some programs have a data recovery feature. In some cases, the Data Recovery Pro program can help recover at least some of the data that has been locked by a virus or other cyber infection.
