Hao123 is a famous search engine designed for the Chinese market. Users have started calling it “Hao123 virus” because it has been misused by various software developers and spread with the help of bundling. After using this technique to enter the computer system, Hao123 might alter your Internet Explorer, Google Chrome and Mozilla Firefox web browsers.[1] As a result, you may think that your system was hijacked, but, in fact, it is not.

In reality, Hao123 is not a virus. It was created by a well-known software developer called Baidu. However, its so-called “download client” has been actively spread together with other software, so there is no surprise that some users have been scared after finding it on the system. As a result, it can cause redirects to hao.123,,, en.hao.123, br.hao.123, tw.hao.123, jp.hao.123, vn.hao.123, etc.

In most of the cases, users download Hao123 Toolbar and similar components consciously from its official website. However, you can also let it enter your PC system when you fail to monitor the installation of download managers, PDF creators, and similar freeware. So, it is you are the one to blame if you found “Hao123 virus” on your computer.

This search engine is mostly propagated using bundling. It’s a software marketing method that allows spreading the program together with freeware or shareware as an optional component. The success of this method relies on the possibility to infiltrate the device unnoticed.

Just like any other search tool, the search engine collects NPII, e.g. search terms, most visited websites, data that added when visiting specific websites and so on.[2] As we have said, this information is considered non-personally identifiable, but we highly recommend keeping it private. However, only Hao123 removal will help you stop such activity on your browser.

The biggest problem that is reported about Hao123 client is that it might display you altered search results. Thus, instead of finding useful information, you might need to browse through commercial notifications and links leading to the sponsored websites.

However, it relies on the same distribution technique which is considered a little bit fishy, as it relies on bundling.

Bundling helps to install multiple shady programs at the time

Browsing on suspicious pages cannot give positive results since you are not guaranteed that there is nothing hidden on such websites, for example, scripts automatically allowing to download malware. However, automatic downloads can be encouraged during insecure freeware installation processes.

Pre-packed programs come alongside commonly gotten applications or even cracks of software, games. You cannot see those included applications if you skip through steps and allow installation to run automatically by choosing quick or recommended options.

If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.


Recover files after data-affecting malware attacks

While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.

Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
