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.

The Hao123 hijack is most likely to occur when users install new programs using “Quick” or “Standard” installation settings that do not openly disclose about additional components. Therefore, using this setup, you agree to install all programs that may have been included in the package.

Hao123 main pageHao123 affects search results which get filled with sponsored links and ads. If you end up seeing either of these pages, get to the removal immediately! 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. The research has shown that some of these affiliates’ sites might be used to promote malware.[3] Therefore, you cannot be sure whether some unexpected redirect won't trick you into visiting a dangerous or unsafe[4] website.

If you are done with this Chinese search engine, you can remove Hao123 from your device instantly with Reimage Reimage Cleaner Intego or another software. It’s the easiest way to get rid of all suspicious or even malicious components that might be installed on your computer.

However, search engines like this one are not hazardous cyber infections. Thus, you can also opt for the manual removal option.

Id.Hao.123 and ar.hao123 do not stand out much in comparison with other versions of Hao123. Their main aim is to promote the content of third-parties by displaying links and other vivid content. Here, you can find links to social networks, sports, news, and entertainment websites. Self-cautious users might get irritated by the fact that these links may redirect them to third party websites. is almost the same as Hao123 because they both belong to the same developer – Baidu. However, it relies on the same distribution technique which is considered a little bit fishy, as it relies on bundling. The site has also been providing links to third party websites, so make sure to double-check what you click and pay attention while installing new programs. 

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.

That's why experts recommend checking every installation window carefully when setting up any program on your computer. For getting such ability, always select Custom or Advanced installation of the freeware and then uncheck all questionable checkmarks.

    I have experienced that hao123 attached in IE and I did everything to clean it but still it show up as start page.
    I did uninstall, reset browser, clean registration keys. And finally I found that the hao123 was written after the ie dot exe file in property link target.
    if you right click on IE icon > property> target, you will see “C:/program file/internet explore”…., there delete the -hao123…- part. your IE should back to its home start page. it is very tricky.

    Hao 123 began on Firefox, which I rarely use, but then spread to IE after I had used it (not just opened it). After IE was affected, an IE-based browser began acting differently when I used it but did not have a changed homepage. So to minimize the damage/hassle, it might help not to use any other browsers before addressing the first infected browser.

    Probably the most conservative solution is to reset the settings of each infected browser — and write down your personalized settings beforehand. (If some of the infected browsers are superficial — e.g., IE-based — just reset their primary browser.) This worked for IE (uninstalling is impossible with Windows) & the IE-based browser. For FF, I just erased all of the programs files and reinstalled it. So far, no more hao 123.

    Hao 123 is not considered to be genuine malware by some people nor apparently by some reputuble antivirus programs; it is seen as more annoying than harmful. But its best to be safe.

    Ironically, browser speed seemed faster with hao 123.
