Hao643.com – the heir of Hao123 hijacker

Hao643.com virus

Hao643.com functions as another Baidu-related search and entertainment website which virus researchers have categorized as a potentially unwanted program [1]. Upon further investigation, this PUP has been assigned to the group of browser hijackers along with Hao123, Hao.7654.com, hao.360.cn and a bunch of other Hao-based clone websites. The PUP:

  • replaces your homepage to hao643.com or hao123.com or baidu.com
  • has no proper privacy policy
  • contains links to shady websites overcrowded with ads
  • redirects you to poorly secured domains 

The veneer and modus operandi of PUP are identical to the mentioned sites – it infiltrates computers without any permissions asked and then starts modifying web browser settings. The PUP replaces default search engine and the homepage of the infected browser and starts loading every time the user opens a new tab or the browser window.

Since Hao 643 is Chinese website[2], users who don’t speak the language may find such behavior can get quite irritating. Even the Chinese-speaking users may get easily annoyed by this parasite simply because it sneaks on the computer without authorization. But the problems with this parasite extend way beyond the surface level. Hijackers don’t just infiltrate PCs for no reason.

They are created for very specific purposes, mainly focused on generating revenue [3] for their developers. So, while infected with Hao, you will probably start noticing an increase in the number of advertisements throughout your online browsing. 

Though some of these ads may be completely legitimate, others may not be as honest about the reliability of the products or services they are promoting. It’s just not worth trying your luck with this virus, so you should remove Hao643.com from your PC without much hesitation. Reimage or Malwarebytes Anti Malware might help you solve the problem faster.

Hao643.com redirect problem and the sudden burst of online advertising are some serious issues which must be addressed and fixed as soon as possible. But keep in mind that your PC may not be infected with this parasite alone, but hide additional malware which may prevent you from completing a full Hao643.com removal.

The hijacker may install these so-called “helper objects” to fortify its position on the system and prevent its extermination. Again, we want to emphasize the importance of employing automatic malware detection tools. The automatic system scan will ensure that no unwanted programs are left on your PC unnoticed.

Ways to promote the hijacker

Hao643.com can hijack computers by taking advantage of users’ poor web browsing and general lack of computing habits. The PUP may install along with freeware or shareware programs downloaded from untrusted web sources if the users do not opt for the Advanced installation mode and allow the setup wizard to install the downloaded software packages automatically. Thus, to stay safe from Hao643.com, you should be careful when obtaining new software and check the downloaded item for additional components that might travel along.
