What is Hao123.com?
The Hao123.com website was created by Baidu (one of the largest web services companies in China). This is a legitimate website, which enhances Internet users' browsing experience by providing easy access to trending sites, quick Internet search access, etc.
While this site is not malicious, many computer users refer to it as the Hao123.com virus. These associations are made since the site is promoted using 'Hao123 client', a program provided as free software. This software modifies Internet browser settings and sets Hao123.com as the user's default search engine and homepage.
Hao123 client is promoted via free download websites using 'download clients', which offer installation of additional promoted software to users downloading freeware. When installing free software downloaded from the Internet, users are advised to inspect each installation step and select the 'Custom' or 'Advanced' options, rather than 'Quick' or 'Typical'.
After choosing advanced installation, ensure that you opt-out of installation of additional browser toolbars or add-ons and disallow any suggested changes to your Internet browser settings.
