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.
The Hao123.com website is not malicious or related to virus or malware infections, however, Hao123 client, with its deceptive means of promotion, is categorized as adware. Commonly, browser redirects to Hao123.com are caused by reckless free software installation. This browser hijacker is similar to other browser settings-changing adware such as istart123.com, v9.com, omiga-plus.com, and default-search.net To avoid installation of this adware, express caution when downloading free software since, today, most freeware download websites employ deceptive 'download clients', which trick computer users into installing advertised browser plug-ins together with the chosen free software. Advertised browser extensions rarely add any real value for the user, and moreover, often cause browser redirects and generate intrusive ads. When downloading free programs, closely inspect each step and decline installation of any promoted browser plug-ins. When installing downloaded freeware, select the 'Advanced' or 'Custom' installation options - this will reveal any bundled adware listed for installation and allow you to decline it. If you feel that your Internet browser settings were modified without your consent, use the removal guide provided to eliminate these issues.
