The Us.hao123.com hijacker program typically bundles with other programs and files that are downloaded from a questionable source. Downloading objects online including freeware and torrent files can result in potentially unwanted programs infecting the user’s system. Even if a program is well known and trustworthy, if you download it from a malicious site it can lead to a computer infection.

If the computer user has previously downloaded a malicious program, Us.hao123.com might have automatically downloaded in the background without permission. The user might also be tricked into accepting the download under the guise of a program update or something else. Malicious publishers sometimes hide the download behind a terms and conditions page, effectively tricking users into downloading unwanted software and files. In some scenarios Us.hao123.com may be advertised as an extension to improve the user’s browsing experience in order to encourage a direct download or a necessary update for your media player, browser, or computer system. Regardless of how the system was infected, removal remains relatively unchanged.
