The Hohosearch.com program is from the Adware/ShortcutHijacker family of browser hijackers that is bundled with other free software that you download off of the Internet. Once it is installed it will change your installed browser’s home page and search engine to Hohosar.com without your permission. The method that they use to hijack your shortcuts makes it impossible to fix without specialized tools such as our Shortcut Cleaner.
