What Is Search.hthecalendar.co?
An unwanted browser extension might get installed on your computer together with some free program you’ve downloaded from the web and set Search.hthecalendar.co (The Calendar New Tab Search) as your browsers’ new tab page and start page. Extensions that change these and similar browser settings are called browser hijackers. Their main purpose is directing more Internet traffic to specific search engines, in order to increase those engines’ ad revenue. The Calendar may collect certain data from browsers (what sites users visit, what searches they perform, etc.) and generate ads in browsers based on that data or sell this info to third-party advertisers. You may follow this step-by-step guide to uninstall the browser hijacker and remove Search.hthecalendar.co from your browser.
