Help boost browser security by disabling add-ons Many browser hijackings come from add-on software, also known as browser extensions, browser helper objects, or toolbars. These items can improve your experience on a website by providing multimedia or interactive content, such as animations. However, some add-on software can cause your computer to stop responding or display content that you don't want, such as pop-up ads. Internet Explorer warns you in the notification area of your browser if an add-on is slowing down your computer.
