Browser Helper Objects are typically installed by other programs such as toolbar accessories and can track internet usage, create popup windows, display additional information on a viewed page and collect information that is transmitted by you over the internet. Malicious software that exploits this technology can replace banner advertisements with other ads, monitor your actions, change your home page, etc.
