Browser Helper Object: (BHO). A component that Internet Explorer will load whenever it starts, shares IE's memory context, can perform any action on the available windows and modules. A BHO can detect events, create windows to display additional information on a viewed page, monitor messages and actions. Microsoft calls it "a spy we send to infiltrate the browser's land." BHOs are not stopped by personal firewalls, because they are seen by the firewall as your browser itself. Some exploits of this technology search all pages you view in IE and replace banner advertisements with other ads. Some monitor and report on your actions. Some change your home page. Downloader: A program designed to retrieve and install additional files, when run. Most will be configured to retrieve from a designated web or FTP site. |
