Adware: Software that displays popup/popunder ads when the primary user interface is not visible or which do not appear to be assocaited with the product.

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.

Toolbar: A group of buttons which perform common tasks. A toolbar for Internet Explorer is nomally located below the menu bar at the top of the form. Toolbars may be created by Browser Helper Objects.

Trojan: Any program with a hidden intent. Trojans are one of the leading causes of breaking into machines. If you pull down a program from a chat room, new group, or even from unsolicited e-mail, then the program is likely trojaned with some subversive purpose. The word Trojan can be used as a verb: To trojan a program is to add subversive functionality to an existing program. For example, a trojaned login program might be programmed to accept a certain password for any user's account that the hacker can use to log back into the system at any time. Rootkits often contain a suite of such trojaned programs.
