Dialer: Software that dials a phone number. Some dialers connect to local Internet Service Providers and are beneficial as configured. Others connect to toll numbers without user awareness or permission.
Backdoor: A secret or undocumented means of getting into a computer system, or software that uses such a means to penetrate a system. Some software has a backdoor placed by the programmer to allow them to gain access to troubleshoot or change the program. Software that is classified as a "backdoor" is designed to exploit a vulnerability in a system, and open it to future access by an attacker.
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.
Hijacker: Any software that resets your browser's settings to point to other sites. Hijacks may reroute your info and address requests through an unseen site, capturing that info. In such hijacks, your browser may behave normally, but be slower.
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.

Distribution:
May also use direct EXE file downloads to distribute the same dialers; this does not leave an ActiveX control loaded.
Prevalence:
Clot Factor:
The "Clot Factor" is a measure of how much a pest "gums up" a machine by adding registry entries, files, and directories. As more objects are placed in a machine, manual removal becomes more difficult and more error-prone.
