In order to assist in demystifying desktop media services, we've provided a simple resource section with some basic definitions to assist the general public.
Adware vs. Spyware - Adware is form of client-side ad serving software that delivers advertising to consumers. Spyware is a software program that aids an unauthorized third party in gathering information about a user without his or her knowledge and consent. Spyware can then relay the information back to that unauthorized third party.
Desktop Media - Desktop media consists of a downloaded application that includes adware. Reputable adware discloses that it is adware during the download process, and provides for an easy uninstall facility.
Freeware - Freeware is software that can be downloaded and shared at no cost. Most freeware is copyrighted so programmers cannot use it in software they are developing. Adware is an advertising-supported version of freeware whose effects can range from benign advertisements into more threatening forms of spyware.
Parasiteware - Parasiteware is the term for any adware that by default overwrites affiliate tracking links. This behavior is viewed as parasitic because this software diverts affiliate commissions and credits the affiliate's income to another party. To the end user, parasiteware is not a serious security threat.
Spyware - Spyware is the dark side in the online advertising family. It is a software program that aids an unauthorized third party in gathering information about a user without his or her knowledge and consent, and then relaying the information back to that unauthorized third party. Spyware may arrive bundled with freeware or shareware, through peer-to-peer downloads, attached to or embedded in e-mail or instant messenger communications, or may be placed on your computer accidentally or deliberately by someone with access to it. Once on your system, spyware secretly installs itself and goes to work. Unlike personalization or session cookies, spyware is difficult to detect, and difficult for the average user to remove.
Thiefware - Thiefware applications steal affiliate commissions by either overwriting tracking cookies or spawning new windows to redirect traffic from search engine keywords or other Web sites. This practice, while not currently illegal, is considered unethical among those in the merchant/affiliate community.
Trojan Horses - Trojans are malicious programs that appear as harmless or desirable applications. Trojans are designed to be actively harmful to PCs by intentionally damaging PC operating systems, other software or hard drives. Trojans are generally distributed as e-mail attachments or bundled with another software program (often fraudulent versions of legitimate software).
Uninstaller - A program specifically written to remove a software program, most often included with the original program. Windows users can usually also uninstall programs through the Add/Remove Programs icon on their Control Panels. While most uninstallers come with legitimate programs, many privacy advocates consider uninstallers that do not remove all elements of a program (whether due to poorly written or maliciously coded) to be invasive and a possible indicator of Spyware.
Virus - A virus is a piece of programming code inserted into other programming to cause some unexpected and usually undesirable event, such as lost or damaged files. Viruses can be transmitted by downloading programming from other sites or be present on a diskette. The source of the file you're downloading or accessing from a diskette you've received is often unaware of the virus. The virus lies dormant until circumstances cause its code to be executed by the computer.
Web Bugs - A file, usually a small or invisible graphic image, that is placed on a Web page or in e-mail to allow a third party to monitor user behavior. While some businesses employ these as a valid tool for tracking Web performance, because users cannot see Web bugs, they are considered a form of Spyware. Unlike cookies, Web bugs cannot be rejected by changing the settings on a Web browser.
