What Is Adware?

Adware infection rates continue to climb. McAfee detected over 14 million computers infected with Adware in the first three months of 2005. Adware refers to a type of program that is designed to serve advertisements to you while connected to the Internet. These ads are often considered a nuisance, and the adware program itself is usually installed by users accidentally, packaged in with other software that has actual benefit. Adware is often also referred to as spyware or malware. The worst examples of malware will even alter your browser settings, add unwanted Favorites links, alter system files, and create new default web pages. Finding Adware that has infected your computer can be challenging as new Adware programs are being developed constantly. In many ways, Adware programs are like a computer virus, with the goal of serving you pop-up and other types of ads, rather than causing other damage to your computer. Thankfully, there are a variety of Adware removal products available that can help you remove these unwanted programs. Matter of fact, it is recommended that you try out several Adware removal programs to make sure you have overlapping coverage, and that all detected Adware programs are removed.
Generically, adware (spelled all lower case) is any software application in which advertising banners are displayed while the program is running. The authors of these applications include additional code that delivers the ads, which can be viewed through pop-up windows or through a bar that appears on a computer screen. The justification for adware is that it helps recover programming development cost and helps to hold down the cost for the user."Spyware is any software (that) employs a user's Internet connection in the background (the so-called 'backchannel') without their knowledge or explicit permission. Silent background use of an Internet 'backchannel' connection must be preceded by a complete and truthful disclosure of proposed backchannel usage, followed by the receipt of explicit, informed consent for such use. Any software communicating across the Internet absent of these elements is guilty of information theft and is properly and rightfully termed: Spyware."
AdWare is also a registered trademark that belongs to AdWare Systems, Inc. AdWare Systems builds accounting and media buying systems for the advertising industry and has no connection to pop-up advertising, spyware, or other invasive forms of online advertising.
