The most common purpose for spamming is advertising. Goods commonly advertised in spam include pornography, unlicensed computer software, medical products such as Viagra, credit card accounts, and fad products. In part because of the bad reputation (and dubious legal status) which spamming carries, it is chiefly used to carry offers of an ill-reputed or legally questionable nature. Many of the products advertised in spam are fraudulent in nature, such as quack medications and get-rich-quick schemes. Spam is frequently used to advertise scams, such as diploma mills, advance fee fraud, pyramid schemes, stock pump-and-dump schemes, and phishing. It is also often used to advertise pornography without regard to the age of the recipient, or the legality of such material in the recipient’s location.

One of the most common ad spams is the computer software program GAIN. Also known as Gator or Claria or Dashbar, this insidious program hides itself within the active programs running on your computer and will collect information on internet habits. Based on the websites you visit, it will then send you “relevant” advertising at random intervals. Unfortunately, this program is often attached and automatically installed with popular “free” software, such as many P2P filesharing clients. Even removing GAIN from your computer can sometimes prove difficult, as it leaves traces of itself even after uninstallation or removal by third party spyware programs.

Spam has different levels of acceptability in different countries. For example, in Russia spamming is commonly used by many mainstream legitimate businesses, such as travel agencies, printing shops, training centers, real estate agencies, seminar and conference organizers, and even self-employed electricians and garbage collection companies. In fact, the most prominent Russian spammer was American English Center, a language school in Moscow. That spamming sparked a powerful antispam movement by enraging the Deputy Minister of Communications Andrey Korotkov and provoking a wave of counterattacks on the spammer through non-Internet channels, including a massive telephone DDOS (Distributed Denial of Service) attack.

The term adware frequently refers to any software which displays advertisements, whether or not it does so with the user’s consent. Programs such as the Eudora mail client display advertisements as an alternative to shareware registration fees. These classify as “adware” in the sense of advertising-supported software, but not as spyware. They do not operate surreptitiously or mislead the user.

Many of the programs frequently classified as spyware function as adware in a different sense: their chief observed behavior consists of displaying advertising. Claria Corporation’s Gator Software and Exact Advertising’s BargainBuddy provide examples of this sort of program. Visited Web sites frequently install Gator on client machines in a surreptitious manner, and it directs revenue to the installing site and to Claria by displaying advertisements to the user. The user experiences a large number of pop-up advertisements.

Other spyware behaviors, such as reporting on websites the user visits, frequently accompany the displaying of advertisements. Monitoring web activity aims at building up a marketing profile on users in order to sell “targeted” advertisement impressions. The prevalence of spyware has cast suspicion upon other programs that track Web browsing, even for statistical or research purposes. Some observers describe the Alexa Toolbar, an Internet Explorer plug-in published by Amazon.com, as spyware (and some anti-spyware programs report it as such) although many users choose to install it.
