The findings come from a collaborative SpyAudit report that analyzed Scans of PCs during the first quarter of 2004, revealing more than 29.5 million instances of spyware. While the majority of infiltrations are benign forms of adware, there are roughly 185,000 cases each of system monitors and Trojan horses [define].

The spyware issue has been getting attention both on the federal and state levels, where legislators are considering legislation that would restrict the invasive practices. But some Internet companies believe the statutes are too restrictive. Adware company WhenU filed suit against Utah, claiming that the state's anti-spyware statute is unconstitutional.
Internet users are also under siege from "Web beacons" [define]. Traditionally used by legitimate Web marketers, these e-mail tags are now being heavily adopted by spammers. According to e-mail defense Solutions company MX Logic, Inc., nearly half of unwanted messages contain these beacons, which spammers use to validate e-mail addresses and detect activity.
MX Logic analyzed that e-mail messages that were identified as spam by its filters and by customer quarantines from the prior 12 month period, resulting in a sample size of nearly one billion e-mails. Through this process, the company determined which bugged messages were considered spam.
Typically, Web beacons, or "bugs," are quite common in e-mail since e-marketers rely on them to provide results of e-mail campaigns. "We see Web beacons in a fair amount of messages. There are legitimate reasons for Web beacons, such as tracking activity, measuring click-through rates, inserting cookies for personalization," says Scott Petry, founder and vice president of products and engineering for Postini, an e-mail security company.
Significant portions of bulk mail messages may contain a beacon, but not all of it is unwanted or non-opt-in. Petry explains that all mass mailers -- legitimate or otherwise -- use Web beacons to report metrics and results to customers.
