Google in particular has drawn the attention of interlopers. Researchers for Lavasoft, which sells the popular spyware detection software Ad-aware, have identified one application that targets Google by altering the display of search results. The spyware, known as "Gloggle.Shing," carries a high threat level, according to Lavasoft, because the software installs itself in stealth mode when people visit certain Web sites, which the company did not name.
PestPatrol, another spyware fighter, has named "BrowserAid," along with many of its variants, as an application that affects search results. According to PestPatrol, the software installs itself via downloads from partner sites and delivers pop-up windows displaying ad links when a person searches at Google.
A hard look from LookSmart
And at least one publicly traded Internet company is trying to distance itself from yet another spyware maker preying on Google and other major search providers.
LookSmart, an online search and directory service, said it recently investigated its business partners in an attempt to discover which company had disseminated its text ads over those of Google. The partner had apparently linked it to a Web site called Clickthrutracking.com without permission, allowing that site to display LookSmart text ads over the sponsored results of Yahoo and Microsoft's MSN, as well as those of Google.
The company sent a letter in June to all of its partners, aiming to bar them from working with Clickthrutracking.com. The company would not disclose the name of the offending business partner, which apparently owns the domain Clicktrutracking.com. According to Whois domain name records, the company is called Search Request and is based in Phoenix. Calls to business license authorities in Phoenix and Scottsdale, Arizona, do not reflect a company of that name or address operating in the state. The company's Web site is intermittently out of service.
"We have a blacklist of sites that (our partners) won't allow traffic from, and that list includes Clickthrutracking.com," LookSmart spokesman Dakota Sullivan said. "They will screen that traffic out, and if it slips through, we won't pay for the traffic."
