Two consumer protection groups are asking the U.S. Federal Trade Commission (FTC) to investigate FastMP3Search.com.ar, a website that distributes software that can be used to search for digital music on the Web.The FastMP3Search plug-in disables the Windows Firewall, installs adware and Trojan horse programs, and generally hobbles the user\u2019s PC, said John Palfrey, the Harvard Law School professor who is StopBadware.org\u2019s co-director. The software is also virtually impossible to remove once installed, he added.StopBadware.org and the Center for Democracy and Technology plan to file a formal complaint with the FTC on Thursday. "We are asking the FTC to take a close look at an application that we consider to be the worst of the bad applications that we\u2019ve seen over the course of the last year," Palfrey said.Representatives from FastMP3Search.com.ar could not be reached immediately for comment. The website is registered to a company called Direct S.A., based in Buenos Aires, according to the Network Information Center Argentina domain name database. StopBadware.org was also unable to reach representatives from the company before filing its complaint, Palfrey said.The company\u2019s website tells users that the software will provide a fast way to search the Internet for downloadable music files, "in exchange for your agreement to also install our plug-in software, which may occasionally display ads on your computer."Although the FTC has sought court orders to shut down websites in the past, the fact that FastMP3Search.com.ar appears to be based in Argentina complicates matters, Palfrey admitted. Still, the FTC has worked on international efforts to fight spam and online fraud."When an application is hosted outside of the U.S., but is plainly affecting U.S. consumers, they can coordinate with other governments," Palfrey said. "We would hope that they would start an investigation of this application."FTC representatives could not be reached immediately for comment.Formed earlier this year with funding from Google, Lenovo Group and Sun Microsystems, StopBadware.org has issued reports on dozens of software products that engage in questionable or downright malicious behavior. It has exposed problems in everything from Kazaa to the Jessica Simpson Screensaver to AOL\u2019s free client.-Robert McMillan, IDG News Service (San Francisco Bureau)Related Link:\n\nU.S., Russia Agree to Shutter AllofMP3.comCheck out our CIO News Alerts and Tech Informer pages for more updated news coverage.
