A new Trojan horse program that attacks and removes troublesome advertising software, known as "adware," is circulating on the Internet, according to antivirus company Symantec. The program, called Downloader.Lunii, was discovered earlier this week. When run, it attempts to kill off computer processes and delete files used by common adware programs like Powerscan and BargainBuddy. However, Lunii is not entirely benevolent. Like other Trojan horse programs, it also modifies the configuration of Microsoft Windows machines and attempts to download files from a remote location, Symantec warns.
