Do-gooder Trojan has nasty bite

Downloader.Lunii deletes spyware, but is less friendly than it seems


Symantec is warning Internet users of a Trojan horse that removes spyware but alters the security settings in computers.

While Downloader.Lunii eliminates a variety of adware programs -- often known as spyware -- the Trojan also tries to maliciously change the setup of Windows PCs and then downloads files from unknown Web sites.

"It's common that a Trojan will try to change as much security as possible," said Nigel Beighton, Symantec's director of enterprise strategy. "They often try to change Microsoft, Symantec and McAfee software. But so far we've hardly seen it."

Symantec rated classified Lunii as a low risk Trojan.

Thanks for the info Okan.
