Panda Labs is warning of a fake Microsoft Update e-mail designed to trick users into installing a Trojan.

"The e-mail, which Panda posts with a screen shot, is spoofed to look as if it comes from Microsoft Support," writes PC World's Eric Larkin. "With a realistic-looking subject and e-mail body that attempts to piggy-back on the constant (and correct) advice to keep your computer up-to-date with patches, it's a great example of a social engineering attack."

"Panda says unzipping and running the attached .exe would install the Bredolab.Y Trojan," Larkin writes. "And as an extra added bonus, it will also download a rogue antivirus program called SecurityTool."
