UsbCharger.dll in the Energizer DUO USB battery charger software contains a backdoor that is implemented through the Arucer.dll file in the %WINDIR%\system32 directory, which allows remote attackers to download arbitrary programs onto a Windows PC, and execute these programs, via a request to TCP port 7777. Per: http://www.energizer.com/usbcharger/download/March_8_2010_USB_Release__3_.pdf
"Energizer has discontinued sale of this product and has removed the site to download the software. In addition, the company is directing consumers that downloaded the Windows version of the software to uninstall or otherwise remove the software from your computer."
