Wha? Apparently the Energizer DUO USB battery charger contains a bit of malware, Arucer.dll, which allows remote system access on port 7777. CERT warns:
An attacker is able to remotely control a system, including the ability to list directories, send and receive files, and execute programs. The backdoor operates with the privileges of the logged-on user.
Energizer has removed the app from their download page and for most folks the DLL will be blocked by Windows Firewall, which is a good thing. The biggest question? Why does a USB battery charger need a Windows driver?
UPDATE – Here is much more on the topic. It looks like an honest to goodness Trojan stuck inside an Energizer recharger!
