Antivirus for ATM Machines

Traditionally, most ATM machines have been built on a core using the IBM OS/2 operating system. As the next generation of ATM machines is rolled out using Windows XP as its core and relying on IP networks to communicate with central servers they are seemingly at a greater risk of attack or being impacted by worms that spread across IP networks. For more about this potential new threat and the solutions that Trend Micro and Computer Associates are proposing see this article in The Register: ATMs in peril from computer worms?.
