Mocmex is a trojan, which was found in a digital photo frame in February 2008.
The virus is able to recognize and block antivirus protection from more than a hundred security companies and the Windows built-in firewall.
Furthermore, it spreads to other portable storage devices that were plugged into an infected computer.
[2][3] A large part of digital photo frames were manufactured in China, particularly in Shenzhen.
Mocmex happened just a few months after quality problems with toys manufactured in China raised the attention of Western countries leading to a low quality image for Chinese products.
