Windows worm on the rampage
Holden has lost $A6 million in car production due to a Windows worm which also caused major problems in the US and Canada, AAP reports.
Holden was forced to shut down its vehicle assembly plant in Adelaide for several hours yesterday after its computer network was infiltrated by what is thought to be the Zotob worm.
Around the same time, the virus hit at least two Canadian banks and several major businesses in the US including DaimlerChrysler, ABC News, CNN, The New York Times, American Express, General Electric, Boeing, Visa and 250,000 others.
Holden said its systems were infiltrated early yesterday morning and the company stopped production until lunchtime.
Zotob affected various software programs at Holden, including those used to set up the computer chips in each car.
Spokesman David Ellis said the company would not comment on how the worm got into its computer network but technicians believed there were actually four or five different strains.
They were still working to identify which particular strain had attacked the Holden systems.
