The FBI is contacting more than one million PC owners who have had their computers hijacked by cyber criminals. The initiative is part of an ongoing project to thwart the use of hijacked home computers, or zombies, as launch platforms for hi-tech crimes.

The FBI has found networks of zombie computers being used to spread spam, steal IDs and attack websites. The agency said the zombies or bots were "a growing threat to national security".

The FBI has been trying to tackle networks of zombies for some time as part of an initiative it has dubbed Operation Bot Roast. This operation recently passed a significant milestone as it racked up more than one million individually identifiable computers known to be part of one bot net or another.

The law enforcement organisation said that part of the operation involved notifying people who owned PCs it knew were part of zombie or bot networks. In this way it said it expected to find more evidence of how they are being used by criminals.
