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".
Hmmm its about time they became a bit more pro-active instead of sitting on their arses expecting everyone to realise when their machine has been comprimised.
Its been a long time coming. BBC News Report
