Twelve million computers have been hijacked by cyber-criminals and detected by security vendor McAfree since January, the firm has said.
It reports there has been a 50% increase in the number of detected so-called "zombie" computers since 2008.

The figures come as a report from Deloitte said a global approach to cyber-security is needed.
"Doing nothing is not an option," said Deloitte's Greg Pellegrino.
