A botnet that was believed to be illegally raking in more than $1m (£640,000) a year, has been shut down by security experts.
Teams working with Microsoft and anti-virus specialists Symantec raided several data centres in the US.
The firms said computers infected by the Bamital botnet were being used for identify theft.
Affected users - of which there were thousands - were offered free tools to help clean up the infected machines.
