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. Bamital Botnet Shut Down By Microsoft and Symantec [bbc.co.uk]
