Microsoft leads disruption of largest infected global PC network

Microsoft Corp said on Thursday it had disrupted the largest network of compromised personal computers, involving some 2 million machines around the world, since it stepped up its battle against organized online criminals three years ago.
The Redmond, Wash.-based software giant filed a lawsuit in Texas and won a judge's order directing Internet service providers to block all traffic to 18 Internet addresses that were used to direct fraudulent activity to the infected machines.
