Citation :Criminals are installing malware on PCs before they leave the factory, according to Microsoft.

Microsoft researchers in China investigating the sale of counterfeit software found malware pre-installed on four of 20 brand new desktop and laptop PCs they bought for testing. They found forged versions of Windows on all the machines.

The worst piece of malicious software they found is called Nitol, an aggressive virus found on computers in China, the US, Russia, Australia and Germany. Microsoft has even identified servers in the Cayman Islands controlling Nitol-infected machines.

All these affected computers become part of a botnet – a collection of compromised computers – one of the most invasive and persistent forms of cybercrime
