Online security expert AVG is warning computer users to be aware that they could be the weakest link in the security chain linking cyber criminals with your identity.

Lloyd Borrett, who styles himself as AVG’s security evangelist and is like a real-life Mad-Eye Moody, said this is called “wetware”.

“If the weakest link in the Internet security chain is the person in front of the computer, security experts are now warning that the rise of social networks is leading to a rise in social engineering,” he said, in a tone of constant vigilance.

“Just as increased security provision by automotive manufacturers means that to steal a car today you have to steal the keys, with computer systems now capable of being comprehensively protected, the easiest way to get into a home or business computer is now through its owner.”
