Sony have done it again and introduced another rootkit, this time with a piece of USB hardware. For those that don't know what a 'rootkit' is. It is a mask or cloak used to sheild a piece of software buried withing the system or kernal that you don't want anyone to find. These rootkits have been taken up by virus writers and used to hide their nasty product from the increasingly sophisticated anti-virus and anti-spyware programs who can't find them because they can't see them. McAfee has just released a 'rootkit remover' and it is free to download and use. I would suggest anyone worried about security of their PC use it. Rootkit detection and remover. This works for all rootkits not just the Sony ones.
