Last week I posted a warning about Sony music CDs installing a rootkit
on PCs. The situation has now escalated, with viruses released which
exploit the 'hole' introduced by the rootkit - see here for details -

http://www.theregister.co.uk/2005/11/10/sony_drm_unmasked/
The latter gives a number of links which provide the whole sorry story.
