Microsoft to launch bootable anti-virus/malware tool
This looks very interesting, and given that we have all, at one time or another been handed a computer or laptop that is so infected it barely boots, then Windows Defender Offline could be just the ticket. It's essentially a bootable (CD or USB) scanner that will dig out an infected Windows computer if it is too far gone (or risky) to connect to a network, and it will contain all of the very latest definitions (unlike other boot CD's). It's only in beta, but looks like a tool we'll all be getting familier with in the future.
