Intel's vPro was supposed to have an embedded AV client in it, built right into the mainboard firmware on FLASH memory... This never materialized as far as I know... The thought was you could remotely connect via vPro, and do an offline scan of a systems HDD, without worry of infecting other machines. Intel then, was going to leave it to the OEM's (Mcafee, Symantec, etc's of the world) to build into...
I think strategically, this is a good move. But it'll be years before a real product materializes. Unitl then Symantec has got some time to come up with something.
