Bios Virus or Fat Partition

During the course of the trial, the defense expert was talking about Trojans that were so deeply embedded in the machine that after a re-installation of the operating system, with Adaware and Norton Antivirus and then everything up-dated, it would remain active. In other words, what ever was on the machine would reactivate and conduct business as usual despite the properly re- installed and updated protection.
