BIOS Viruses..?

Post by spinjector »

If a Windows-based host motherboard is infected with a BIOS-virus, can this affect/infect a Windows-based guest?

Only in as much as the guest relies on the host to carry out some functions.

Ok, are you saying that the BIOS virus on the host may not necessarily infect the guest, but may impede any BIOS functions that the guest may access?
