Yes it's possible for a virus to attack the bios.
Yes it will survive a disk wipe.
It's a bios specific thing so not a good way to deliver a payload to the masses.
More likely the bug is on the hdd.
Create factory restore media...read the manual.
Run a pass of dban....not much will survive that.
Restore from the created media....read the manual.
I read on another post in this forum that viruses can survive disk wipe. I'm curious if I can use factory reset which will suffice, as they stated that the virus can affect the BIOS and remain in the disk.
