You may ask if BIOS overwrites with every BIOS update. Will the BIOS virus that infected the BIOS be deleted in every BIOS update?
Yes, the BIOS is rewritten with a BIOS update. Rewrite or a BIOS update would erase the defects that some bad program or bios update would have caused.
As long as you are able to boot up the computer properly you are able to go online without any issues and as long as you are not getting any error popups while you are using your computer it means your computer is really working fine and it is not infected. So please ignore the bios update and other options.
As far as we know, there aren’t any viruses that can get into the BIOS on modern machines.
BIOS viruses are extremely difficult to get rid of, but fortunately, they are very rare. Since the BIOS is completely separate from the hard disks of a computer, normal virus scan software will never catch a BIOS virus.
It is possible for a virus to be written that hides in certain BIOSs, but BIOS virus is extremely rare.
