It IS Impossible that there could be a Virus on your BIOS What exactly is happening that you come to the conclusion that this is the case?
If your BIOS has been corrupted by a virus, it can be fixed by re-flashing the BIOS with a clean firmware. This will completely re-write the chip and return it to operation.
Signs of a BIOS virus attack include failure to boot, changes to settings, and slow speeds. BIOS viruses are relatively rare due to modern safeguards.

No, removing the bios battery on a laptop will not reset bios settings.
Computer viruses mostly affect the operating system. I havent heard of any instance where virus affected BIOS settings. Although there are chances.

Scanning virus only help to find the virus inside your computer disks, but do no other actions, virus is still in your computer. But Removing virus not only find it, but also remove the virus from your computer. Thus no such virus will remain in your computer after that.

The origin of the "removing broadens your" virus is from Ukraine. It is a virus that will erase files completely and quickly, and therefore, prompt action is needed in its removal.
if you don't know what the password is you will have to reset the bios by tripping a jumper or removing the watch battery on the motherboard.

yes - If the BIOS of your computer is infected then, since it is hard-coded (firmware) on a chip, you could have irreparable damage. Also most anti-virus programs work within your operating system (Windows or MacO/S) so they don't detect BIOS infections. The only way to repair your BIOS is, if it can be, to Flashit. This is the process used to update the firmware on your BIOS chip. Check your computer or motherboard manufacturer to obtain the flash application, and the instructions for running it. Flashing the BIOS should place a new, uninfected version of firmware on the chip.
