Computer Viruses mostly affect the operating system. I havent heard of any instance where virus affected BIOS settings. Although there are chances.
Afternoon 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.
depends if it infects the bios.
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.

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.
Windows uses Protected Mode, which (normally) prohibits raw access to a disk drive and other hardware. Also, if a system is infected with a virus, that virus would already be active, and may affect the performance of the utility (i.e. by hiding itself, disabling the scanner, etc). By using a utility that does not need Windows, you can prevent a virus from loading, which allows for a clean scan. Or if the utility needs direct hardware access, it can do so without needing elevated privileges and/or special drivers. Also, some motherboard functions, such as a BIOS flash, can only be performed in "unprotected mode", which is the BIOS's way of preventing a virus from infecting the BIOS (which would render the virus invincible, and/or completely damage the computer beyond repair).
sounds like you have a virus m8, check out symantecs website for more info

The real question is, how do you know your BIO's have a virus?If for some reason they really are corrupt. You will have to flash the firmware. If that's not possible the get another motherboard.
No. Updating the BIOS should have no impact on system performance, and thus should not affect your score.
