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

how can i break bios password without remove cmos battery
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.
The function of a bios battery is basically to reset your bios if something goes wrong and you corrupt it. Bios batteries usually contain a little bit of information on them. Therefore, when you remove a bios battery, it goes back to default settings. **Note** removing a bios battery is usually a last resort to reset your bios. There are several other ways to reset your bios such as a jumper cable or (included in some never motherboards,) a reset bios switch.
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.
Neutralizing it and deleting it. Some anti virus software does this automatically.
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.
Usually NO, because the BIOS is in some type of ROM.However with manufacturers switching to EEPROM or Flash to store the BIOS (to permit updates without having to replace parts) there may be a small potential that some virus programmer may find a way to infect certain BIOSs on some computers.
If you mean the 'Quarantine' section of an anti-virus software by 'Virus Chest', then after removing it from there, it is permanantly gone....
Removing virus is a difficult job, you can install anti-virus software to remove it
sounds like you have a virus m8, check out symantecs website for more info
BIOS virus detection functions
Your best bet would be to just take the computer to Staples and have them remove the virus.
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.
