Does updating bios remove infection
whether or not there is a hard drive connected in any way in the box...
Do you still think that it's basically impossible for someone to have a BIOS virus, or is it possible it could have somehow infected the memory or the video built into the motherboard?
Sure, flashing a BIOS is dangerous also, but in my mind not as risky as a newbie trying to pop out and replace a microchip physically.
This might be vital information: I got the RAM out of a old computer.If it's a case of re-infection even after reformatting the hard drive, it could be that there is a 'stub' of the virus in the boot sector of the hard drive. I have recently run into a rash of PC's that have lost their video abilities. This is not proof of a BIOS virus but we are very suspectful that this is the case. Shirley its job is just to load the OS from the HDD or CD and pass contol to it. Anything else the BIOS might have done in the past would be better supported by kernel modules in the loaded OS.Whilst there are several ways to eliminate this stub, one of the easiest I've used is to convert it to FAT 32, then back to NTFS. With that in mind, wouldn't the best thing be to write protect the BIOS flash and forget about it?To Fred (April 28, 2010 post), the virus warning they saw right before they lost video, was Not likely their anti-virus program.There is a virus out there right now that is a popup of a virus warning and to the user it will appear as if it is their anti-virus program telling the of it and to "click here" to get rid of it.
