One of my friends got a virus on his computer, he ran a bunch of anti-virus software but he couldn't get it all off. I told him that the last bit was probably in a Windows registry file and he would need to re-install windows. So he did that. But it didn't work. I went over to his place and looked at it and found that the virus was in the BIOS, we tried to flash the BIOS with a program I had on a thumb-drive but the virus was really weird and all the lettering was all fucked up with weird colors and characters so we couldn't find the place that would let us do that. So I figured to replace the BIOS, he had an old computer with (what we thought) was a similar BIOS so we took out the old one and put this one in. However now the computer wasn't posting a BIOS at all. So we then put the old BIOS back in and all of a sudden the virus was gone, the characters were back to normal and the computer showed no signs of being fucked up.
So exactly what happened? Is the virus really gone? If yes how could just taking out the old BIOS fix it, and if no then in what way is the virus still there?
