My computer got infected a while back and the only back up of some game data I have is on my flash drive, now I don't know if it's even infected but I don't want to risk it automatically jumping the second I plug in. I was told the virus was a Bios virus and It's gone from the computer now is there A. any chance it got to the flash drive and B would it jump to my computer or do I need to download the files before anything can happen?
