To secure my PC I have setup a BIOS password, preventing any access from a live-cd.
Recently I've noticed that when the BIOS asks for my password, I just have to press Enter to boot. It doesn't work if I type just anything, but it works if I type my actual password.
This situation is pretty worrying as it means that my computer is no longer secured.
The question is now, is there a way to check if any bios is affected, and if so how to clean it ?
