    Offline virus scanners are standard. That’s always how you detect if you have been infected. Bios viruses are detected and removed by standard anti-virus software.

      BIOS and UEFI bootkits require special vendor tools and vendor signed firmware binaries to overwrite the SPI memory. Standard anti-virus software can not remove them, once they have been installed.
