The job of handling such specific system codes should be left to the developers of the specific motherboard model, who release BIOS updates along with specific tool to update the BIOS code,” he further revealed. “Developing an antivirus utility able to clean the BIOS code is a challenge, because it needs to be totally error-proof, to avoid rendering the system unbootable at all. “Storing the malicious code inside the BIOS ROM could actually become more than just a problem for security software, given the fact that even if an antivirus detects and cleans the MBR infection, it will be restored at the next system startup when the malicious BIOS payload would overwrite the MBR code again,” stated a researcher from Webroot.
