Answers
D.
Reinstalling the OS. flashing the BIOS, and then scanning with on-premises antivirus
Suggested answer: B

Explanation:

Flashing the BIOS, reformatting the drive, and then reinstalling the OS is the best method for returning a computer with a malware infection to service. Flashing the BIOS updates the firmware of the motherboard and can remove any malware that may have infected it. Reformatting the drive erases all data on it and can remove any malware that may have infected it. Reinstalling the OS restores the system files and settings to their original state and can remove any malware that may have modified them. Scanning the system with a Linux live disc may not detect or remove all malware infections. Degaussing the hard drive is an extreme method of destroying data that may damage the drive beyond repair. Reinstalling the OS before flashing the BIOS or scanning with antivirus may not remove malware infections that persist in the BIOS or other files.
