IObit MBR Guard 

IObit MBR Guard is a tool that protects your computer from Ransomware's MBR attacks. A master boot record (MBR) is a special type of boot sector at the very beginning of partitioned computer mass storage devices like fixed disks or removable drives intended for use with IBM PC-compatible systems and beyond. Once the MBR is attacked, the malicious software will take over your disk and perform malicious actions like encrypting your data and asking for a ransom. IObit MBR Guard is designed to protect against the malicious attacks targeting MBR, like GoldenEye/Petya attacks.
