Boot Sector Virus

Boot Sector Virus: A type of malware that infects the boot sector of storage devices (like hard drives or removable media). Once installed, it is loaded into memory every time the system starts up, enabling it to persist even after a system reboot. It can potentially take control of the system before the operating system is fully loaded, making it particularly dangerous and difficult to detect and remove with standard antivirus tools.
