Understanding Boot Sector Virus
A Boot Sector Virus is a program that interferes with the part of your computer or USB drive that helps it start up. Think of it like someone putting a lock on your house’s front door without you knowing, so when you try to go in, you can’t. This boot sector virus hides where the computer looks first to get started, so every time you turn on your computer, the virus wakes up too. It can slow down your computer, and steal your data. To stay safe, use antivirus software, be careful with USB drives, and keep your computer’s system updated.
What is a Boot Sector Virus? (Definition, Risks and Prevention)
A boot sector virus is a virus that infects either the boot sector of floppy discs or the Master Boot Record (MBR) of hard discs. The infected code starts when the boot sector virus system is booted from an infected disc, but once loaded, it infects subsequent floppy discs that are accessible in the infected machine. While boot sector viruses infect the BIOS, they spread to further floppy discs using DOS commands.
