About this interactive
What you are doing: putting the startup steps in order to show the moment a boot sector virus takes control.
Why order matters here: the boot sector is the reserved area a computer reads first to find and start the operating system. A virus that infects it therefore runs before anything else — before the OS, and before the antivirus that might catch it. Loading first is exactly what gives it deep control and lets it hide, which is why the lesson calls it devastating.
How to use it: trace the sequence from power-on. The virus’s steps come early, and security comes last — by which point the virus is already resident and concealed.
What you'll learn
- Order what happens at startup to show when a boot sector virus seizes control — first, before the operating system and security software load
- Explain why running first lets it gain control of the system and hide from the tools meant to catch it
