Which of the following viruses takes over the computer system when it boots and destroys information?
Answer: A
Correct answer: Boot infectors
A boot sector virus writes itself into the boot record, so it is loaded before the operating system every time the machine starts and can destroy data from a position where nothing is yet in place to stop it. A stealth virus is defined by hiding from detection, which is a different property, and a trojan does not replicate at all.
