TOPIC 1: MALWARE TYPES
13 Questions • 13.0% of Exam • Covers various types of malware and their characteristics.
QUESTION 1
Malware
Answer: A malicious software.
Rationale: Malware is a portmanteau of "malicious software," referring to any software intentionally designed to cause
damage to a computer, server, client, or computer network. This encompasses viruses, worms, trojans, ransomware,
spyware, and adware.
QUESTION 2
Virus
Answer: Malicious code that runs without user's knowledge. Viruses require a user action in order to
reproduce and spread.
Rationale: Viruses are self-replicating programs that attach to legitimate files, requiring user interaction like opening an
infected document to execute and spread. This parasitic nature distinguishes them from other malware like worms, which
can propagate autonomously across networks.
QUESTION 3
Boot Sector Virus
Answer: A virus stored in the first sector of a hard drive and loaded into memory upon boot up. It is hard to
detect.
Rationale: Boot sector viruses reside in the Master Boot Record (MBR) or boot sector, initiating execution before the
operating system loads, making them difficult to detect and remove by conventional antivirus software. This pre-OS
execution allows them to gain control of the system early in the boot process.
