What is malware?

• A. Malicious software
• B. A type of hardware device
• C. A network protocol
• D. A data backup method

Answer: (A)

Malware refers to malicious software—programs created to damage, disrupt, or gain unauthorized access to a computer or network. It’s software, not hardware, a network protocol, or a data backup method. This category includes viruses, worms, trojans, ransomware, spyware, and other harmful programs that can steal information, encrypt files, monitor activity, or take control of a device. Malware often spreads through infected downloads, email attachments, malicious ads, or compromised websites, sometimes operating invisibly in the background. Recognizing it involves noticing unusual slowdowns, popups, or unfamiliar programs, and protection comes from keeping systems updated, using reputable antivirus software, practicing safe browsing, and regularly backing up important data.
