Which of the following is NOT a common carrier of malware?

• A. A Freeware and shareware files
• B. B Email attachments
• C. C Files downloaded from the Internet
• D. D Dual inline memory modules

Answer: (D)

Malware spreads mainly through items that carry executable code or hidden payloads. Freeware and shareware can be bundled with malicious software; email attachments can deliver infected files; and files downloaded from the Internet can be infected. A dual inline memory module is a RAM hardware component. It doesn’t typically carry executable data or malware when you interact with it, and it isn’t used to deliver malicious software the way files and attachments are. So while hardware infections can exist in rare cases, they are not the usual or most common route for malware, which is why this option is the correct one.
