Question

Which of the following is NOT a way that malicious code spreads?

a) Clicking on malicious links in emails.
b) Downloading infected files from the internet.
c) Simply opening an email message.
d) Inserting an infected USB drive into your computer.

Answer 1

Simply opening an email message (option c) is NOT a way that malicious code typically spreads. More risky behaviors include clicking on malicious links, downloading infected files, and using infected USB drives.

Step-by-step explanation:

The correct answer to the question 'Which of the following is NOT a way that malicious code spreads?' is 'Simply opening an email message' (option c). While it is possible for an email to contain malicious links or attachments that can lead to a malware infection, the simple act of opening an email does not typically result in a spread of malicious code. Modern email clients have safety features that prevent active content, such as scripts, from running when an email message is viewed. Therefore, unless the email client is compromised or incorrectly configured, merely opening an email should not lead to an infection. On the other hand, options such as clicking on malicious links in emails (a), downloading infected files (b), and inserting an infected USB drive (d) are all well-known methods by which malicious code spreads.
