Which of the following is not a primary trait of malware?

Answer: Diffusion

Explanation:

Malware is typically characterized by being booby-trapped or having malicious intent. While all malware shares a few primary traits, diffusion is not typically one of them. Malicious software can easily be distributed through the internet and other means, but it's not always easy to determine how it got there or who spread it. In fact, some malware authors purposely choose to disseminate their creations in an undetectable way in order to avoid detection.
