Explanation:

To prevent unauthorized access to personal details when using a public - library computer for an email account, logging off and keeping passwords secret are crucial. Updating the computer's anti - software (A) is more about the computer's general security rather than personal account security. Good netiquette (B) is about communication manners, not account security. Avoiding "finding" people (D) has no relation to preventing unauthorized access to personal information.

Answer:

C. He should always log off from an online service such as his school email account and keep his passwords secret.
