A technician removed a virus from a user's device. The user returned the device a week later with the same virus on it. Which of the following should the technician do to prevent future infections?

Disabling System Restore is generally done to prevent malware from reinfecting a system via a restore point, but it does not prevent the initial or repeated infection from user actions.

User education is crucial for preventing recurring infections because human error, such as clicking malicious links or downloading unsafe files, is a primary vector for malware re-introduction. By educating the end user, they become more aware of risks and better equipped to avoid introducing the virus again through their actions.

Installing the latest OS patches is a fundamental security practice, but if the user keeps re-introducing the virus through their actions, patches alone won't prevent the recurrence caused by user behavior.

Cleaning the environment pre-installation usually refers to preparing a clean OS install, which likely occurred during the initial virus removal but does not address the user's future actions that lead to re-infection.
