Options

• ADisable System Restore.
• BEducate the end user.
• CInstall the latest OS patches.
• DClean the environment preinstallation.

Explanation

If a user repeatedly gets the same virus, the most effective preventative measure is often educating them on safe computing habits and how to avoid future infections.

Common mistakes.

• A. 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.
• C. 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.
• D. 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.
