A user's personal computer was infected with malware that had a known remediation. Which of the following should the user have done to prevent this issue?

While creating a restore point can help revert the system to a previous state after an infection has occurred, it does not prevent malware from being introduced in the first place. A restore point is a reactive measure rather than a proactive one and does not address the underlying security vulnerabilities that malware exploits.

Maintaining a preinstallation environment can be beneficial for system recovery, but it does not actively prevent malware infections. This option is more about having a backup recovery solution rather than establishing ongoing protection against malware threats, which is essential for prevention.

Disabling System Restore can actually increase the risk of malware infections, as it removes a potential recovery option for the user. This choice would hinder the user’s ability to revert to a clean state after an infection, making it counterproductive in the context of prevention.
