End-user education is crucial after malware removal to prevent recurrence. Teaching safe browsing habits and security awareness completes the remediation cycle.
Mark Soper - Mike Meyers' Lab Manualstates:
"Educating the user after malware remediation is part of the CompTIA malware response methodology. This includes training on phishing and safe practices."

The correct answer is B. Create and assign a security group with adequate permissions, because group- based permission management is the most efficient and scalable way to control access to shared resources. By assigning permissions to a group rather than individual users, administrators reduce administrative overhead and simplify future changes.
According to the Quentin Docter - CompTIA A+ Complete Study Guide, security groups are a best practice for managing access to files, folders, and repositories. Permissions are assigned once to the group, and users inherit those permissions by being members of the group.
The Travis Everett & Andrew Hutz - All-in-One Exam Guide explains that granting administrative permissions is excessive and violates the principle of least privilege. Applying permissions individually increases complexity and the risk of configuration errors, especially as team membership changes.
The Mike Meyers / Mark Soper Lab Manual further clarifies that mapping a network folder does not control permissions; it only provides access to a resource that is already governed by permissions. Group- based access ensures consistency, security, and minimal effort.
Because the requirement is to allow specific actions while preventing deletion-and to do so with the least amount of effort-creating and assigning a properly permissioned security group is the optimal solution, making B the correct answer.
