If an administrator modifies theVirus and Spyware Protection policyto disable Auto-Protect, but finds it still enabled on the client, the likely cause is that the setting was not locked. In Symantec EndpointProtection policies, enabling thepadlock iconnext to a setting ensures that the policy is enforced strictly, overriding local client configurations. Without this lock, clients may retain previous settings despite the new policy. Locking the setting guarantees that the desired configuration is applied consistently across all clients within the specified group.
