Select a policy and click the up or down arrow button to change its priority.
Drag a policy and place it at the desired priority.
Policies are applied in order from the highest priority to lowest priority. If you enable real-time scanning for more than one policy, only the policy with the highest priority is applied. The default policy always has the lowest priority and will be applied if no other policies are matched.
