In large deployments, I have found Microsoft Forefront to be very effective at combating the majority of threats faced by our users. It provides the base platform for catching threats that would otherwise threaten our users and their data. If you have an environment that is under constant malware threat, then a secondary program may be needed as required.
The biggest advantage that MSF and SCEP provide over Norton is: One: Far less client overhead required. Both Norton and McAfee are highly intensive client side when in use. Two: We've had far better luck using the Microsoft system with its detection capabilities, versus the others. Three: It is tied right into the Microsoft updating system, which provides central updating capabilities of av/mal/windows updates.
