Does anyone have a good recommendation of what products to try for corporate AntiVirus, Spyware, and Spam protection Program? Prefereably with a gateway scanner to remove threats before they enter the network.

We are currently using Norton AntiVirus Enterprise Addition with Premium AntiSpam Add-On, but I can't help but feel like Norton is getting old and they really don't have any new innovations lately. My Subscription is up next month for our current Definitions and software maintenance and wanted to know what else I could try that was comprable. I of course know the names Mcaffe and Computer Associates, but don't want to waste my time trying them if they won't do what I need them to.

A few other wants/needs are that it be centrally managed, has some sort of alert system to report infections and threats, does not require a lot of user intervention.

Thanks in Advance!
