I used to use NOD and it was OK but I didn't like the tag it put on all e-mails and they did not have live tech support for a small business application but I think they do know!
In case any of you ever seem to think that you might have a problem the other thing that I really like about Trend Micro is they offer a free service called House. House Call will do a free check on your system and you might be amazed at what it is able to find even those of you that are using a VP. Check it out and they offer a free Spam protection and keyboard encryption.
