We have the Enterprise version of NOD32 - without Exchange licensing. Reason being is we already own and use Antigen for Exchange and have no reason to replace that just yet. We need to have antivirus on the server, obviously. ESET is telling me I can't do this - that it is a huge risk. We were told by the salespeople that it wasn't a problem. I excluded all the files/directories from Amon that would hurt Exchange - per the KB article on MS. Only issue I see is with On Demand scanning - I don't see a way to exclude those directories. Otherwise what would the problem be? Antigen works too good for us to switch and I can't believe there aren't others out there who have this scenerio?
