Good Antivirus solution
Problem reported by Manuel - 8/20/2015 at 11:01 PM
I have SmarterMail Enteeprise 14.2
I have many problems with ClamAV.
Many times viruses are not detected (especially when contained in zip or rar).
Many times ClamAV failes scand and I find this error on log:
Unable to run Clam virus checks: System.Net.Sockets.SocketException (0x80004005): No connection could be made because the target machine actively refused it
I search definitive solution for a good antivirus.
You have any suggestions on a good antivirus to integrate with SmarterMail ?

solution provided by Joe greatly improves ClamAV performance (I'm also using it - paid version - on all of my gateways).

Here you have stats for yesterday (21.08.2015) one of three gateways which I use:

Running ClamAV managed by SmarterMail caused my a lot of issues and starting ClamAV as a separate service fixed all of them.
