Receiving a "Virus Scan Engine Connection Error" when using virusscan.xml

Over the last few days I've read through as much material on the virusscan.xml as I can find.  We've set up the AddAttachment functionality and virusscan.xml in our test environment, but can not get the virusscan to work.  No matter how I tweak the virusscan.xml we still get the connection error message whenever we try to upload an attachment.

xml parameters are as follow...
