Does this have a test mode so it can return a Status "Virus" on an attachment, without needing to use a file that has a "Virus"??
From the raised AVT
You can use EICAR which is a false positive that virus scanners know about but isn't a virus, I have used this for testing with inform attachments to check the virus scanner was working, see http://www.eicar.org/86-0-Intended-use.html for details about this. I would also let IT know if you are going to do work on this so that when it shows up on their monitoring it is already known about.
