So while I have not had the time to create a view that would do this i have thought of a way to do so. You could do something along the lines of this:
Create a procedure that checks the status of Windows Action Center for the AV Status. You can use a WMI query for that. Save the output to a custom field in the agent. Then just create a view that looks for the no anti-virus result.
I know that is a very birds eye look at that issue, but it should work.
