Had the same issue. Should be supported in ESAP 1.8.0.
I ran a quick test with the AVG Free Anti-virus 2012 and did not have any issues with host checker detecting the software. My configuration was only checking for last anti-virus update. If you are running ESAP 1.8.0, I would suggest open a ticket with jtac so we can test the SA configuration against our lab to see if we can replicate the issue.
The version of ESAP is at the very bottom of the Endpoint Security page.
