Norton Security 7.0 for Mac and OPSWAT

I've just upgraded from Norton Internet Security for Mac, to Norton Security 7.0 for Mac.

After this upgrade, I am no longer able to connect to my work via VPN. It fails to detect an installed Antivirus package.

I've been told by our VPN admin, that the VPN uses an OPSWAT SDK to check for an installed Anti Virus.

Has Norton Security 7.0 been certified with OPSWAT, and if so, what version does the SDK need to be?

Thanks
