Antivirus API on Mac OS

I want to get the information of antivirus product installed on my Mac-machine. I'm developing an app which will show all system information, and I'm able to get system basic info, but not able to the get the security details, like what all antivirus/antispyware products installed in that machine.

I'm developing my app using Obj-C, and trying to get the api in that only. I want to call that api on demand, so it could directly embedded within the app or can execute externally as well. If I could get that command also then I could use that.

Does anyone know what API I should be calling please?
