Does anyone have an agent procedure that will work on the SaaS platform that will report the installed AntiVirus.

I've been trying to tweak this legacy script http://community.kaseya.com/xsp/f/114/t/5108.aspx but unfortuantly WMI seems very unreliable when reporting the installed AntiVirus so is proving difficult.. Does anyone have anything similar they are currently using successfully or have ideas on how best to accomplish this?

TIA - Luke
