VMware Horizon View AV protection

We're in the process of changing our AV protection over our whole company. We're highly virtualized in both server and desktop.  Currently we running View 6.2 with non-persistent (NP) desktops, but soon will be moving to 7.x and instant clones (IC).

We decided to abandon the agentless products using NSX because we get more protection with the agent-based ones. However, it "seems" that the ones we've selected to look at haven't quite figured out how to work with NP or IC desktops as well as they claim.

The bottom line for me is has anyone here actually used an agent-based product with NP desktops and more importantly with IC desktops where it just worked like it was supposed to work?  I really only interested in real world experience for this question.  Thanx...
