CFW + CAV (D+ Disabled)

Anyone here running CFW + CAV only with D+ disabled. Whats your experience? From how long you are running, any infection, false positives, system slowdown, default settings or custom settings, if custom settings what changes in the settings, do you find it better than other basic protection i.e other combo of same vendor or different vendor of firewall & antivirus, etc.

Thanxx
