McAfee Pilot Protection is still the 'retail' level product. Corporate is EPO with 8.5i. But, like I said for retail products you can't go past Nod32 for consistantly good performance.
For the firewalls I prefer Sonicwall, Cisco's ASA is just another awful mishmash, Juniper was OK when they brought Netscreen but have done little to keep up the line at the mid to low end, Fortinet has so many issues its hard to know where to start. We rarely see watchguard here, it has been behind in UTM for so long and the box performance is pretty meak (according to utm benchmarks kicking around). They've all but disappeared off the market, but I have replaced a few watchguards with sonicwalls (tbh old models).
Quick and easy is nice with freeware, but given windows defender's poor performance the question you have to ask is are you really acheiving anything or helping your clients?
