My personal eXPeriences (

)
Bitdefenderpro = decent firewall, decent antispyware, more than good antivirus, basic optimization, pretty cheap
cons = can be resource heavy, antipishing isn't the greatest
ZoneAlarmpro = more than good firewall, one of the greatest antivirus
cons = annoying pop-ups, pretty expensive, recource heavy
Kasperskypro = one of the greatest antivirus, a more than decent firewall
cons = basic suite, recource heavy
Mcafeepro = decent antivirus, decent tune-up
cons = a bit recource heavy, basic defence, really bad firewall
AVGpro = more than decent antivirus, not so recource heavy
cons = really bad firewall, basic suite, some FP
Norton 360 v2pro = more than decent antivirus, firewall and tune-up
cons = expensive and however allready a bit optimized still a bit recource heavy
Pandapro = good antivirus, basic tune-up
cons = weak firewall, really recource heavy
Esetpro = not so recource hungry, more than decent antivirus, decent firewall (in comparison with the rest)
cons = really basic suite, antispam isn't super
Windows Live One Carepro = decent tune-up
cons = weak firewall, antivirus, antispyware
Outpostpro = strong firewall , more than decent antivirus
cons = also pretty basic
If I were you, I would go for Norton, eset or outpost
