I currently use ESET Smart Security 8 (and only recently started it) and however biased this may sound, they don't give you a compromise for protection by reducing performance, so it's definitely light.
I used Kaspersky on both my laptops before, and for approx 4 years, but you can definitely feel it being heavy so it might not be good for gaming.
avast! is also relatively heavy, but I'm not quite sure why you'd want to use Premier, if the free version offers the same protection...
