I've used ESET's various products for a number of years now as an antivirus/security package and have always been happy.
I'm not sure of the difference between the Family Security Pack and their other offerings, but it appears to be broadly in line with the Smart Security package, but with the inclusion of licences for Android security as well.
Here are the prices before and after discount:
ESET Family Security Pack 3
includes: 3 Computers + 3 Android Devices
12months - $84.95 down to $59.47
24 months - $124.95 down to $87.47
36 months - $178.95 down to $125.26
ESET Family Security Pack 5
includes: 5 Computers + 5 Android Devices
12 months - $109.95 down to $76.97
24 months - $164.95 down to $115.46
36 months - $230.95 down to $161.66
From ESET:

Msy is still cheaper afaik. Was $12 for a single 12 month licence last I checked
