I would take eset over mcafee, the price this day isnt bad from 3rd party keysites. Apparently the sites selling keys that are attached to email of buyers, but it seems that doesnt affect into anything else, you can bind the key to your own email.
Eset looks like serious competer, you can manage it alot more
McAfee has its pros, light, doing good protection wise and installs in 20 seconds, is install & forget. But i miss the customisation with it, even its good it just dont feel like having antivirus at all, personally more the antivirus has settings to mess with its more fun for me
