Here are my two rules:
1. Don't use McAfee
2. FOR THE LOVE OF ALL THAT IS HOLY DO NOT USE NORTON
But AVG is good, keeping an install of MalwareBytes around doesn't hurt either. (Although be aware that it won't filter downloads or whatever - no live protection)
let me echo everything Canama says here. Norton and McAfee are HORRIBLE. malwarebytes is also a good scanner.
Paid version of malwarebytes offers live protection, AFAIK.
yeah. I'd also encourage you to avoid TrendMicro.
I'm happy with Microsoft Security Essentials (or the built-in Windows 8 antivirus), but if Mak downloads a lot of stuff...Well, you could just use WOT to make sure he only downloads from safe sites, but if you want a paid antivirus I've heard good things about Kaspersky.
