In my opinion, AVG has taken a few steps back over the years. If I were able to use a corporate license for MBAM (something I am still looking in to), I would have. One key I look at in anything I purchase is whether it has central control.
ESET is incredible control app with great support and allows you to do anything with the settings. And, the latest version has a server version which allows automatic exclusions of certain software and system files, which I dread so much, I didn't even run an A/V on the server. And, I found out first hand why you need exclusions if you run Exchange, etc.
So, my advice would be to pay for your base A/V with my bias of ESET Nod32, complement it with Malwarebytes Pro, run a weekly scan of each at different times and run real-time scanning all other times.
