You didn't mention what computer type you have, but if a PC using Win10, then I've been using Microsoft's standard Security Essentials (name may have changed recently) which is part of the Win10 setup. Although, I generally keep my music PC offline (using Airplane mode on WiFi), when I do connect, the updates to Security Essentials load quickly and easily. No nags!
