I dunno... I find that AVG and AVAST just don't respect my exclusions properly. Those are the two most widely used free options. Most of the time I spent within the interface of antivirus programs is spent getting shit out of quarantine and adding exclusions for my bots and what have you, hoping it will let me do my work. So for now, I just avoid clicking on things I should not be clicking on, and run cracked apps from dubious sites withing a VM. I let Windows Defender run as well. Works for me.
