Personally I don't use any antivirus software, macOS has Xprotect and SIP to keep the system in check and if you need it MalwareBytes AntiMalware is free and scans on-demand to remove any adware showing you extra adverts online. Culprits include Geneio, Spigot and Vsearch which run in the background and inject adverts into web pages, earning the authors revenue.
I find common sense to be the most effective protection these days. I don't stream football from dodgy websites which require a software installation to work, I've removed adobe flash and use AdBlockPlus. I think a lot of the cases I've seen recently are when people get drawn in with fake flash updates which then install adware programs. As far as actual virus which gets into your Mac with no action on your part goes, I've not seen one in the wild yet. All the antivirus programs I've seen so far have been I'll-designed, badly optimised and problem-causing rather than fixing. Of course it's entirely up to you how you want to protect yourself online, you could try reinstalling avg or updating it to the latest version, or try Sophos (also free) instead.
