Get as many ESET accounts as you want here:
https://4fornod.net/#commentvk. They get blocked after like 1 month, but it's worth it. The quality ones that work are all the way down in vk comments. Just turn off your antivirus when going there, you can keep adblock. This is what I personally use. I like ESET because it doesn't delete system32 and my programs like Steam (shade to Bitdefender).
Other than that, use Windows Defender. It's good. And to be honest, no antivirus can save you if you download crap and act like everything is false positive. Use VM or RDP!
