What is the best Antivirus for macOS in 2020 ?

I am using Avast for my macOS. I have not had any issues with it.... sometimes it slows down the mac but all in all its good.

I have a macbook pro and I am using Avira for about 3 years. I have had no issues such as slowing the PC and so on. I would recommend it.

Bitdefender Antivirus for Mac is one of the choices. This antivirus can protect files and emails in your MacOS, MacBook and MacBook Pro as well as iMac
