There are a lot of options out there, but I'm hesitant to recommend any specific offering, antivirus software is incredibly hard to test and all my recent experience (within the last decade) has been with enterprise offerings (products that can only be bought by organizations rater than individual consumers like you and I.)
Antivirus companies exist under the pretense that by having their software installed you are "Safe" but being safe is more about how you behave than what you have installed, and when computers are involved much of it is about configuration.
Generally speaking I'm fond of what the wirecutter has to say here:

I did martial arts for about 8 years and have two black belts (Hapkido and Tae Kwon Do) to show for it. The most valuable advise in those disciplines I was ever given was "You wana know how to win a fight against two guys in a dark ally?.. Don't be in a dark ally with two guys." With cyber security, much of the game is knowing when you are in a dark ally. Becoming educated about cybersecurity is truly the only way to protect yourself.
I will also say, having good backups that can be tested and having second factor authentication enabled everywhere are probably more important than having good antivirus software at this point. If you don't have one, I would strongly recommend adopting a password manager, and I strongly recommend 1Password.
