I get Norton Security Suite free because I subscribe to Comcast. I have never had any problem with it. A lot of people say it's a resource hog, but that doesn't really matter for me since all my computers are pretty solid. It does everything I need it to do and have no reason to stop using it. That's not to say I don't have Malwarebytes because I do, but just as a precautionary measure.
All in all, common sense is the best antivirus you can get.
