I have a MacBook and an iPad and don’t use any virus protection as they told at the Apple shop it was not needed. I do know that if you don’t click on anything you shouldn’t, then you will be fine. Be extra careful with links everywhere. When I had my old laptop, pre Apple, I used Mcafee. I have Which so will have a quick look to see who they recommend. Mcafee low down on the list. Avast looks the best and they do a free one.
