The best thing is to be sensible. If you’re torrenting a boatload of crap then get all you can. If you’re just being a normal person and don’t have a tendency to click on “grannies in your area need love” banners then defender is just fine. Been using it solo since I got W10 and I’ve been fine.Or is windows defender sufficient on its own? If third party is needed what can you recommend (Ive used Avast in the past)
