Norton makes your system slow, and Kaspersky likes to give a lot of false positives. I'd say Avast + Malwarebytes if you're concerned about having protection on your computer. But honestly, as others in this thread have said, windows defender and being careful can go a long way.
using premium version of avast. Works wonders and have a lot of neat features besides just the regular firewall many free ones offer. Bit pricey compared to.... free stuff... but its up to you, you'll always end up with better protection if you pay for any type of anti-virus. Its worth it to me, might not be worth it for you. All depends on how much you value a good antivirus.
