I think Windows Defender and firewall are fine , along with Malawarebytes. The free version is not on all the time and has to be updated and run manually. IMHO it is the one item I would pay to have the Premium version. For me it has occasionally stopped PUP,s etc. It may prevent access to a few sites that try to download unauthorised extra. I have it on both my PC,s and on those of 2 adult grandchildren.
