If you're using Windows 10 1903 just download Hard_Configurator and Malwarebytes Windows Firewall Control. H_C properly setup(disable run as admin and instead use run by smartscreen, set default deny to ON and configure Windows Defender to HIGH settings). It should be enough if you have good security habits. Then you can use adblockers like uBlock Origin and Emsisoft Browser extension to protect against bad websites. And if you want an on demand scanner Emsisoft Emergency Kit is always there. I've been using these on my college laptop and it's super-light.
