Here's what you wanna do. Enable UAC, Enable smartscreen to system-wide, use ublock origin instead of adblock. After you did that make sure you have a antivirus, you didn't list any real-time protection or on-demand scanners. If you want a free simple solution I would use WD and make sure real-time protection is enabled. Also if you test malware on your host machine be sure to use shadow defender or deep freeze. After you do all that you will have average protection, but if you want to be really safe I would add voodoo shield and zemana.
