I have the same habits as you /PushPull, and I'm happy with the built-in Windows Defender plus Malware Bytes for an occasional manual scan.
Also, to keep cookies in check, consider setting up a cookie manager on Firefox. I use one called "Cookie Controller". Firefox is set up to reject cookies by default, then I select site-by-site which ones I'll let set cookies, and in most cases I'll only authorize for the current session (I.e. once I close the browser, they're gone).
