So I'd state from this config you only have 2/3 layers of security done, maybe 1 as Macrium Reflect could be a better source of backing up files to that in comparison of Google Drive, but I believe this is merely personal opinion and not fact.
You have a Firewall which is the default from Microsoft, you have a backup solution in the form of GD, however I believe you have inadequate web protection. I'd recommend Scriptsafe & Emsisoft Browser Security for your web browser and maybe twin Windows Defender with Configure Defender or OSArmor/VoodooShield. Most attack areas now revolve around email and web.
Take the advice as you will, thanks for sharing.
