Your config is pretty strong!
I like it so much except 2 aspects:
-backup: you need to add at least a cloud solution or an USB drive which give you a more frequent copy of your data.
-browser: i would not keep Comodo browsers 'cause they're based on old engines, slower and more vulnerables compared to newest one. I would stick with basic Firefox or Chrome to always receive newest updates as soon they're out and combine them with a good adblocker (abp for FF, Adguard for Chrome) and a good privacy extension (Ghostery , disconnect), with an optional password manager if you need it
