I suggest you CCleaner and PrivaZer for privacy and maintaining and one of these programs: Paragon Backup and Recovery free, Macrium Reflect free or EaseUS Todo Backup free for system backup and recovery.
Good security configuration,if you want can add MBA (Malwarebytes) and ADW Cleaner.
The suggestions given by other people in this topic are sound, specially CCleaner and PrivaZer for privacy and paragon for backup.
In regards to a second scanner like MBAM while a great addition your config shows simplicity and with BD as your total package you got everything pretty much covered. As i said many times before a bit of brains, sound computer habits, sound browsing habits = happy computer.
