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.
Consider CCleaner or Privazer
Some type of back up solution
I would also recommend adding some on demand scanners
Looks good!! Thanks for sharing your config
consider adding malwarebytes antimalware free for on demand scaners and ccleaner for privacy software
and adding these extensions to firefox ghostrey web of trust
Backup and Recovery is a must, having already an external HDD or performing backup using built in from Windows/third party program which better than nothing.
