Great overall real-time protection and on-demand scanners.
I would suggest
KeePass for securely storing your passwords, if you want to use a password manager. Read the security features of KeePass here:

As far as backus are concerned, you're good to go with Windows Backup for creating system images. Make sure you have a system image of a known good state of your system, so that you can use the backup image to restore that exact state in case of a software disaster (or malware infection).
Other than that, you're good to go. Thanks for sharing your config with us!
