Your config is too simple and basic.
You have to install a second browser, two on-demand scanner (such as MalwareBytes Anti-Malware Free), CCleaner, PrivaZer (for delete privacy traces), Auslogics Disk Defrag to improve the speed of your PC. Another suggestion could be BitDefender 60 second virus scanner, which is fast, light, and it doesn't take slowdown your machine.
Then you can also add some extensions and add-ons(HTTPS Everywhere, Collusion extension, which can allows you to know which sites are tracking your traffic), and a password manager, such as LastPass. Piriform Speccy would be another good addition
Then you'll have to install also a backup solution, such as Iperius Backup Free.
Thanks for sharing your config
