I would consider a couple on demand scanners such as MBAM,Herd Protect,Emsisoft Emergency Kit,Hitman Pro,etc.
HTTPS Everywhere,uBlock,WOT extensions in Chrome
CCleaner or Privazer if not already installed
You can add another browser like Cyberfox in case you have a problem with Chrome.
You can also add a password manager like LastPass which is free to secure your passwords when you are online.
Thanks for sharing your config
