Blzr1128's Config

Your config is just fine. A solid config too. Just incase install a sandbox like BufferZone Pro which i personally recommend.

Add a backup solution like Todo or Backup4all.

Last if you want you can install a tuner like Tuneup Utilities or Glary Utilities.
 
You can try Toolwiz Time Freeze which is a pretty good application that can undo changes in a isolate environment.
 
you could add malwarebytes and antispyware.

If you have many accounts Lastpass will help you out. WOT will give you a indication how website are.
 
since your already using Norton you could take advantage of identity safe for you password management. Overall good setup.
