Some irritations with Norton 360

I am experiencing a couple of minor irritations with Norton 360 at the moment:

1. I have recently installed Google Chrome so I can use the Chromecast. I opted for three Norton extensions: Security Toolbar, Safe Search and Home Page.  Now every time I launch Chrome I get a pop-up from Norton saying they are not enabled (they are) --- I have to enable them repeatedly

2. I welcome the Norton pop-ups which report that a download is 'safe' or 'not safe' but for a while now I have been repeatedly getting a pop-up to say that a component of Evernote 'is safe' ---- I have selected it as Trusted yet the pop-ups keep appearing

Are there any suggestions as to how I can stop these pop-ups?
