'Fix Now' not running automatically at system start

Hello,

Since tech support chat was not able to answer or fix the issue, even after remote session with them, I'm hopeful I can find the answer here.

We have Norton Security on 2 PC's (Win 7, Win 10), and 3 laptops (Win 7, Win 7, Win XP).

On all machines, after starting them up, usually after haven't been on it for a day or so, the system tray shows the Norton icon with an exclamation mark. When clicking on it the usual small Norton window opens with 'Attention - Your PC needs to be scanned for viruses and spyware.' and a 'Fix Now' button.

Question: Why would that not run automatically at system start, or at least, run at some point during that session? Is the setting for that buried in some setting I am unable to find?

Thank you,

Stefan
