norton icon in task bar not responsive

to download windows updates i need to put Norton internet security in silent mode. I have done this for years.

now all of a sudden when I check until restart. it does not come back active after restarting the computer. if I click on it nothing happens and I can't start the program from programs in windows7

if I shut down my pc and then restart it comes back active.

why is this happening and how can I prevent it?
