Yesterday I upgraded my Norton Internet Security from the 2009 version to the 2010 one. This morning I noticed that the yellow NIS icon was missing from the system tray. My heart sank. I have had problems with this before and it took hours, even days to sort out. However, this time I came across this article at the Symantec Norton support site:
I downloaded the patch, applied it, restarted my PC, and the NIS icon is back again! I feel much better now. Malfunctioning security software makes me very nervous, almost paranoid.
