Norton icon at upper right corner of desktop no longer appearing

Hi,

I'm running Internet Explorer 9 and installed Norton Internet security in April and noticed that a new box with six little icons  appeared on my desktop at the upper right corner which I assumed was part of the Norton software.  I noticed recently that it's no longer appearing on my desktop and was wondering if this is a problem. 

 

Can anyone explain this to to me?

 

Thanks,

Jack
