NIS 2011 Blank dialog box at startup

I think this is an odd problem here.  I recently reinstalled NIS 2011 due to some corruption with the program.  I used the Norton Uninstaller and then reinstalled.  Now, whenever I reboot the system, I get a blank dialog box that pops up after a minute or so.  it is a small rectangle with nothing written in it and it has an X to close it.  There is also a corresponding blank notification in the taskbar with a Norton icon and nothing else. 

 

I am running XP Pro SP3, and have never had a problem like this before.

 

Any thoughts?

 

Thanks in advance!
