Norton Utilities 16 application icon turns to unrecognizeable file

I recently purchases Norton Utilities 16 and installed and ran it. I have Win 7 Home Premium 64 bit. I pinned the application icon to the task bar to be able to find it easily. The product works terrific so far, but when rebooting my computer, the application icon on the task bar, the one in the start menu, and the original icon in the Program Files (x86) have all turned to an unrecognizable file icon. If I open it using the icon, NU starts and seems to work fine, but the icon turning unrecognizable is a little disconcerting to me. I read a post from 2009 for NU 14 having that problem by a user, and the moderator at the time said Norton would be addressing that issue in a future version. Any comments would be appreciated. Thanks!
