It was probably just a hiccup, I see that occasionally and it usually rectifies itself - click the taskbar icon to see if it works, open SecurityCenter and check if it's green.
Run the Virtual Technician to see if it fixes anything: http://mvt.mcafee.com/
If it continues, contact Technical Support - it's free by phone or online chat and linked under Useful Links at the top of this page.
Thank you for all your patience.
You're welcome Jerry. ;-)
