Norton Safe Web has stopped working in my IE8 only in one of three computers.

Hi folks,

 

For over a week now, my Norton Safe Web has stopped working in my IE8 only in one of my computers with Windows 7 installed, it is working in the other two computers with Windows XP Pro.

Even though it is turned on with a checkmark, I do not get the Site Safety green or other color icons any more. I do get them if I search using Norton Safe Search, though.

My O/s: Windows 7 32bit all updates up to date

Internet Browser:  Internet Explorer 8

=========================================
Norton Security Center
=========================================
Norton Internet Security
Version: 17.7.0.12
 
I have over a year left in my subscription and have gotten very used to keeping an eye on which sites are safe and which are not...

 

Can someone help?
