Whether I am trying to click on an email link or even a link in Microsoft Outlook Help, I am getting blocked with a message indicating that the operation has been cancelled due to restrictions in effect on the computer and to contact the system administrator. I am using Widows 7 and McAfee Total Protection. I have tried turning off McAfee, but it has no effect. I followed the thread listed to the left on this topic and it does not apply as I have not had anything to do with Google Chrome. This all started when I upgraded to Windows 7 from Vista. Any thoughts?
