Have you registered this software and created an online account with McAfee?
Try running MVT again and even if it shows everything is ok, click on the prompt to contact Technical Support Chat. They can remote connect into your computer provided you give them permission to do so to see what might be causing the conflict and they have many tools they can use to diagnose issues such as yours.
Thanks k3tg, the problem has been solved. I discovered my internet service provided a Internet Security Suite powered by McAfee. Intstalled that and all seems to work like it's supossed to.
I feel better now. Grey mustached folks need stuff to be uncomplicated and enjoy the day. Neal
