Alan, The only thing that sticks out immediately to me is your RAM, it is right on the minimum requirements for these applications. If there is any way to increase your machine's memory I would do it as it is the easiest and fastest method for improving overall performance.
The Virtual Technician will check if everything is installed correctly. Link in my signature.
Technical Support is available 24/7 via free online Chat (or email, but Chat is better), linked at top left of this page or in my signature.
As a new customer you are entitled to free telephone technical support for the first 30 days. See this link for information: http://community.mcafee.com/showthread.php?t=226996
That would probably be your best route right now. Might as well take advantage of the 30 days free as phone support is chargeable after that period ends.
If you ran the Virtual Technician prior to calling them give them the session ID #.
