After a few hours on the phone with tech support we concluded that my machine will not run the McAfee Internet Security, so we removed it and installed the McAfee Virus Scan Plus package. Everything is good now!
Glad to know that....., if you have any other issues/concerns with McAfee product please do let us know or create a new thread.
