I have managed to rectify the problem in the end by uninstalling and reinstalling my package. I tried to run the MVT tool but would not install as it said that Administrator policies weren't in place to install. However, the following was carried out:
Control Panel - Add/Remove programs - Removed McAfee
Ran McAfee cleanup removal tool
Manually removed further evidence of McAfee in Program files and Registry
Switched on Windows Firewall and reinstalled package from my account
McAfee finally installed and computer protected
This should have been something that McAfee should have advised rather than letting the customer spend all day doing themselves only to find there was a conflict with the old version NOT fully uninstalling when the new upgraded version was installed. Thanks McAfee - for nothing!!!
