Thank you Alan_B and DennisD for responding.
Dennis, I am not using PC Guard. I do have Zonealarm and Spysweeper running tho.
Alan, to answer your question on what happened after I re-installed Nokia PC SUite...
After Nokia Suite is installed, it usually asks the user for the type of connectivity to the mobile phone ie. cable, Bluetooth etc. This is done through a radio button that the user can select.
In the case of my PC, the radio buttons are not active. I cannot choose the connection of choice. This is where it ends. It isn't a problem with the USB driver as the USB services are working.
Any ideas how I can roll back or fix the problem??
