Thanks so much, Broni, your assistance has been invaluable and much appreciated!! 
Actually I do have another issue. I have decided to remove Spyhunter 4 due to it's somewhat sketchy reputation. I have used the add/remove software option from the Windows Control Panel. However, there are still files and folders in my Program Files and they are resisting deletion.
Do you have a method for a thorough removal of this software, or can you point me to link which describes how to do this?
