Here is what I have done and I'm not sure how to correct it or stop it. I have a program that searches drives for particular files and puts them into an Excel spreadsheet. The program starts, opens excel in the background, basically Excel is running as a process but I don't see it on the screen. The program does it's scanning and writes the data to the excel spreadsheet after scanning each drive. Once all drives are scanned it closes the excel file, saves it and kills the Excel process.
