Hint: The article “Keeping Secrets: How to Protect Your Computer from Snoops and Spies,” by Theo Callahan in the July 2007 issue of the Journal of Accountancy explains how to do this using Excel 2003. Review the article, and then use Excel’s built-in help function to learn how to do this with later versions of Excel.*
