Description of the Excel 2002 update: October 4, 2001

Microsoft has released an update to Microsoft Excel 2002. This update addresses a vulnerability that may allow malicious code to run in an Excel file without warning. Under normal circumstances, you receive a warning in Excel 2002 when you open a document containing macros. However, it is possible for a malicious user to modify the macros in such a way that a macro can run with no warning being issued. This scenario may cause damage to data or allow unauthorized retrieval of data from your system when you visit a Web site or open an e-mail message. After you apply this update, you will receive a warning before you open an Excel file containing macros.
