XL: Workbooks in Startup Folder Are Not Scanned for Macros

ID: Q180614

The information in this article applies to:

Microsoft Excel 97 for Windows
Microsoft Excel 98 Macintosh Edition

SYMPTOMS

When you start Microsoft Excel 97 for Windows, if there are any workbooks stored in either of the following folders

C:\Program Files\Microsoft Office\Office\Xlstart

The Alternate Startup File Location specified in the General tab of the Options dialog box

the workbooks are not scanned for macros when they are opened, even if the Macro Virus Protection option is enabled in the Options dialog box.

The same applies to Microsoft Excel 98 Macintosh Edition when workbooks are stored in either of the following locations:

The Microsoft Office 98:Office:Startup:Excel folder

The Alternate Startup File Location specified in the General tab of the Preferences dialog box

CAUSE

Workbooks stored in the startup folders are assumed by Microsoft Excel to be trusted. As a result, when you start Microsoft Excel, workbooks in the startup folders are not scanned for macros.

This behavior is by design of Microsoft Excel.

RESOLUTION

If you have reason to believe that one or more workbooks on your computer have been infected by macro viruses, perform the following steps:

In Microsoft Excel 97 for Windows, click Options on the Tools menu. In Microsoft Excel 98 Macintosh Edition, click Preferences on the Tools menu.

Select the General tab.

Select (check) the Macro Virus Protection checkbox. Also, clear the contents of the Alternate Startup File Location edit box. Then, click OK.

Exit Microsoft Excel.

Using the Windows Explorer, remove ALL files from the Xlstart folder. You can either delete the files, or you can move them to a different folder.

In Microsoft Excel 98 Macintosh Edition, use the Finder to remove ALL files from the Microsoft Office 98:Office:Startup:Excel folder. You can either delete the files, or you can move them to a different folder.
