Password Protecting The Normal.dot File
- - - - - ---------------------------------------
To password protect the Normal.dot file in Word 97, perform these steps:
1. Start Word.
2. Choose the Tools, Macro, Visual Basic Editor command.
3. In the Project window of the Visual Basic Editor, click on Normal.
4. Choose the Tools, Normal Properties command, Protection tab.
5. Check the Lock Project for Viewing check box and type in a password
6. Close the dialog box, close the Visual Basic editor.
7. Quit Word.
The next time you start Word, the normal.dot template will be protected.
WARNING: If you ever have to type in the password to make changes to the
normal.dot file be aware that the file remains unprotected until you quit
Word and restart it.
Turning On Macro Virus Protection and Other Options
Some simple macro virus protection is built into Word 97. It does not detect
specific macro viruses but only informs you if macros exist on a document
are trying to open. Macros detected by Macro Virus Protection are not
necessarily a virus. However, if you are alerted to a macro attached to a
document you should be extremely wary because most people do not have macros
attached to their documents.
Other options to set are:
Confirm conversions at open. This makes Word display a dialog box if
it is converting a document from one format to another.
Prompt to save Normal template. This makes Word display a dialog box
asking you to confirm changes to the Normal.dot template. Most
macro viruses hide in Normal.dot so this lets you know that there
has been a change that you may want to prevent. Changes also occur
when you change the default font or one of the built-in styles.
To turn on macro virus protection and these other options, perform these
1. Start Word.
2. Choose the Tools, Options command, General tab.
3. Check the Macro Virus Protection check box.
4. Check the Confirm conversions at open check box.
5. Choose the Save tab.
6. Check the Prompt to save Normal template check box.
4. Close the dialog box.
Whenever you open a document that contains macros, the macro virus
opens a dialog box telling you that there are macros in the document and
giving you the option to: Open the document with the macros enabled, open
the document without the macros, or cancel the open operation. You should
only open a document with macros enabled if you are expecting there to be
macros on that document and you know what they are supposed to do.
