Change the security level for macro virus protection
 

Security  Because macros can contain viruses, be careful about running them. Take the following precautions: run up-to-date antivirus software on your computer; set your macro security level to high; clear the Trust all installed add-ins and templates check box; use digital signatures; maintain a list of trusted publishers.

  1. On the Tools menu, point to Macro, and then click Security. If you do not see the Macro menu item under the Tools menu, or the Security menu item under the Macro menu, click the arrows at the bottom of a drop-down menu to display the hidden menu items.

    Tip   If you want to see all menu items by default, on the Tools menu, click Customize, click the Options tab, and select the Always show full menus check box.

    6. Click Close twice.
  2. Click the Security Level tab, and then select the security level you want to use.
