Default document template for Microsoft Word. That file commonly contains
the default margins and font settings and can be replaced with a template
containing things like a letterhead or your favorite letter format..
Normal.dot loads automaticly when Word is started directly (not when opening
by clicking on a Word document) or when creating a new document with the
Word toolbar icon. If someone replaces your normal.dot file they could
include a Visual BASIC for Applications (VBA) macro that could do mischief
in your system. Most people routinely set Word to NOT automaticly execute
macros when a document or document template is loaded to reduce the risk
from such exploits. Some antivirus software also has features to reduce Word
macro virus risks.
