which is the whole point

it's impossible to get them all catched with sgnatures because they 
change all the time and so if you want to be sure you need to treat 
every office macro as bad - they don't belong into emails these days

frankly i have seen companies blocking every .doc and .xls attachment 
with a reject info that you should use .docx and .xslx becasue they 
can't contain macros (would be .docm for the new formats)
