Is there any way within Perl to examine DOC and XLS files to

1) see if the document is empty, i.e. no text and no cell contents
2) has Macros embedded

We're getting lots of virus emails claiming to be invoices, receipts, etc. 
with documents that match the above criteria which actually contain a virus.

I'm trying to stop them.  

I know I can do the first bit for XLS files using Spreadsheet::ParseExcel, and 
I'm looking to see how to do this for DOC files.

However, I can't find out how to do step 2. The result I need to be able to 
run on a Centos / Exim setup.
