D'oh... You guys were spot on.

It turns out that Debian is just a bit too smart at times... They have 
their own config file with a few entries (inluding home_net) that it 
uses, instead of those in the snort.conf file.

Thank you guys for spotting this.


It's a bit weird though, that the rule fires at all, because from what I 
can gather from the server-logs, there are no Excel files on it, only 
Word Documents, and the Word Docuemnt that was downloaded when this 
alert fired, is not malicious according to www.virustotal.com so I doubt 
there is anything fishy in it.
