Any file can contain a virus. The only useful question is does the
program you're opening the file in have any exploitable vulnerabilities.
MS Word has shown that it's pretty happy to run whatever code it finds,
as in fact most programs are. I particularly like:
Valid attachments are; *.txt, *.pdf, *.svg
Plain text files are normally OK, but Adobe Acrobat has been the subject
of exploitable bugs and SVG interpreters are just as complicated.
Given that your email comes from a Thunderbird running on a Unix box
(or at least it says it's running through an X connection) a better
reason would be that you prefer not to use proprietary file formats. If
it's not the file format you mind about then I've had good luck with
OpenOffice and antiword--the latter should be simple enough not to have
too many exploitable vulnerabilities.
Everything else is ignored.
I'd love to live in a world like that!
