That's fine. Any viruses there won't work on GNU/Linux, but if you're
concerned about what might happen to Windows users, you can scan with ClamAV
(the ClamTK package, found in Add/Remove Applications, gives you a nice
graphical interface for this).

Windows and GNU/Linux are not binary-compatible, so each system has to have
its own software installed on it. You can't run a program compiled for
Windows on GNU/Linux. In the case of LibreOffice, though, Trisquel already
comes with that by default, and of course it can read and write the same
document files (since it's the same program).
Remember that any new software should be installed through the software
repository, and this is easily your greatest protection on a system like
Trisquel from malware. Trojan horses can't get in because the only place
you're downloading software from has been put together and verified by a
trusted party. If you need something and can't find it in the repo
(Add/Remove Applications), come ask on the forum; there are a lot of
knowledgeable users here who can help. :)
