The "big" risk (although still negligible) is that someone will mail
your users an executable that does something bad. But, you would have to
save it under /home, chmod +x it, and then run it manually for it to be
dangerous.
If you use portage to install packages, you should not ever need to
chmod +x anything. It's a big red flag and normal users don't even need
to know how to do it.
Mount /home noexec for extra safety.
Note that antivirus wouldn't help anyway if your users are going to do
whatever the email says without question =)
