I was doing the same thing last night at 11:30.  Norton flagged over
100 instances of Klez on my sister-in-laws business computer.  There
were at least a dozen others, including a keylogger, backdoor, and at
least 8 other trojans, but Klez was definitely the most proliferated.
Fun, ain't it?

> Any suggestions?

As suggested by another poster, Clam-AV.  I use it and it catches all
kinds of nasties.  There is also f-prot, which you can set up as a
backup scanner through Amavisd-new.

I use Amavisd-new with postfix as my SMTP server, but if you're using
Sendmail, there may be other options you want to check out.  Start
with the handbook:
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/index.html
particularly chapter 4, if you're not familiar with the ports, and
chapter 22 to get a good overview of the options involving email.

Good luck
