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.
