That still doesn't protect you against man-in-the-middle attacks or an attack against the CVS tree (like the recent kernel.org disaster). Signing the manifest files is really the only reasonable solution.

This page that I googled up shows a number of them: http://www.makeuseof.com/tag/free-linux-antivirus-programs/ Meanwhile, portage only lists clamav under app-antivirus/. The machine in question is running kmail to receive/send messages from ISP mail servers and ssmtp to send log messages for relaying via said ISP. What have you tried and what would you recommend for such a desktop setup? You don't need one. Linux anti-virus programs are there to protect Windows installations (Windows executables passing through a Linux box). Since you said Desktop, I assume you meant protect against Linux viruses. Since there aren't any Linus viruses, there's no need for something like that.

there aren't any Linux viruses, Except for the ones listed on the page below, which is probably incomplete. http://en.wikipedia.org/wiki/Linux_malware But yeah, on a linux desktop (especially a Gentoo one) you don't need a virus scanner. Yet.

And most malware runs an exploit to install itself, it doesn't require the user to run an installation program. So typical attack vectors are: network services, documents/media files (.pdfs flash etc), and all the usual web stuff. As stated earlier buffer overflows against Gentoo would be a nightmare to write due to the system variabilityRHEL not so much.
