Ik zou geen virus-scanner installeren, omdat ze nauwelijks voorkomen en het vertraagt.
zoals Vaagharses al zegt, is het ook nog zeer onwaarschijnlijk dat je het virus dan uitvoert onder root(als het tenminste iets wil aanrichten).
Trojans zijn er ook, alleen die kun je ook (bijna) niet binnen halen, met een uitzondering van "FreeBSD en Apache". Maar die was snel ondekt (md5sum).
Je bent dus wel veilig zonder virus-scanner.
(Met is natuurlijk altijd veiliger, dus zal ik nog even zoeken naar eentje)

mailscanner - An email virus scanner and spam tagger.
MailScanner is a freely distributable E-Mail gateway virus scanner
and spam detector. It uses sendmail or Exim as its basis, and a choice of
7 commercial virus scanning engines to do the actual virus scanning.
It can decode and scan attachments intended solely for Microsoft Outlook
users (MS-TNEF). If possible, it will disinfect infected documents and
deliver them automatically. It also has features which protect it against
Denial Of Service attacks.
Virus checking is disabled by default, spam checking is enabled by default.
After installation, you can enable virus checking, write your own virus
scanner or install one of the supported commercial anti-virus packages.
sanitizer - The Anomy Mail Sanitizer - an email virus scanner
The Anomy sanitizer is what most people would call "an email virus scanner".
That description is not totally accurate, but it does cover one of the more
important jobs that the sanitizer can do for you - it can scan email
attachments for viruses. Other things it can do:
Disable potentially dangerous HTML code, such as javascript, within
incoming email.
Protect you from email-based break-in attempts which exploit bugs in
common email programs (Outlook, Eudora, Pine, ...).
Block or "mangle" attachments based on their file names. This way if you
don't *need* to receive e.g. visual basic scripts, then you don't have to
worry about the security risk they imply (the ILOVEYOU virus was a
visual basic program). This lets you protect yourself and your users
from whole classes of attacks, without relying on complex, resource
intensive and outdated virus scanning solutions.
amavis-postfix - Interface between MTA and virus scanner.
AMaViS is a script that interfaces a mail transport agent (MTA) with one or more virus scanners.
AMaViS supports MTAs are exim, qmail, postfix, and sendmail, although this version has been built with only postfix support.
ik kan alleen iets vinden om mail te scannen(met apt-cache search virus)
