Are you speaking of anti-Windows virus software that runs on RH server?
Anti-Linux virus software isn't needed because there aren't any.

Sure, put this in a script:

logger "No viruses found"

and get cron to run it as frequently as you think you need.

You're probably not going to find anything like that because viruses
aren't usually the problem on Linux. Worms, and rootkits are more of a
concern than viruses.

If one of the programs running on your machine is vulnerable to an
attack, someone can use that vulnerability to gain access to your
system as the root user.

To help avoid this kind of vulnerability, install the latest patches
from RedHat on a regular basis using "up2date".

Also avoid running things on your machine as root unless it's necessary
to install or configure some software you know is safe.

To find out what programs you're running, hackers can scan the
available network ports on your machine. Take a look at your firewall
settings to make sure you're not allowing unnecessary access to your
system.

Once someone has access to root on your system, they can use a root kit
to cover their tracks and use your system as a platform to attack other
systems.

If you want to see whether your system has been compromised with a root
kit, there are tools for checking that. See http://www.chkrootkit.org/

Are there any Linux viruses in the wild? Or are you concerned about
passing on the weenieDOS ones that are everywhere?

Try Norman Virus Control http://www.norman.com

http://www.norman.com/News/Press_releases/19157/en

"Norman one of the world's leading providers of proactive virus
protection tools, announces that Norman Virus Control for Linux has
passed the ICSA Labs Antivirus test."

I've used Norman VC under OS/2 (which has no viruses) and it manages
to find the windoze viruses that I keep around for testing.

Unix systems typically don't use or need AV software. Viruses aren't
the problem they are on Windows due to architectural differences. What
you usually have on Unix systems is Tripwire and software like RedHat's
logwatch program. logwatch simply summarizes activity in the system
logs and reports it to the administrator, who can spot unusual activity
fairly easily. Tripwire monitors system executables and config files
and reports on any changes in them from it's baseline record of them.
Since those files shouldn't be changing when the admin doesn't expect
them to change, any attempt to install altered system programs or
change configurations typically show up in the Tripwire report. The
admin can then trace down the source of the change and replace the
changed files with good copies or otherwise repair the damage.

The Tripwire/logwatch approach has the advantage that they look for
things that any intrusion has to do regardless of details. Unlike
AV signatures, updates aren't needed and very very few new techniques
can avoid detection (the couple that I know reliably work aren't the
kind of thing that can be easily coded into a virus).

If so, two worth looking at are ClamAV (http://www.clamav.net/) and
F-Prot (http://www.f-prot.com/ but it is NOT free software). I've used
both and have no real complaints about either.

For native Linux/UNIX programs -- no (they are *generally* not needed).

For MessWindows applications hosted on a Linux server (eg Samba file
server) -- I am not sure if there are any *free* ones.

There are tools that scan for viruses in incoming E-Mail -- there might
be free ones (I think 'Mime Defang' does this, but I am not sure).

ClamAV is GPL and it works quite well. I also have used HBE+D AV
(Antivir) that is free for personal use.

The only people for me are the mad ones -- the ones who are mad to live,
mad to talk, mad to be saved, desirous of everything at the same time,
the ones who never yawn or say a commonplace thing, but burn, burn, burn
like fabulous yellow Roman candles.
