Wondering if anyone here uses anti-virus software on their openSUSE computer and if so which one and also whether it’s caught linux-directed viruses.
Hi,
IMO, you don’t need it. 
Please search the forum on the innumerable and quite futile threads on this thematic.
To make a long story short: it makes sense to use a free anti virus in Linux to detect Window-email viruses on a linux server installation that serve also windows client in the net in order to protect them.
There are AFAIK no existing useful anti virus for Linux malware. The number of know potential viruses for linux is practically zero (very few and not know to be infectious in the wild).
If you want to avoid threat from worms and troyan horses as well as root kits do the following:
- do not grant physical access to you PC / server
- do all the necessary security updates
- use secure file permissions if applicable and avoid scripting if the machine is very mission critical.
- there are several root kit control solutions like rkhunter and others.
- use only software out of the controlled repositories.
- avoid adobe (reader-flash---------)
- use noscript plugin in firefox.
- set up correctly AppArmor or Tomoyo
- consider the use SE-Linux
Good luck.

no, of course not…(there is no need, unless you want to help some
windows users protect their machine–but, ask yourself what they are
doing to help protect YOUR machine???)

no, of course not…(there are none)…

May I add
- don’t log in as root …
or was it already obvious?
No more windows partitions in this household… so nope. The only virus known to me is me and my typing…
So far, I’m in line with everyone else. I NEVER log in as root (obviously I use sudo, but I’m careful with that). But…while I do believe Linux is a safer environment than windows (again, if you don’t log in as root), it’s not unhackable/immune-to-viruses. I think right now, it’s no problem but since pretty much 100% of Tablet computers are now unix (BSD/linux) based (Mac and iPhoneOS are FreeBSD based) and almost all new smartphones are linux based, I think attacks on linux are going to start increasing.
Oh no my GPS is going to get a virus?
Phones are a different attack vector, all boils down no matter what platform your on… it’s only the user/admin that presses the button to accept/do something.
Linux might not be imune to viruses (who knows?), but as long as there is none known, there can not be a AV program that knows about it. Unless you believe in wichcraft.
Only to recover windows computers that were infected by viruses.
And furthermore, if there were a threat (Trojan or rootkit maybe), only the /home folder would be affected. That is why it is SO important to not log in as root.

None in 13 years.

I did not want to offend the OP. Not log in as root is as saying: “to avoid reduction of your life expectancy, avoid shooting yourself with a gun into your forehead”.
Of course not. Antivirus??? What is that??
Windows!=LINUX
As our threat author seems to be interested in security issues and malware. The following links may be useful for learning about rootkit detection and malware checking on your machine without wanting to be complete. Please feel free to add interesting links to security pages and useful monitoring programs.

If you want it tough tough and complete:

You may wish to control for your network traffic. Have a look here to do this efficiently with wireshark:
Wireshark · Go deep.
this program can be also useful to improve your firewall settings.
Then if you wish, look at a program helping you to “harden the box”:
BASTILLE-LINUX
If you have several users on the machine and want to define permissions in a more efficient way you may have a look at policy kit that is also contained in Opensuse:
freedesktop.org - Software/PolicyKit
You may change your ssh port to a personalized one (if you need and use ssh). A good maximal is to have only services running that you REALLY need and use.
Oh yes, do not login as root, do not post your user and root password on websites and do not install the “ultimate free video codec for seeing this excellent xxx rated illegal warez film”. Not even when you receive an email from “Mikrosovt-customeer-service@nigeria.org”! I guess that was obvious.
Good luck. Please feel free to add if I missed good pages, as said already above.

Thank you very much,
you seem to be expert on this issues so let me ask you to make this explanations more simple
as simple as ordinary users (like myself) could understand
after long period of Windows, am trying to understand Linux using Suse
of course would like to be protected****
Thanks again
It’s this simple
No virus worries in Linux!
Re: **stakanov’s comments
**Self explanatory really or just google the phrase term for more info
All I would add is: Don’t login as root
how do i do or do not that?
what means login as root
