    I have not sat idly by waiting for answers and have made some progress as follows:-
    First to address system history/background.

    I did a format and network install of openSUSE_11.3 retaining my home partition intact.
    I subsequently for other reasons erased /home and set up new user.

    I installed kde 4.5.2 from KDE factory repo.

    I have, since my initial posting, uninstalled all clamav stuff and reinstalled from download.opensuse.org/repositories/security.openSUSE_11.3 and also installed klamav.

    Perhaps .kde3 was a figment of my imagination as I acnnot see it now but I still have .kde as well as .kde4. Is that as it should be?

    My desktop is kde 4.5.2 and it seems to be OK although it takes some getting used to and I have a few issues still to sort out, but back to clamav:

    Using Klamav I can now start the program.

    First issue on starting is an error message:- "Malformed URL media:/"
    Not sure how to stop this message but I guess it might be because there is no disk in drive. Is that correct and how should I stop it?

    Next issue is that from Klamav Update tab I can get newest database but I also get a message that I should update clamav. When I try using the button "Upgrade ClamAV now" I get message "could not contact upgrade server" I tried turning off firewall but still no joy. The connection it was trying to make was ftp.heanet.ie on port 80. So is that as it should be? I do not recognise it.

    Last issue is trying to enable Auto-Scan. It appears I must load module dazuko and rebuild kernel. Now from what I can find out it appears dazuko is proprietary software. I have never read anything about this in all my investigation of clamav so far. I shall need help setting this up if indeed that is what people use.

    If anybody has time to help me from here it would be much appreciated.
    Thanks again, Budgie2

    That's what I thought was happening to you and your system. It explains the ~/.kde folder (klamav).
    Dazuko can still be found, it's maintained by one of the Build Service users. To find it, and install it, go here:
    software.opensuse.org: Search Results
    In the Search Options, uncheck the "Exclude home projects...." option and search for dazuko. AFAIK you need both dazukofs and dazukofs-kmp-YOURKERNELFLAVOR


    That's all I can do for you at this moment.

    To most of your post, see DenverD reply, I concur with him. Saves "ink" :-)

    Clamav is normally installed from the default repos (not the one you used, that's an extra one), and
    there is a system service that, after enabled, automatically and periodically updates clamav.

    We *do not* use it. What for? That's the whole point. >:-)

    So, please explain why and what for are you using it, and then we'll try to help with the real
    problem, not your perceived problem.


    Hint: klamav being a kde3 application, and kde3 being old, (almost) unmaintained software, means
    that klamav has not been ported to kde4, means that klamav is obsolete and unmantained (pointy
    proven by your problems), so... >:-)

    Many thanks for the considerable time in addressing my queries and sharing some opinions too. I shall try and answer some of the issues raised.

    I want some sort of virus/trojan protection because, in my profound ignorance, I believe it possible or likely to become possible that a dodgy website could put malware scripts on my system while I am using a browser, possibly using java or flash downloads, and once there could access my network where there are other machines running which are not running Linux and may be sharing files which are private.
    This may be an ill informed view but that is why I am trying to set up clamAV.

    I have always used only the 4 recommended repo sites and only rarely depart from this rule, usually when so advised, for example when setting up multimedia as advised in this forum. We are however in a rapidly changing environment and I used the KDE repo at the time because kde 4.5 was not available from the "standard 4 repo sites". This may have changed now. Is that the case?

    Having installed kde 4.5.2 I found that the version of clamAV available from the standard repo sites would not run on kde 4.5.2. It was this attempt to install from standard repo sites which put some kde3 lib files on my system which threw me before. This may all have been changed by now. We shall see. Meanwhile I believe the kde version I have is not a beta after all but a full release, just not available from openSUSE at the time I installed it.

    In summary I have klamav running on demand but not as daemon and there are no instructions for setting up the config so although I can update virus database I cannot yet update the clamAV or KlamAV versions. There are good instructions for building kernel with dazuko on the klamavwiki but I am nervous about doing this because I am not sure I have the correct source code for the kernel I am running with which to build the modifed kernel with dazuko and I do not know (through ignorance) what happens to such a modified kernel when and if an online update includes a new kernel, which happens from time to time.

    If anybody can help me achieve my objective, even if they think it over cautious, I would be most grateful.
    Thanks again for all the advice and assistance.

    For one, this is an unlikely scenario, since critical bugs get fixed very fast thanks to the package manager. Furthermore, ClamAV would not save you from that - it scans for Windows viruses, nothing else. This is why I second DenverDs opinion insofar as setting up an antivirus in Linux is pretty much a waste of time and resources.

    That's doubtful, and even more doubtful that clamav finds them. Find a serious link proving that
    clamav does find viruses in linux, or that proves the scenario you describe :-)

    Hint: "on access" check is not supported by the kernel, it needs a hack (dazuko). If the kernels
    devs haven't provided that feature, it must be they think it is not necessary >:-)

    In fact, the "on access" method is used not to scan linux, but to scan directories shared by windows
    (via samba), to protect windows from virus put in the files written by other windows machines. Linux
    is immune, as far as we know.

    Yes, it can scan linux. Mostly as a placebo to calm down people claiming for an antivirus for linux :-p

    You are mistaken. Clamav runs well. What doesn't run is klamav, the kde3 wrapper to clamav. If you
    want to run an antivirus, learn to use clamav in the command line. That is maintained current.

    Hi and thanks for the further advice.
    As I tried to explain, my concerns are to protect other machines on my lan which are running samba or are samba clients and contain private info I wish to keep that way. Several are using windows os. I am sorry if I have not made this concern clear.

    I have noted the need for dazuko hack earlier and am not keen to go that way. I have no problem running command line clamAV but I was trying to address malware from websites not in email. Using websites often requires acceptance of scripts, even this forum for example tries to run a script.

    There is an article in Linux Format magazine (LXF 131) which includes some support for my concerns. It also proposes running clamAV but also mentions running clamAV as a daemon. That is the route I wanted and still wish to take and why I was put off by the dazuko hack.

    Meanwhile I have reverted to kde 4.4.4 which comes from the openSUSE repo. I shall now try a new installation of clamAV and see how I get on.

    Thanks for the help so far.
    Regards,
    Budgie2

    Ok, then what you need is on-access scanning on the shared folders (no more) by samba.

    Windows machines can only read what you export via samba, so what you have to do is configure samba
    to scan everything it writes. I know there is a module for this, but I don't know how it is done or
    configured. In fact, I heard there were some problems with this, perhaps the feature was broken.
