      Sanesecurity, good to see you here!

      I have several. How would you like me to get those to you?

        Any insight on my previous post? Set it up as instructed. The DB's all update, and I checked the DB's were there. But I don't see them being applied. Also doesn't seem to be blocking anything more in my tests.

        This is what my DB says…

        Squid Version   3.5.19_1
        Antivirus Scanner   ClamAV 0.99.2    C-ICAP 0.4.3 +  SquidClamav 6.10

        Based on the logs you posed above it looks like its working. I don't get the additional databases showing up in the dashboard widget either, but I know they are working due to the blocking happening. Also when I run freshclam I see them updating.

        I'm guessing the Squid Antivirus Widget doesn't report on custom databases, would be nice to have that fixed.

          Good to know it's working and you have the same thing happening. I did try to open that link you posted with the icon.lsr and it did let me download it. On the WICAR malware test page, I get some blocks so I do know ClamAV is working.

            You can copy/paste the links and I'll download them with wget to test.
            or perhaps you can pop them into dropbox or some other file storage and send me the link.

            Cheers,

              If you run a freshclam and see them updating then they are in there.  What if you download a file to the box and run a clamscan on it?  If it catches it then it may be a proxy integration thing.

                2 days with no more of the FP's. Looks like they are fixed, thanks sanesecurity…

                    Is there a way i could whitelist a specific website in clam .conf files?

                      I also forgot to mention once you do load advanced configuration the settings on the page will be void.

                      So if you want to disable clamav scanning streamed audio/video while advance mode is enabled you can add this code to the end of squidclamav.conf

                      Do not scan (streamed) videos and audios

                      abort ^..(flv|f4f|mp(3|4))(?.)?$
                      abort ^..(m3u|pls|wmx|aac|mpeg)(?.)?$
                      abortcontent ^video/x-flv$
                      abortcontent ^video/mp4$
                      abortcontent ^audio/mp4$
                      abortcontent ^.audio/mp4.$
                      abortcontent ^video/webm$
                      abortcontent ^audio/webm$
                      abortcontent ^video/MP2T$
                      abortcontent ^audio/wmx$
                      abortcontent ^audio/mpeg$
                      abortcontent ^audio/aac$
                      abortcontent ^.application/x-mms-framed.$

                      2. In freshclam.conf don't forget to change to your nearest server. Do not touch one below described as "database.clamav.net is round-robin"

                      Mine is Australia

                      Uncomment the following line and replace XY with your country

                      code. See http://www.iana.org/cctld/cctld-whois.htm for the full list.

                      You can use db.XY.ipv6.clamav.net for IPv6 connections.

                            You can try this https://forum.pfsense.org/index.php?topic=120154.msg664657#msg664657 for a temporary work around but I believe that disable's the definition.

                            Otherwise you will have to contact sane security.

                                The alternative definitions have been triggering on iOS app updates of late.

                                Has anyone else seen this behaviour?

                                  The FPs need to be reported to the signatures maintainer. (But please understand that these things are mostly made for email AV filtering.)

                                            Hi

                                            Where does Clam AV store the files it believes are viruses (or does it even)?

                                            I'd like to be able to extract them to check against Virus Total / RE them etc

                                            Anyone know the answer to this?
