      The Foxhole definitions are the ones responsible for scanning inside of Zip files I believe.  If it's still being blocked then what is it saying is blocking it?  If it still says Foxhole then there should be some way of clearing those definitions out of ClamAV.  Maybe a Freshclam?  I'm not sure.

      Looking at the virustotal link it appears it is not a virus so maybe it is a false positive?

        Stewart you can see in my above post, in the first 'code' section it reports that sane security.foxhole.xxx is the responsible database(s). I'm not exactly sure which that is though.

        I removed the 3 foxhole databases and it still blocked. I have just removed the sanesecurity database and I will see if it still blocks.

        In the end I might try and reporting the blocks to SaneSecurity as false positives and see what they say. Although on their site they say and database with 'unofficial' on it is not theirs.

          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

            Hi All,

            Just popped in to say if you find any more FP's on files with foxhole_filename.cdb

            I'll need a direct file download url, so I can download and scan this end.

            I've fixed a couple of the FP's already, so thanks for pointing them out.

            Cheers,

            Steve

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

                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.

                      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.

                            Great thread. Thanks so much for this information and to sanesecurity for db's

                            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.

                              DatabaseMirror db.au.clamav.net

                                    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.)
