### Calamav cannot scan tar file and gzip files?

Hi,

I tried to scan tar files and tar.gz files using clamav(through squid, squidclamav and c-icap) but it just
pass through. Both these files contain the "eicar.com" test file.
But if it is a zip file then it works!!!

ScanArchive parameter is enabled in clamd.conf.

Do I need any special setting to scan these files? I am using a RHEL5 server and clamd/clamav version 0.98.5

### Unclear how to proceed after Windows install

I installed clamav-0.98.6-win32.msi on Windows. It added nothing to the
Start menu. After searching the registry I found clamav executables in
C:\Program Files\Sourcefire Inc\ClamAV, but they are all command-line
programs.

Your manual clamdoc.pdf is relevant only to Linux.

I have used Clam-Tk on Linux and it works well -- easy to install, easy
to use. I'm surprised at this baffling Windows version of the program.

Even with access to the clamd.conf man page on Linux (not provided in
Windows) I could not figure out how to fix the "Please define server
type (local and/or TCP)" error. The conf file options require specialist
knowledge that few Windows end users would have.

Do I have the wrong package? Or, is the Windows version of ClamAV just a
bare-bones toolkit for technical specialists?

### Clamav doesn't seem to work when we use HTTP POST with eicar.com.png file

Hi,

I have a clamd(0.98.5) + cicap(0.3.5)  + squidclamav(6.12)  + squid(3.1.14) on a RHEL5 box. We use this as a
virus scanning for scanning the files uploaded through a web form. It doesn't seem to work if I upload a png
file Actually the png file is just the "eicar.com" file but I renamed it to "eicar.com.png" because the
form only accept the .png files.

But it works beautifully when I upload  the

We did an strace on the clamd PID and found that,

1.  When I upload the eicar.com.png file it writes the tmp file with all HTML headers(including all the form
field values) and the multipart part. Then scans it. Returns the stream OK result.
2.  When I upload the zip file it correctly extract the zip file from the HTML POST request and create the tmp
file using the just the multipart data only. So it works

In the case #1 I find there are two req is going to clamd, it creates two tmp file, scans both and no virus found.
In the case of #2 it only create one file and found the virus.

Am not sure about is this something to do with the other components c-icap or squidclamav or squid.

See attached files for  the relevant part in strace for both cases.

### Mirrors 65.19.179.67

I believe this has come up a few times before, but it has never been resolved.

The mirror status page vanished when the new web site rolled out.  It wasn’t always accurate, but at least
there were some clues there.  Is there any chance of it’s returning some day?

My current issue is the 65.19.179.67 mirror which has failed 18 out of 18 times over the past several months:

> Mirror #5
> IP: 65.19.179.67
> Successes: 0
> Failures: 18
> Last access: Wed Feb 11 18:04:23 2015
> Ignore: Yes

Looks to belong to Hurricane Electric in Fremont, CA.

This mirror is clearly dead and needs to be taken out of service, yet it continues to be periodically rotated
in from this list:

> db.us.big.clamav.net.	60	IN	A	200.236.31.1

### Custom clamav rule to block exe and scr files in archive.

    Recently I have received some viruses that have scr inside zip
arhcive inside zip archive. And also there have been some cab's containing exe
files.

Since I have already blocked exe and scr files in exim mime check I did try
to search Google for blocking those files inside archives. And since I did not
have mutch success with it, I decided to post sample rules here.

I created exe_in_archive.cdb file in clamav database directory, that
contains:
Archived_EXE:*:*:.*\.exe:*:*:*:*:*:*
Archived_SCR:*:*:.*\.scr:*:*:*:*:*:*
Archived_PIF:*:*:.*\.pif:*:*:*:*:*:*
Archived_COM:*:*:.*\.com:*:*:*:*:*:*

### I have some queries about ClamAV

Dear ClamAV users,
Hi~ I am a student interested in security.
I have a few questions about ClamAV. I already understand that ClamAV can have the ability to quarantine an
infected file if it finds one.

So, I want to know,
1. I cannot find this ability (ability to quarantine) in user menual. could anyone let me know where it is ?
2. where is the infected files move to? and next ? user should be fixed(or removed) the infected files ?

I look forward to ClamAV user's response.
Best Regards.

~Chang~
