On CentOS you should be able to check with: `yum info zlib-devel` Alternatively, take a peek in /usr/include/zlib.h for the line starting with: #define ZLIB_VERSION

I was not able to determine which version of zlib is installed, what is a command with options that will allow me to provide that data point to you? Thanks for help so far. Jay Hi Jay, Is your system 32bit? As noted in our 0.100.0 release notes, we found that Centos 6 (and 5) provide an old version of zlib (1.2.3.3) that will fail to properly extract the ClamAV databases. You can update to 1.2.4 to resolve the issue, but I recommend at least 1.2.9 or newer as 1.2.8 has at least 4 published CVE's. Regards, Micah Micah Snyder ClamAV Development Talos Cisco Systems, Inc.

I still am getting the malformed database issue even when directly downloading the files using wget from the clamav.net<http://clamav.net/><http://clamav.net<http://clamav.net/>> site. I also verified that the clamav package was good, here is that command and the result: [root@centos jhart]# rpm -V clamav-0.100.0-1.el6.i686 S.5....T. c /etc/freshclam.conf Can you see any issues above, or point me to something else to try. I was figuring that maybe rpm would tell me I got a bad package and I'd reapply it, but I don't think that is the case. Do you want my freshclam,conf parameters? thanks for the help. I've tried just about everything I know to do and have been able to research.
