After installing again the last ClamAV and update the OS to latest updates for 
RHEL 6.7 x32, now the AV is downloading the ddbb but fail on CVD header and 
delete the ddbb
I got the next errors:

I've made some investigation and the people on google says that this is a BUG 
with zlib, and the last zlib for RHEL 6.7 x32 fail to correctly decompress the 
CVD signature database.

A solution is to use a newer version of zlib but I'm not able to find a newer 
version of zlib for this version of RHEL 6.7 x32. Newer than the one for the 
RHEL repositories.


Any advice?


Regards.

Sounds like some strict security policy requirement.

It's possible to install working av on system.

Just in case you're thinking that installing ClamAV on a system which
you do not keep up to date is some kind of alternative to keeping the
system up to date, it is nothing of the kind.  Not even close.
