2013-03-02 22:58:52.561968500 Update failed. Your network may be down or none of the mirrors listed in /etc/freshclam.conf is working. Check http://www.clamav.net/support/mirror-problem for possible reasons.
This is a workaround to have a new database without complaints of clamav. use a root terminal to perform these commands.
Shutdown clam so clamd.socket file is removed
service clamd stop
Navigate to clamav folder
cd /var/clamav
Remove ALL files from folder to provide clean slate for update process
rm -f /var/clamav/* (you could skip the -f & confirm every file delete for safety)
Current Clamav version is clamav-0.97.6
rpm -q clamav
clamav-0.97.6-1.el5.rf
Update clamav to latest version if required '''it will Not downloading clamav-db'''
yum update clamav
Restart clam
service clamd start
Update sigs
freshclam -v (--no-dns can be used if just -v fails tho I haven't struck this issue)
Check output from freshclam to make sure update completes sucessfully.
Current working dir is /var/clamav
Max retries == 6

For completeness & to be absolutely sure signal-event post-update; signal-event reboot, then go through the logs post reboot to make sure everything started correctly. This is not necessary for this procedure but doesn't hurt.
