Hi,

Is there anything about ClamAV v0.97.3 that would mean it's suddenly unable to fetch the daily updates via freshclam? I know it's an old version, but this is on a very old box running Centos 4 so upgrading isn't practical at the moment (for, you know, *reasons*).

Suddenly started seeing this whenever freshclam tries to run:

This started to happen yesterday after years of trouble free operation. Nothing on my box's configuration has changed between freshclam working and it not working.

Any pointers as to a possible cause would be most welcome.

Cheers
