Hi Ged,

Thanks for your help. I deleted bytecode.cvd and main.cvd but the service still not be started. The output is as below. I can wait till you are available. Thanks.

[root@tplinuxuhgdb2 clamav]# ls
bytecode.cld daily.cld main.cld mirrors.dat
[root@tplinuxuhgdb2 clamav]# systemctl start clamd@scan.service
Job for clamd@scan.service failed because the control process exited with error code. See "systemctl status clamd@scan.service" and "journalctl -xe" for details.

I haven't looked in depth at the output but at first sight this looks
wrong. Again I don't know if it's causing your problem. For both the
main.* and the bytecode.* signatures in your database, you have both a
.cld and a .cvd file. They are two different representations of the
same thing; a .cvd file is compressed and a .cld file is not. Perhaps
you can try deleting one of them, then (re)start clamd.

The build information is a little overwhelming compared to mine (see
below). I don't know what it might be telling me without spending a
bit of time on it, and I don't have enough spare time at the moment to
do that. If you can wait, I'll take a look at it when I get a chance.
It would be much less effort if you built ClamAV from source yourself,
and test the resulting clamd binary on your system - or even if I did
that for you.

Ged.
