My mailserver has delays in sending/receiving e-mails. Checked the logs and encountered the following:

Service clamd start gave me the following error:

Re: Clamd: Segmentationfault/Malformed database -> e-mail delays

ClamAV cannot start. Please try below steps:

*) Remove all files under /var/lib/clamav/.
*) Execute "freshclam" again.
*) Start ClamAV after freshclam finished.

Any other ideas? Thank you.

Re: Clamd: Segmentationfault/Malformed database -> e-mail delays

Which mirror site do you use in /etc/clamd.conf?

Re: Clamd: Segmentationfault/Malformed database -> e-mail delays

You mean in /etc/freshclam.conf?

I found the following lines:

DatabaseMirror db.nl.clamav.net
DatabaseMirror db.local.clamav.net

Update1: Also tried some other mirrors. (DatabaseMirror db.us.clamav.net)
Same errors.

Update2: I decided to download the files manually, ran freshclam and got the following results:

ClamAV update process started at Mon Oct 28 20:45:11 2013

bytecode.cvd is up to date (version: 228, sigs: 43, f-level: 63, builder: neo)

Tried to start clamd

service clamd start

                                                           [FAILED]

Edit 3: Friend of mine gave his working clamav/libs. Still getting errors.

service clamd start
Starting Clam AntiVirus Daemon: LibClamAV Error: cli_loadhash: Invalid value for the size field
LibClamAV Error: cli_loadhash: Problem parsing database at line 77

LibClamAV Error: cli_tgzload: Can't load daily.hdb
LibClamAV Error: Can't load /var/lib/clamav/daily.cvd: Malformed database
ERROR: Malformed database

Any ideas what I should try to get this to work?

Re: Clamd: Segmentationfault/Malformed database -> e-mail delays

No idea at all. I suggest you post this issue in ClamAV mailing list instead.
