[clamav-users] LibClamAV Error: cli_ac_addsig: Signature for Win.Worm.Fadok-6328944-0 is too short

[Cervinka, Andreas]

I got the following Problem since yesterday:

----
LibClamAV Error: cli_ac_addsig: Signature for Win.Worm.Fadok-6328944-0 is too short
LibClamAV Error: cli_parse_add(): Problem adding signature (3).
LibClamAV Error: Problem parsing database at line 2793
LibClamAV Error: Can't load daily.ldb: Malformed database
LibClamAV Error: cli_tgzload: Can't load daily.ldb
LibClamAV Error: Can't load /var/lib/clamav/daily.cvd: Malformed database
----

I restored older files in the /var/lib/clamav directory and the scans completed successfully.
Has anyone got an idea how to solve this issue?
