[clamav-users] clamav: problems with updating definitions database

[Micah Snyder (micasnyd)]

Hi all,

In ClamAV 0.102, the ReceiveTimeout should be set to `0` to disable it so the  download completes on a slower connection.  We made this change in the default  on 0.102.2, but for 0.102.1, you will need to set it to `0` manually if you encounter this issue.  Also some distros seem to provide a freshclam.conf where the ReceiveTimeout is set.  0.102.2 users may also have to change the conf in this case.

Matus, it's okay to run `sudo freshclam`.  Freshclam will switch to the DatabaseOwner ("clamav") account to do the update.

Regards,
Micah

    why? linux users rarely need antivirus.

    Why? automatic update should work as good as manual. Unless

    this is a mistake. freshclam process has to run under user "clamav" - you
    may have apparently created files which later instances of freshclam won't
    be able to remove/update.
    
    go to /var/lib/clamav, chown all files to clamav:clamav and let freshclam daemon
    do its work.

    slow internet connection probably?
    the default on debian is
    
    ReceiveTimeout 30
    
    it's in seconds; you can increase it if really needed.
