Hi Nozomi,

The following commands will tell you the user/group information for user=1000, group=1000 (as per the error message):

grep ":1000:" /etc/passwd
grep ":1000:" /etc/group

This will give you text name of the user/group that /var/lib/clamav should be set to.

You can change the user/group to the correct versions using 'chown' or 'chgrp' commands without using the names:

Both:
sudo chown 1000:1000 /var/lib/clamav

User Only:
sudo chown 1000 /var/lib/clamav

Group Only:
sudo chgrp  1000 /var/lib/clamav

Set the permissions to 0775:
sudo chmod 775 /var/lib/clamav

Get information on the directory owner/group and permissions:
ls -ld /var/lib/clamav

I hope this helps you get further.

Regards
        Mark.

Thank you for your reply.

I tried creating a vscan service account and changing the owner as you 
suggested,
The result of running freshclam did not change.

# ls -l /var/lib/
drwxr-xr-x 1 vscan vscan 4096 Aug 7 15:59 clamav

# freshclam

Sorry, this is not an answer.

How about this?

   # chown vscan /var/lib/clamav

The only problem is the permissions.

Regards.
