Virus Scan seafile pro 6.05

Hi togheter,
I would like to set up virus scan. now i installed clamscan on centos.
I added this line as described here…to opt/seafile/conf/seafile.conf

https://manual.seafile.com/deploy_pro/virus_scan.html

[virus_scan]
scan_command = clamscan
virus_code = 1
nonvirus_code = 0
scan_interval = 2

Now if i run ./pro/pro.py virus_scan in opt/seafile/seafile-server-latest it seems to work.
But how can i run it automatic? I downloaded EICAR.zip to test but it seems not to check automatic after e.g. 2min.
Many thanks in advance
Stefan

Please excuse. Works flawlessly.
