ClamAV not doing regular scans

Hi all.

I’m using Seafile 12 Pro and followed the docs regarding installing clamAV here:
https://manual.seafile.com/12.0/extension/virus_scan_with_clamav/

After that if I do

cd seafile-server-latest
./pro/pro.py virus_scan

It works properlly.
But if latter I add some EICAR files to my shares, it never detects them.

Did this already happened to someone else?
I really would thank for some help on what to try to modify.

Thank you.
