I use clamav 0.100.1 portable version from the website https://www.clamav.net/downloads .

When I use the old config from clamav 0.99.4, run clamd.exe then clamdscan.exe to scan a file return total error: 1. It work fine for old version of clamav.

Could you please help me if I have missing/wrong config anything?

Attach the config clamd.conf and freshclam.conf
