FAQ Issue One: Start clamav failure, error needs to modify/usr/local/etc/clamd.conf and/usr/local/etc/freshclam.conf.

Workaround: The reason may be that when you run the./configure, There is no parameter --prefix=/usr/local/clamav To specify the installation path, which causes the default installation to the /usr/local/etc path.
