  • A minimum of 1 config is required.
  • Specifying a config on the command line (-c | --config) will override the loading of the default configs

Check if signature are being loaded

**Run the following command to display which signatures are being loaded by clamav

clamscan --debug 2>&1 /dev/null | grep "loaded"
