LibClamAV Error: cli_loaddbdir(): No supported database files found in /var/lib/clamav – CentOS

When I tried to Scan the /home directory I got this error.

[root@ip-172-31-34-67 ~]# clamscan /home
LibClamAV Error: cli_loaddbdir(): No supported database files found in /var/lib/clamav
ERROR: Can't open file or directory

It shows on supported database files found in /var/lib/clamav, which may caused the issue?

    You will need to use the command:

    freshclam

    to create the neccesary virus database files.

    This can then be set up as a service to periodically update the database.

    Run :

    • sudo service clamav-freshclam stop
    • sudo freshclam
    • sudo service clamav-freshclam start

    This clam business is tricky, because sudo freshclam will get you locked for 24 hrs if, like me, you’re innocently trying to build from source and don’t have everything quite right. Being limited to work on the problem once every 24 hrs makes for a difficult build/install indeed. Only by chance on a 3rd-party website did I find that an alternate way to get the database is to download from https://database.clamav.net/daily.cvd, then manually copy it into /var/lib/clamav
