There are following files, with some constants. In order to avoid occupying too much system resources, it is recommended to use the default parameters.

• Scan Path config src/config.rs
• Engine config src/model/engine/clamav/config.rs
• Database config src/model/engine/clamav/updater.rs

• SCAN_DIR_CONFIG define the scan directory list and recursion depth
• SCAN_DIR_FILTER define the filter directory list matched by prefix

• CLAMAV_MAX_FILESIZE define the maximum file size of scanned files (skip large files)

Get default database url with default password clamav_default_passwd:

wget http://lf26-elkeid.bytetos.com/obj/elkeid-download/18249e0cbe7c6aca231f047cb31d753fa4604434fcb79f484ea477f6009303c3/archive_db_default_20220817.zip

The clamav scanner plugin will load local database from TMP_PATH/archive_db_default.zip with password ARCHIVE_DB_PWD, besides, it will also check ARCHIVE_DB_VERSION from ARCHIVE_DB_VERSION_FILE and ARCHIVE_DB_PWD.

More details in src/model/engine/updater.rs

The default database includes cropped clamav database and open source yara rules.

root@hostname$ ls
main.ldb  main.ndb  online_XXXXXXXX.yar

More details in Clamav Docs

• Notice
  • There are currently a few limitations on using YARA rules within ClamAV

scanner plugin task (Seen Elkeid Console Doc):

• Dir scan
• Fulldisk scan
• Quick scan

• Creation time / birth_time is not available for some filesystems

error: "creation time is not available for the filesystem

• Centos7 default compile tool-chains didn't work, high version of tool-chains needed.
