Possible Malware??

I just noticed on the StackCP control panel for web site hosting a warning about potentially Malware.

Not sure how long its had the warning but Latest scan was 9th November.

When I click on Full Report, it says its the file class-wpdb-admin.php and the exploit is wordpress.file.put.contents.0

The path for this file –

/public_html/wp-content/plugins/wp-database-backup/includes/admin/class-wpdb-admin.php
