  # plesk db "select * from ServiceNodeConfiguration where name='virusfilter'"
  +---------------+------------+-------------+-------+
  | serviceNodeId | section | name | value |
  +---------------+------------+-------------+-------+
  | 1 | mailServer | virusfilter | drweb |
  +---------------+------------+-------------+-------+
