When the current signature database is faulty (for example, false positive occurs or system performance is degraded), you can roll back the current signature database to the previous version through version rollbacks.
You can roll back to only one version. If you perform version rollbacks repeatedly, the version rollback is implemented between the current version and the rollback version.
update rollback { av-sdb | cnc | file-reputation | ip-reputation | ips-sdb | sa-sdb | location-sdb | asset-sdb }
