# Update a Malware Scanner global configuration

PATCH https://api.modulards.com/api/public/v1/preset-malware-scans/{preset_malware_scan}
Content-Type: application/json

Updates one Malware Scanner global configuration. Send only the fields you want to change.

- `schedule` is replaced whole: when you send it, it carries every field its frequency needs (`frequency`, `start_hour`, `timezone` and the day its frequency asks for); when you leave it out, the stored one stays.
- A new schedule reaches every website that uses the configuration and reschedules their next scan.
- `default: true` makes it the configuration new websites receive and takes the mark off the previous one; `default: false` clears it.
- The stored premium state is what gates the add-on, as in "Create a Malware Scanner global configuration" and "Assign websites to a Malware Scanner global configuration".

**Body**

All fields are optional and take the same values as in "Create a Malware Scanner global configuration".
- `name` (string, optional): the configuration's name.
- `schedule` (object, optional): `frequency`, `start_hour`, `timezone` and the day its frequency asks for.
- `extensions` (array of strings, optional): file extensions skipped by every scan.
- `max_file_size` (integer, optional): bytes.
- `default` (boolean, optional): whether new websites receive it.

**Errors**
- **403**: the stored configuration is premium and the organization has not subscribed the add-on.
- **422**: `schedule.frequency` other than `monthly` on a basic configuration; `tier` is sent (a configuration's tier cannot change after creation: create a new one instead); `region` or `batch` is sent.
