Virus scanning on uploaded files?

Hello, I have a client with an unusual request. We have an upload field on their contact form, and they want to know if any virus scanning is performed on those files (or that email) between the user submitting the form, and it being sent to the email account associated with the contact form. They need to know for their cybersecurity assessment. I have written Webflow about it, but their support barely, if ever responds (and hasn’t about this - been weeks). Any help here?

If they do it’s not documented as far as I can tell. I also have never seen anyone report a notification. So I would proceed under the assumption that this is not the case. Regardless, no one receiving file attachments should consider them safe to open without scanning them with an up to date virus / malware scanner, and preferably more than one.
