How can I make sure transferred files don't contain malware or viruses?

I've been approached by someone overseas who wants to transfer files to me using a standarf file upload service. How to I make sure they don't contain viruses or malware? Is there an Upwork file transfer service that helps with that?

Hi David,

You can use the attach file option on Upwork messaging.
