There are online virus-scanning tools you can use via API such as:
https://scanii.com/ and
https://www.virustotal.com/en/documentation/public-api/ . Alternately you
can use a Compute Engine
machine<https://cloud.google.com/products/compute-engine/>
/Managed VM <https://developers.google.com/cloud/managed-vms>, install an
anti-virus scanning engine, then run all your uploaded files through there.

If you don't want to handle virus scanning yourself, you could try
requiring users to upload files from a trusted source. For example, Google
Drive virus scans files under
25MB<https://support.google.com/a/answer/172541?hl=en>- you could have
users upload to GDrive, then select files using the Drive
API <https://developers.google.com/drive/v2/reference/>.
