Any ideas about how to check Azure's blob storage for viruses?
Our application stores files uploaded from our customers to blob storage. These files are exchanged between different parties (our customers and their suppliers). Is there a way to check the uploaded files for viruses? The Antimalware service seems to just check virtual machines, but I cannot get any information about using it to check files as a service.
A great solution would be if we could store such a file in Azure Storage as an "on hold" file till it is checked. Then we would need a service to check this file and returns the result. If the file is virus-free we could then move it to the final destination.

Azure Storage is just... storage. There are no utilities built in, such as antivirus. You'd need to do your antivirus check on your own. Since antivirus tools typically only work with local OS storage, you'd need to place your "on hold" content (as you referred to it) on a local disk somewhere that you have antivirus installed and then copy to blob storage once your antivirus check is done.
How you accomplish managing this, and which software you use, is up to you. But VMs, App Services, and Cloud Services (web/worker roles) all have local disks available.
