My project needs to perform virus scan on uploaded files via Azure AppService web app. Files will be stored in Azure Block Storage if they are cleaned. Otherwise, they are rejected to users.
My question: How should I implement this, does Azure provide built-in anti-virus scan?

Hi Sam,
We are running into the same problem, uploading a file on Azure File Explorer triggers Malware Scanning. However uploading the file from our app does not seem to trigger it.
What was the solution?
To update based on recent changes, Malware scanning for Blob storage with Azure Defender is now available

The Defender for storage is a possible solution, Azure Blob storage has an add-on to scan for malware, but this feature is currently in preview and cannot scan files exceeding 2GB.
