Windows alerts me that Avast Premium Security / Sensitive Data Shield is downloading files from cloud storage. Why does Avast download my files and what does it with them after they are downloaded?
When does the alert appear, is it connected to a specific action you do? Can you please post a screenshot of the alert?
I don’t think Avast downloads files from storage intentionally but it’s possible that a component is touching/scanning them which triggers the download. I’m surprised that Windows could recognize it’s the Sensitive Data Shield though…
