Describe the bug

One of our customers uses GData Internet Security. .

For our Blazor Wasm application, GData thinks that files written to the browser's cache storage are Trojans. We have implemented DLL bundling as per the docs.

This does not seem to be the case for other Blazor Wasm applications. For instance, Asteroids.Blazor, a .Net 6 Wasm application, produces no such warnings. I have tried other recent Blazor Wasm sites out there, and can't find another one that produces these warnings.

You can try our application at https://demo.test-inmydata.com/demo

If you wish, I can supply one of the cache files that GData doesn't like. I'm not going to attach it here, considering that it's a file that antivirus considers a Trojan.

We are in communication with GData regarding this being a false positive. However, there's an indication here that Multipart Bundling may not be enough to solve the Blazor Antivirus problem.

Expected Behavior

Application should run with no Antivirus warnings

Steps To Reproduce

  1. Install GData Internet Security
  2. In Chrome or Edge, navigate to https://demo.test-inmydata.com/demo

Exceptions (if any)

No response

.NET Version

6.0.102
