Small Business version, AutoSandBox, and Microsoft ClickOnce (tm) installations

Avast Business Avast Endpoint Protection

Using Microsoft’s ClickOnce technology, we publish our application to an in-house LAN server for unattended installations; the users can simply type something like the following into their browser address bar:

//inHouseServer/apps/app1/publish.htm

and the application files are downloaded and installed onto their computers, and any prerequisites are fetched; in our particular case, the prerequisites are Microsoft .NET Framework runtime downloaded automatically from microsoft.com.

The program crashes in the Sandbox. We would therefore like to know

  1. Is it possible to designate //inHouseServer as a trusted file origin/source, so the application will pass muster and avoid AutoSandboxing because “The file origin/source is suspicious” and/or “the file is executed from a remote/removable media”?

  2. Is it possible to tell Avast to look at the certificate issued which Visual Studio “signs” the app with, so that it avoids AutoSandboxing because “the file prevalence/reputation is low”? Can we artificially “pump up” the reputation of the files?

Thanks
