We are producing a software (C# / .NET 2.0), which is provided for download on a website.
Now this is a special program for only a few clients. As a consequence, many antivirus programs (Norton, Mc Afee, Avira, ... ) do not know our program and bring up a false alarm ("suspicious ... " - "not known by the community ... "etc.).
Many clients feel insecure, or do not know how to handle this.
So, how can this be handled in general? Can we add some sort of "certificate" that our program is guaranteed to be virus-free ?
