HI Vinvent, >Indeed, I believe this is caused by the fact that our applications are signed with a temporary certificate.
Yes, that make sense. It comes into my mind that we always use the same self-signed certificate here since a longer time. I'll try to generate a new one using the ADT, maybe that make a difference, not sure. Unfortunatley, it's hard to "debug" because the anti-virus-scanner out there behaves differently, not reproducable and sometimes it takes some days until an Air app is blocked. We're still using the latest Adobe AIR version, not sure if this could also be an issue. However, I expect to get rid of the last bit of Flex here until summer...
