Thanks, Avast’s engine appears to be passing it okay, but it might be heuristics in the software.
Anyway, those error codes are both related to connectivity, and shouldn’t be related to Flash loading. Specifically, the 8004882a means something unexpected was received during authentication, and the 80072ee7 is a “can’t connect” error (although usually a problem with DNS). Was this working before, or are you a new user?
