Anything is possible and as much as I would like to assist you, uploading 595MB would take approx. 13 hours
using a 128Kbit/S(and that's on a good day!!), which is a bit to long for me!
Don't you have a kind of a debug version of Avast that I could try out for you? One that would generate a comprehensive error report file or so which I then could return to you?
That would be a lot easier(at least for me)
