Very sorry, but I deleted Avast. If I had the files I would send them, but I don't want to mess up my system with more crashes, so I will not install again. This problem however is pretty fundamental, so I think it is Avast's responibility to get it fixed by themselves.
If they pay me, I'll do some testing. LOL
MAybe there is a Function to disable Avast AV for certain Programs, like Outpost... Then they won't get into eachothers way.
