Hi again,
I downloaded a tool, What's running, from Tucows and this was a good one. When I examined the Avast module Aavm4h.dll, this tool clearly show that one instance of this module is used by three processes: ashServ.exe, ashMaiSv.exe and ashWebSv.exe. The other loaded instance is used by two processes: ashDisp.exe and iexplore.exe. So the module is loaded twice it seems, but shared by several processes.
Please correct me if I'm wrong.
