DavidR, your hint is appreciated, but look: Most of us who experience that problem see two facts: There are already at least 4 threads running on that problem, two of them just died away. The more recent ones started anew, and there seems to be no help until now. We are users and are troubled by that warning, which is clearly tied to the program AshServ.exe. The shutdown process is hardly manipulable by a user. So what can we do to analise the problem, how could we delay the process of shutdown?
As far as I could gather, most warnings appear after some user-manipulation has been performed, as calling ABOUT, or updating manually, or just opening the Avast screen. Without doing anything such, I have the impression that the shutdown runs normally, but this is not a clear fact, just a feeling. The warning occurs also, if the PC was idle before shutdown for some lengths, like 5 minutes.
I guess as a user we need some help, how to go about analyzing that warning.
At least this nuisance seems not to influence the proper operation of Avast or the whole PC. but something has to be done about this...
