Ok, 2nd try, I hope it helps:
[img=http://img460.imageshack.us/img460/258/winverscreenshotgz5.th.jpg]The message screen shot is difficult to take because windows shows this message in the task list after a restart but only for a few seconds.
My Vista Business thinks Avast seems to need additional rights at startup and completely prevents it from starting up.
The result of this is: Avast does not start up when I start up or restart my PC which is a Notebook.
When I restart WindowsVista Business, there is no red ball, no blue ball in fact there is no ball at all. And there are no Avast components whatsoever visible in the task list.
After I manually start the blocked at startup module "Avast! service GUI component", the Avast virus protection asks for confirmation to start and after I confirm it's ok to start I get the blue ball and all is fine until the next restart of Windows Vista Business takes place.
Very strange
