I cant get the firwall to start on avast premier 2014, looks like the driver installed ok, just wont start, in services I can manually start it but still doesn't register in avast, ive just updated to windows 8.1, which lead to the deletion of my avast premier. I have a feeling that the 8.1 update hasn't deleted something properly from thre previous install, if id of known avast wasn't going to be there after the update I would of uninstalled first, didn't have any messages telling me whats being deleted or anything, all I did was press the download button in the store, and 8.1 installed itself. Made a total mess of nearly all my desktop apps,many of them needed repairing and overwriting.
