If you fix the afd issue that occurs after installation and also the cant flush registry hive issue, then I will love it, but, update after update, its the same, and it is avast that causes these 2 issues, they go away when avast isn't installed, that's if your lucky enough that the uninstallation doesn't break and corrupt the networking after avast is removed, sometimes afd stays broke/corrupted after avast is removed, this as happened on windows 7 64bit, and now its happening on windows 8 64bit, ancillary function driver breaks, also avast does something to the registry as it cant be flushed.I bet if you people with avast premier or security look in the event logs you will see those 2 errors that never get resolved. They occur on a clean install of w7 and w8 so its not 3rd party conflicts. The AFD error really need resolving as sometimes the whole network is completely bust after removal of avast, all the network drivers have yellow triangles next to them, only way to resolve is a clean install, its not a minor error, its major. Sorry for my rant, its just that these 2 errors have been around for as long as I can remember, they never get resolved.
