I got to Avast 4 and there was nothing after that...............so it didn't "show" me anything!
What does nothing mean, no folders, no files or you just couldn't access the folder, what ? We need detailed information to be able to help, we also need answers to questions asked, we still haven't got a clue what providers are running, not 7 providers, 5 running.

Don’t worry about the registry for now as I said “If that doesn’t resolve it check this:” before contemplating that. That is why I previously suggested the reinstall and running the uninstall utility which should remove all registry entries, but since you have done that already as Bob mentioned.

However, this latest problem further convinces me that this install is screwed, sorry about the technical term. That is why I feel even though you have done it once, you follow the instruction above in FULL print the page so you can do it in order whilst off line.
