I will try that.
One other thing about the simple user interface, it seems to have some sort of picture at the bottom of it that only shows as a red cross on my computer. Before you just ticked the box to not show it again, I have never changed the avast4.ini file before, other wise what is the point of the check box?
Now I know most people say make sure you have cleaned your cache plus Internet files along with offline files. I always do that, so it isn't that. I also made sure I have the latest Macromedia Flash player 8, just in case it was that.
I still think it is something to do with 4.7 of Avast, because I have never had a problem with it before.
