There are many such topics relating to this, generally slow opening and browsing, etc. of IE. Disabling/removing the Avast Online Protection Add-on, seems to resolve it.
That said there are some that are reporting a recent VPS update has resolved that.
I can’t directly confirm that as I don’t use the Avast Online Protection Add-on for IE as I rarely use it and it is IE8 on this XP Pro SP3 system.
