Ok I've done all that - removed quite a bit of stuff by the look of it.
Seems a bit better - most sites are ok, but on a couple the scrolling is awfully slow - and the mouse wheel doesn't work at all, yet others it's absolutely fine.
I'm on a 2mb connection.
Sometimes things take an age to happen (such as opening folders) but the next minute it's fine.
I found a folder called ie-spyad - is that anything to be worried about?
