When i log onto the internet through the BT Broadband Browser, the browser keeps changing pages for no reason, it does this for about 10 secs before it settles down, can anyone help me please?

I am running on XP, have run Spybot and have an up to date Norton Anti virus system, which i have just run, though it found no errors. Also when i try to shut the PC down in the normal way an Error message appears.

The log is as follows
