When changing to XP I'd do yourself a favour and stop using AOL as your ISP.
If you're on broadband you can have much better deals with other companies - check out
www.adslguide.org.uk to see what one is best.
Also - carry on using firefox like I recommended to stop any toolbars from getting in your way, and also to stop popups.
Cheers,
Andy
P.S. Need a hand with any of it then catch me on MSN mate
