I've had this problem for some time now, and I have run out of ideas about what to do about it. I've used a lot of anti-spyware scans, virusscans and I've been using crapcleaner for some time now, but it has made no difference. If I shut down my computer (or restart) it shuts all programs, and then keeps running for between 15 and 20 minutes:zzz: before it finally turns of the computer. It's just annoying , and it makes me wonder what windows thinks it's doing in that time. Help would be very much appreciated.
