Isw27, which WinXP? Home, Pro, Media Center, etc.? Have you installed Service Pack 3? You need to note that the link provided by cogs10 is a four year old thread and there have been many changes since then, including Service Pack 3 being released.
According to your post, you are running MSE and Avast, two anti-virus programs which will cause conflicts. You should remove one or the other. Or disable Avast to see if that is causing the conflict.
