Not to clutter this thread up with too much more seriousness

, if anyone is having problems with sites or a lot of broken images as I was describing and think your HOST file may have been altered without your knowlege, there is a freeware called HOSTman that as the name suggests lets you manage your HOST file.

This is what I used to unblock all the entries that were in mine as a result of downloading one of the altered Kazaa programs.
You cannot edit your HOST file directly because it is in use when Windows is running, you must either know how to do it in DOS or use software like HOSTman that will easily do it for you.
This is not something that Adaware or any other spyware/trojan detector will alert you to.
