I came across the following web page and thought it maybe of some interest to people here. Some of you may already be aware of it. So apologies in advance if you have. Anyway here it is.
They have got a cool script running on the page that does a quick check for browser parasites. A good description of what Adaware/spyware etc is. And a list of common crud on the left of the page that will link to more info. Including removal instructions.
