To stop / filter the spam adverts in email try Spam Bully, I got it and its ace, its automatically configures itself to work in Outlook expess and creates a spam folder, nearly all the spam goes into it, the program takes only a small amount of training, occasionally a non spam goes into spam folder, but you can cl;ick the NOT SPAM button to teach it that email address is not spam, any spam that go into your inbox you just press the spam button and thats where they go from then on, I think you can get a free 30 day trial from <A HREF="http://www.download.com">www.download.com</A> type spam bully into the search and it should find it for you.
