The solution for the future (after cleaning your system) is quite simple and will solve most of the current problems:
Go to
http://www.opera.com/download/index....atform=windows
Download Opera with Java and install it. Then go File - Quick Preferences - Refuse popup windows. Problem solved!
Most people I know who use windows use Opera for browsing and Eudora for mail

Basically don't use IE or Outlook and you will have very few problems
