    Ok, first I want you to update your Java Runtime

    Update your Java Runtime Environment
    • Click the following link
      Java Runtime Environment 6 Update 4
    • After the download locate and double click the installer jre-6u4-windows-i586-p-iftw.exe
    • Go to add/remove programs and you should have 2 Java versions listed, uninstall the old version in your case Java 6 Update 2

    Then proceed through the instructions in the link I provided in my first response (15 steps -> you are definitely infected)
