I think you are using IE as your browser. Stop using IE from now on, and use FireFox. Install ZoneAlarm firewall. Browse the Net using FireFox only, since the Adware uses IE!! Whenever any program tries to connect to the Net, ZoneAlarm will prompt you to allow or deny it Net connection. If the program looks suspicious deny it Net access. You should also install good anti-spyware software like SpyBot or Spy Sweeper , download the latest updates and make a full System scan.
