If you ran through my guide, then all the current infections should be gone. You did run each step in safe mode with networking, right?
If yes, then you're either getting a new infection each day, or your Symantec scanner is feeding you bad results.
Disable or uninstall the Symantec scanner, run through the guide again, and then install Microsoft Security Essentials, Avast, or Avira. Then, see if they notify you of any infections in the next few days.
