  1. Please break your links…!!! (Change http to hxxp…!!)
  2. This needs further analysis by a malware removal specialist:
    Go to this topic http://forum.avast.com/index.php?topic=53253.0 for information on Logs to assist in cleaning malware.
    Use the information about getting and using the tools and attach the logs here, not in the LOGS topic.
