I'll be glad to help you with the problem, but ask that you first go through the steps in our Virus and Malware removal thread HERE.
When you have finished, please attach the logs from Malwarebytes and Superantispyware.
Do a new scan with HijackThis afterwards and paste the new log in your next reply.
Please be sure your antivirus program is up to date. The current version of AVG is v9.
