Have you been able to run MBA-M? Your computer is grossly infected and either you are going to have to be able to run one of these tools or honestly reformat is the next step.
You don't have an anti-virus program installed on there, yet you played a multitude of games...good way to get infected. You have at least one back door trojan on there and probably many others. Your host file entries are back in your log meaning this thing is bringing in more and more.
You might try this:
Download Combofix save it to the DESKTOP. DON'T run it yet.
We are almost ready to start ComboFix, but before we do so, we need to take some preventative measures so that there are no conflicts with other programs when running ComboFix. At this point you should do the following:

* Close all open Windows including this one.
* Close or disable all running Antivirus, Antispyware, and Firewall programs as they may interfere with the proper running of ComboFix.

Once these two steps have been completed, double-click on the ComboFix icon found on your desktop. Please note, that once you start ComboFix you should not click anywhere on the ComboFix window as it can cause the program to stall. In fact, when ComboFix is running, do not touch your computer at all and just take a break as it may take a while for it to complete.
Windows may issue a prompt because ComboFix does not have a digital signature. This is perfectly normal and safe and you can click on the Run button to continue.
ComboFix is now preparing to run and when it has finished you will see the Disclaimer screen you should press the number 1 key and then press the enter key to continue.
ComboFix will create a System Restore point so that if any problems occur while using the program you can restore back to your previous configuration. When ComboFix has finished creating the restore point, it will then backup your Windows Registry.
Once the Windows Registry has finished being backed up, ComboFix will disconnect your computer from the Internet. Therefore, do not be surprised or concerned if you receive any warnings stating that you are no longer on the Internet as your connection will be completely restored at a later stage in the program.

ComboFix will now start scanning your computer for known infections. This procedure can take some time, so please be patient.
While the program is scanning your computer, it will change your clock format, so do not be concerned when you see this happen. When ComboFix is finished it will restore your clock settings to what they were previously. You will also see the text in the ComboFix window being updated as it goes through the various stages of its scan.

When ComboFix has finished running, you will see a screen stating that it is preparing the log report
This can take a while, so please be patient. If you see your Windows desktop disappear, do not worry. This is normal and ComboFix will restore your desktop before it is finished. Eventually you will see a new screen that states the program is almost finished and telling you the programs log file, or report, will be located at C:\ComboFix.txt.
When ComboFix has finished, it will automatically close the program and change your clock back to its original format. It will then display the log file automatically
You should now post this log here when all is complete.
