I understand that you need help in order to get rid of the malware that is present on your system - But you need to help us first..
I notice that you never scanned with an Antivirus previously before starting this thread - because you don't even have an Antivirus installed
This is somewhat suicidal in today's digital world.
That's why I want you to install one first!!
* Please install Avira Antivirus: http://www.free-av.com/
This is a free Antivirus.
Perform a full scan with Avira and let it delete everything it is finding.
After reboot, open your Avira and select "reports".
There doubleclick the report from the Full scan you have done. Click the "Report File" button and copy and paste this report in your next reply together with a new HijackThislog.
Then we'll start from there, because it really makes no sense otherwise that we clean this up manually if an Antivirusscan is not present which should be able to deal with most and prevent further reinfection.
