Let's dig deeper then:
  • Download Combofix to your desktop.

  • Doubleclick combofix.exe

  • Follow the prompts.
Don't click on the window while the fix is running, because that will cause your system to hang.

When finished, and after reboot if it asks for one, combofix will open again to gather the necessary information for the log. This may take a while so please be patient. When done, Combofix will close and a log should open called combofix.txt.

Post the contents of this log in your next reply along with a new hijackthislog.

Please do not post the ComboFix-quarantined-files.txt unless I ask you to.
