Download HijackThis Executable from here. Save it to your desktop.
Start HJT & press the "Do a system scan and save a log file" button. When the scan is finished a window will pop up giving you the option of where to save it. Save it to desktop where it is easy to access. Open the log file and copy the entire contents of the file & paste it into the body of your post. DO NOT FIX ANYTHING YET. Most of what is there is necessary for the running of your system.

==

Combofix should only be run when necessary. Let's see the hijackthis log before we go there.

here's the log:
