Unzip HJT into it's own permanent folder before doing anything in order that the backups it creates cannot be deleted by accident. (Not a temporary folder or directly on the desktop (in a folder on the desktop is fine) & not directly on your hard drive). Rescan with hijackthis. When the scan is finished tick the boxes next to all these, then close all browser and explorer windows, and tell HijackThis to "Fix checked".
