Hi. First of all you need to update hijackthis to version 1.98.2. Run hijackthis & go to *Config\Misc Tools\Check for update on-line*. If the site is down, go here. Remove the old version by deleting the file manually. Unzip the new version into the hijackthis folder.
Click My Computer, then C:\
In the menu bar, File->New->Folder.
That will create a folder named New Folder, which you can rename to "HJT" or "HijackThis". Now you have C:\HJT\ folder. Put your HijackThis.exe there, and double click to run it.
Close all (browser) windows & rescan with hijackthis. When the scan is finished place a check in the box to the left of the following entries & click 'fix checked':
