Download Spybot

Make sure to follow the instructions for updates prior to running the scan.
Click on "Search For updates" After the search has completed, the available Updates will be listed. Click "Download updates." The Updates will self install. The screen will change and the program will come back and be ready to use.
Sometimes the default Download Location will produce an Error. If that happens, look in the right panel. There you will find a small arrow next to the name of the current Download site. Click on it for a list of alternate sites. One of those should be able to retrieve the files you have selected.
Scan later while in safe mode...
Run HJT again and put a check:

You did get rid of the cookies right? If not do so now.
Reboot to safe mode and see if you can complete a scan with spybot and/or adaware.
