I am no expert on HiJackThis, but I can see a few things that would worry me.
You did not list your brand, model, and age of computer... info that would be helpful.
You have Spybot Teatimer, Avast, AVG, Stealth Malware Detector, and Symantec Security on that computer. Those grouped together on one machine will slow things down dramatically. I suggest you uninstall all of them, defragment, then run CCleaner or other registry editor, then reinstall the ones you really find helpful... either Avast, AVG, or Symantec, but not all three.
