The only undesirable thing I see is Norton. I strongly recommend that you get rid of Norton, as it hogs resources and seems to cause other problems as well. Good replacements for Norton are the free AVG and Avast antivirus programs (only have one installed at a time, however). If you have any trouble removing Norton, see this thread.
Then go and read this and post a fresh HijackThis log as an attachment into this thread. Be sure to follow the instructions for moving and renaming HJT.
