Having difficulty deleting spyware

I've downloaded Adaware, Spybot, etc trying to get rid of spyware but it keeps coming back so I'm turning to the MG forums for help. Here's my log. Thank you in advance for your help.

 

You have the about:blank hijacker and a few other problems. There are no signs of you doing the READ ME. You must do this before we continue.

Now, please follow ALL the steps in this Sticky thread READ ME FIRST BEFORE ASKING FOR SUPPORT: Basic Spyware, Trojan And Virus Removal


After doing ALL of the above if you still have a problem:

Make sure you have HijackThis 1.99.1 and follow the guidelines on where to install it and how to post a log as an ATTACHMENT.
All instructions are covered in the sticky thread NO HIJACK THIS LOG FILES BEFORE READING THIS: HJT Tutorial & LOG File Posting


Now post a Hijack This log as an ATTACHMENT to your message (Do NOT copy/paste the log into your post). Please close unnecessary running programs before you run HijackThis. You must close each of the following: your web browser, e-mail client, instant messenger, and programs like notepad, wordpad, MS Word etc.

DO NOT run Hijack This from the Desktop, a temp folder, or a sub-folder of C:\Documents and Settings, or choose to run it directly from the downloaded ZIP file. Place it in its own folder, for example C:\Program Files\HJT
