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

- Download HijackThis 1.99.1

- Unzip the hijackthis.exe file to a folder you create named C:\Program Files\HJT

- 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.

- Before running HijackThis: You must close each of the following:your web browser, e-mail client, instant messenger, and programs like notepad, wordpad, MS Word etc. And any other unnecessary running programs.

- Run HijackThis and save your log file.

- Post your log as an ATTACHMENT to your next message. (Do NOT copy/paste the log into your post).
