If you used the HJT parsing here it is worthless. It is years old, has never been updated AND definitely is NOT for use with Vista or Windows 7. In fact the use of ANY HJT parser is never recommended. This program is meant to be used to scan the computer and then to copy/paste the log onto a forum like this one. Unless you know what each and every single entry on the log means you should not be reading it yourself.

Plus, you ran the old version of HiJackThis which is not configured for use on Windows 7 so your scan gave false and incorrect results. The newest version 2.0.4 is the one that should be use and that can be found here

Run the new version and then please Copy/Paste, DO NOT ATTACH, the log back here and I will take a look.
