About:blank problem

So, now my IE has started to change the home site to about:blank, so I ran the simplified removal of about:blank.
I did all that was told in the guide, but I still have the same problem, and I hope that you can help.

 

*cough* help, please?

 

In HJT Choose Open the Misc Tools Section choose Process Manager, Highlight:

Choose Kill Process

Now scan and have HJT Fix the following:

Download
- Pocket Killbox
- ExplorerXP

Now run Pocket Killbox:

Choose Tools -> Delete Temp Files and click the RED X.

Run Killbox.exe. Paste the below filenames into KILL BOX one at a time. Check mark the box that says "Delete on Reboot" and checkmark the box "Unregister DLL" (If available) Click the RED X and it will ask you to confirm the file for deletion…say YES and when the next box opens prompting you to reboot now...click NO...and proceed with the next file. Once you get to the last one click YES and it will reboot. Note many of the file list below may not exist but we need to check for them anyway.

If Killbox does not reboot or you get a Pending Operations type error message just reboot your PC yourself.

Now boot into SAFE MODE

Open ExplorerXP navigate to and DELETE the following: (Some of these may have already been deleted by Pocket Killbox)

Now run CCleaner. If you have Windows XP delete the contents of C:\WINDOWS\Prefetch.

Then, as an added precaution, Go to Start -> Run and type: cleanmgr and then click OK. Make sure the boxes for these are checked:
Temporary Files
Temporary Internet Files
Recycle Bin

And Click OK.

REBOOT to Normal Mode.

Post a fresh HijackThis along with the BitDefender and Panda logs from earlier.
