Please help with my log

I'm having about:blank prob. I have tried several antispywares, like spybot, ms antispy, spybouncer..None of them seems to work. Now I'm using spyware doctor. There are also a lot other probs other than this about:blank. Different software has different scan result. I am following the steps and here attached is my Hijackthis log. Please help! Thanks so much.

 

Please print out these instructions so that you can operate with All Browser Windows CLOSED.

Please make sure System Restore is OFF and the Viewing of Hidden Files & Folders is Enabled as per the tutorial.



Now, look in Task Manager (Ctrl-Alt-Del) for the following running processes and, if you see any of them, try to END them:

atllt.exe

ntwc.exe

Now scan with HijackThis and Check the Boxes for the following:

Make sure All Browser Windows are Closed when you Click FIX.

Again, make sure All Browser Windows are Closed when you Click FIX.

NOW:
Please boot into Safe Mode with the Viewing of Hidden Files & Folders Enabled and navigate to and DELETE the following if they should remain:

C:\Kingsoft ←–– Delete this whole folder if it exist!

C:\WINDOWS\atllt.exe

C:\WINDOWS\ntwc.exe

C:\WINDOWS\system32\d3df.dll

C:\WINDOWS\msagent\chars\apun.exe

C:\WINDOWS\System32\dfrgsnap.exe

NEXT:
Run CCleaner and Spybot S&D and have Spybot fix what it finds.
Note: Dont forget to update Spybot S&D by selecting "Search For Updates"

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 Windows , Scan with HijackThis and attach the new log.
Let me know of any problems you may have encountered with the above instructions and also let me know how things are running now.

Good Luck!
