Hi 
Don't uninstall Norton if you're using it. I just asked because it didn't seem to be running correctly on the last HijackThis log.
We'll continue
Open notepad and copy/paste the text in the quotebox below into it:
Code:
Driver::
aaudstum
Registry::
[-HKEY_LOCAL_MACHINE\~\Browser Helper Objects\{A53F96EB-0452-09AD-2E26-0CC2BD21149C}]
[HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
"Saue"=-
"Baaobvek"=-
"Spol"=-
[HKEY_CURRENT_USER\software\microsoft\windows\currentversion\policies\system]
"Ghp`amfUbrhLds"=-
[HKEY_CURRENT_USER\software\microsoft\windows\currentversion\policies\explorer]
"NoInstrumentation"=-
"Mn@iboddPubswLfov"=-
"Mn@mlrf"=-
"MnOndNeg"=-
"MnQtm"=-
[hkey_local_machine\software\microsoft\windows\currentversion\explorer\shellexecutehooks]
"{FBF23B40-E3F0-101B-8488-00AA003E56F8}"=-
[-HKEY_LOCAL_MACHINE\software\microsoft\windows nt\currentversion\winlogon\notify\urqpnol]
Save this as "CFScript"

This will start ComboFix again. After reboot, (in case it asks to reboot), post the contents of Combofix.txt in your next reply together with a new HijackThis log.
