Hi
Open notepad and copy/paste the text in the quotebox below into it:
Save this as "CFScript"Code:File:: C:\WINNT\system32\vtr.dll C:\Program Files\hlpsrv.exe C:\WINNT\amph.exe Registry:: [-HKEY_LOCAL_MACHINE\software\microsoft\windows nt\currentversion\winlogon\notify\stp68_2007] [HKEY_LOCAL_MACHINE\software\microsoft\windows nt\currentversion\windows] "appinit_dlls"=-
Then drag the CFScript into ComboFix.exe as you see in the screenshot below.
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.
