I am trying to clean a toshiba laptop with Windows XP Media Edition that is infected with at least smitfraud, maybe zlob, plus ? These infections took place with NOD32 v3 installed. NOD32 installed and computer scanned Mar 3rd 2008. Infection first appeared 5:45 am March 24th. All NOD32 settings were at default. I have scanned with NOD32 set to maximum cleaning strength - last scan shows nothing found. Internet Explorer 7 starts with about:blank, even though set to google. I have noticed a folder date-stamped at time of infection labeled "Helper" which appears to be empty, but can't be deleted. Starting IE7 now just shows a blank page for about:blank, where before it tried to load a vermin type site selling antivirus program. (I have screen shots). Has shown "security alert" in system tray. Have tried to clean with Spybot S&D, Smitfraudfix, vundofix, and tried using restore - both to a few days before infection, and to date of NOD32 install. ALL result in stop F7 error. Any ideas besides restoring to factory? I do have DVD, but there are many other installed programs & configurations. Any point in removing the drive and scanning it in another computer?
