How to remove the About:Blank Hijackers in Windows XP/2000
(Also known as Hidden_DLL, Appinit_DLLs, About:NavigationFailure, \temp\sp.html, SE.DLL)
What this program does: When you open Internet Explorer your browser will be redirected to a page called About:Blank, sp.html, or About:NavigationFailure. If you attempt to change your home page to another site, it will not work and continue opening about:blank.
Tools Needed for this fix: Symptoms in a HijackThis Log may include, but not necessarily have all of the following:
R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Bar = about:NavigationFailure
R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Page = about:NavigationFailure
R0 - HKCU\Software\Microsoft\Internet Explorer\Main,Start Page = about:blank
R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Bar = file://C:\DOCUME~1\family\LOCALS~1\Temp\sp.html
R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Page = file://C:\DOCUME~1\family\LOCALS~1\Temp\sp.html
R1 - HKCU\Software\Microsoft\Internet Explorer\Main,HomeOldSP = about:blank
O4 - HKLM\..\Run: [sp] rundll32 C:\DOCUME~1\fujitsu\LOCALS~1\Temp\se.dll,DllInstall
If you have any of the types of symptoms then you most likely have this type of infection and should continue reading.

has finished you will see an image similar to the one below. Simply press
the OK button and then the Exit button to
