I think your problem lies here:
R0 - HKCU\Software\Microsoft\Internet Explorer\Main,Start Page = res://C
WINDOWS\system32\shdocpl.dll/security.htm#subID=MPV;401
I think it is a homepage re direct. But I am quite new to this, (due to neccesity, not choice)
I would do a google search on shdocpl.dll, to check, and see if there are hints for its removal. if it is a baddie.
