Explorer Appcrash

I rebooted my machine on 5/5/2007 and now it boots and explorer crashes with
the following details. I have run several adware, spyware and virus removal
tools but the problem still persists. Anybody have suggestion on how to fix.
The computer is a Toshiba A105 Satelite Laptop with the free express upgrade
to Vista Home Premium. I was trying to perform the startup recovery but the
DVD is not bootable and could not find the tool on the dvd.

Thanks for any help.

Where is the file xuoce.dll on your system?
What are the properties on that file? Who made it?

The only reference I saw to this was that that file might be part of
SmitFraud--

I don't know much about this whole Smitty issue, but that's a touch more
information than it sounds like you had before. Do your tools detect
SmitFraud... ?
