[windows xp]
Well, its locked tight. The screen is full of this message. I can't access anything else at all. ctrl-alt-del does't do anything. Safe mode hangs at mup.sys.
I tried hiren's boot disk and used spybot which removed some items but no change. mbam won't run from inside hiren's.

What else can I do. I can't find any way to access a restore point, but I'm trying to avoid the re-format and re-install route.

Ideas?

thanks
