Morning all

Friend of mine was duped by a caller allegedly from TalkTalk into giving access to her PC (she was actually waiting for a call from TalkTalk with a broadband issue) and it looks like some kind of SysKey password on startup that I can't seem to get rid of.

Anyone have any experience of getting shot of this on XP SP2?

I've pulled all her data and next step is re-install XP over the top, would prefer to rescue if possible, however I think the removal of it causes mega problems after?
