Thanks for your reply.
Time is at something of a premium at the moment but I have run Root Kit Revealer as quoted in the MS page you posted.
I have attempted to copy and paste the results here and also save them to My Docs but without success. A screen grab pasted into a Word document is the best that I have achieved so far.
Anyway, the point is that it has chucked up fifteen discrepancies but I have to confess that I find interpreting the results something of a 'challenge'.
I am not exactly cheered by Micosoft's throwaway line: " If you are unsure as to how to remove a rootkit you should reformat the system's hard disk and reinstall Windows".
When I have a little more time (elderly mother in hospital) I'll resort to transcribing the results and posting them here.
Perhaps you'll be able to assist me further?
Thanks again,
