Thank you for not replying to my query.
Problem appears to be solved.
I reviewed the "Windows XP Fix" Removal Guide (here: http://www.bleepingcomputer.com/virus-removal/remove-windows-xp-fix
). I believe the "Windows XP Repair" was a variant of this one, such originality these hackers show. I apparently needed an RKILL.exe file with a different name. Downloaded and ran the RKILL and the TDSSKiller again and it worked this time!
Malwarebytes and super anti-spyware where both able to run completely, identify and remove a few additional threats.
Now the computer is no longer redirecting and no invisible internet explorers are running so all appears to be kosher once more.
MS Security Essentials is installed and running as well as SUPER Anti-Spyware and WinPatrol so I think the computer should be good now.
Only question is this: In the realm of the free anti-virus is MS Security Essentials good enough or is Avast a better choice?
