Vista Boot Loop After Vundo?

Hi, I will try to keep this as brief as possible and want to say any help will be PHENOMENALLY appreciated!

For the last three days I have, successfully to a degree, been removing what appeared to be a variance of the Vundo/Virtumundo trojan from my computer.

Programs used include;
VundoFix
Virtumundobegone
Symantecs vundo removal tool (I forget the name, sorry)
AVG
SpybotSearchAndDestroy
Combofix
SuperAntiSpyware
DrWeb CureIt
I have used more programs no doubt but those are the ones i can remember (again sorry)

Now whenever I try a normal startup I get the ACER screen (F2,F8 access screen), the usual Vista loading screens and the welcome screen all as usual. However the welcome screen stays on for 10 secs, which is usually only on for a brief 2 secs, and then the whole system restarts with no sign of my desktop. This process continues over and over.

I can however get on to my desktop and user account "as normal" with no sign of the previous virus by using F8 and "Last known good configuration".

I have tried System Repair (from F8 at startup), no success. I have no System Restore points, a symptom of the virus I guess, as I guess this would solve whatever the problem is.

The problem is, with the fashion of now not giving out Op System discs with new computers, I have no way of reinstalling Vista and so a complete wipe of the system is not a feasible option, though I am beginning to think it is the ONLY option (other than keep using F8/Last known good configuration that is).

I wonder if the problem is that the virus has altered my Boot process or something, sorry to be so vague but I am at best an amateur techy and at my wit's end!

Again any help or suggestions will be gratefully received and attempted

Thankyou, David
