Since that error message can be triggered by any driver or various other things, I don't think there's a lot anyone here can do for your system.
If you go down the steps listed by MS when the error occurs AFTER an XP install...you'll see that it's a circle. Check drivers, restore, recover, repair install...
The fact is...anyone one of the programs installed to assist your examination/cleanup of malware...may have drivers which may be creating the STOP error. All of those programs have drivers.
And the fact is...we cannot even be sure that it's a driver which created that error...the malware on your system may have impaired files which now result in the error.
I'd try the Microsoft guidance, as far as is possible. That failing, I would do a clean install.
Maybe someone else has a better idea/plan/approach.
