Good luck. That reinstall took me all weekend, but besides eliminating the infernal "spyonyou" it also cleared up a few other software problems.
I found them with Norton AntiVirus 2002. Problem is that even though I quarantined them then deleted them, the SpyOnYou page still pops up from time to time and I've run the AntiVirus again and no Trojans. So it ain't trojans.
Ad-Subtract pop-up killer doesn't stop it either.
I'm sure that doing what you did would cure me too, but my concern is that however it got into my computor it can do it again - unless they quit trying.
