Hmm just a thought here, (yup Iknow you and the tech have tried all) but can you acces your daughters PC from yours over the network?
If so, then get a copy of
Spybot and see if you can remove the offending Spyware with thios program
from your PC it might be worth a try rather than going thru the whole rigmarole of installing and connecting networks <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
