You should make her a slipstreamed copy of XP including all the XP updates 
to this point that she can use if she needs to reinstall again.

Not many I imagine.  Vendors don't ship machines to customers with the 
unpatched 2001 verson of XP.  Even small shops selling white boxes have 
enough sense to apply patches for their customers.  Anyone capable of 
building their own computer certainly wouldn't be stopped by such problems.

I think the only possible continuing victims would be those who use their 
restore discs from 2001 to fix some problem.  They would be likely 
candidates for infection.  I guess if they didn't get updated restore 
discs, they'd be taking their machines into local computer shops or calling 
their vendors for help.
