i see rstones12 has beat me to admitting once again i don't know everything...
as it turns out when you run Hijack this (esp. when you perform any fixes) backup files are made in the same directory. if the user selects the wrong line or fixes on thier own this could cause more damage to the system than good... and the files may need to be restored, from the backup files... it would be very bad to loose those.
and this is the same reason HijackThis can not be run from a CDrom

it can't make the backups...
a readonly folder will also cause problems when trying to run Hijack this in that folder...
