Don't forget that some of this crap loads and keeps TSR
programs in memory. If you delete the crap, and the
program sees it is missing, as soon as you connect to the
internet again it will reload it. My suggestion in this
case is to run the program while you are offline to clean
the machine. Then reboot to make sure the offending
program is gone. Then run the check again while you are
still offline. If you come up clean you are probably ok.
