Install a system with what you need, then tar, bzip and FTP or netpipe the
whole of it across the network, onto another partition than the one you
are running now, edit and run lilo as required to boot the other partition
and then cross your fingers and do a 'shutdown -r -t1 now'. If you fail it
will hang so mistake(s) is not an option ;-). If tar or bzip are
contaminated then this will likely fail. There is no way to help a
compromised machine until you reboot it from media known to be virus free.
