i have a friend whose computer is rubber ducked, probably due to him never
having a firewall or virus protection.

i intend to back it up and then reformat the hard drive followed by a
re-installation of windows xp. 2 questions:

1. will this remove any viruses?

2. if i back up the files using windows xp back up in xp pro before the
reformat , can i then re-install/reinstate the files using windows xp home
edition for the new installation. in other words will the back up file from
the pro version open up when restored to a version of windows xp home
edition?
