Have him load up his machine and just delete Autoexec.bat. Point out to him that any normal user couldn't do such a thing to a Linux machine because they don't have the permissions to. Not exactly breaking in, but a lot of security problems do originate from friends using the computer or family, or anyone else who can turn it on, not just the net...

A friend has just put satellite internet access in, and is running a firewall called "ZoneAlarm" (or Zonealert, can't remember). He's got a fixed IP, and has challenged me to prove that Windows is less secure than Linux by breaking into his machine and leaving a non-destructive message in his AUTOEXEC.BAT file...:-) Then I can talk to him about converting to Linux...:-) Anyone have any clues about this program ?
