- Yes. What I do is log on to our novell server as user 'virus' with no
- privs at all and only write access to /tmp - I unpack there, then
- switch the machine off. (Reset isn't good enough). I *think* this
- is reasonably secure. I don't know if any damage could be done across
- our novell network while unpacking. You certainly *don't* want to unpack
- on a real hard disk. Net drives are relatively safe.
