kathy asks a question to do with PCs, Super_Geek dives in and tries to

Being 'illegally networked' is different to being hacked. If you know
the person who has hacked you, do as sgopus says and report them. Here
are some links that may help you do just that:
http://securityadmin.info/faq.htm#trace describes how to use
www.network-tools.com and
http://visualroute.visualware.com, and then
info on reporting hackers.
The information stored on the drives is probably the key element in the
hacker's ability to by-pass your firewall. Try getting a new firewall,
but first you must rid the files on those drives.
If you have wiped the drives already, and the files are coming back, you
must either be infected with a virus which is putting the files back,
the format tool has been altered, (unlikely but possible,) or they are
being copied from your network. I recommend removing all network shares
(or at least putting them as read-only,) and then formatting the drives.
If the primary hard disk (the one with the OS,) is separate from drives
D, S, F and G, use the fdisk command in dos to delete the whole
partition rather than formatting. Then use the dos format tool as
opposed to the windows one.
Now that you have been hacked, re-installing windows would be sensible
to remove all traces of the hack. However, if this is awkward, you need
a good trawl through the registry and some serious scanning using
spy-ware and up-to-date virus scanners.

FIREWALLS
ZoneAlarm is the most widely used, but there's also www.agnitum.com,
www.kerio.com and www.sygate.com.
